Dosimeters and their Differences: Active, Passive, and Digital Dosimeters

There are many different types of radiation dosimeters available for use today, and they all play a critical role in an organization’s adherence to comprehensive radiation safety protocols. These dosimeters assist in the collection of exposure data in the workplace, aid in assessing potential health risks, and allow organizations to maintain regulatory compliance. 

In this article, we’ll dive deeper into the differences in dosimeters currently available for use in the workplace.

We hope you find this article informative, and as always, we look forward to hearing your feedback! 

Radiation Dose 

It is normal for those that come in contact with radioactive materials and X-ray generating devices during the regular course of their employment (or those who have the potential to be exposed to radiation), to carry personal radiation dosimeters. 

Personal Dose Equivalent 

Personal dose equivalent is an operational quantity for individual monitoring of radiation exposure. 

The personal dose equivalent (sometimes referred occupational dose or dose) is defined as the dose in tissue at an appropriate depth in human body. 

Personal dose equivalent, Hp(0.07) also known as shallow dose equivalent is the quantity that is used for the assessment of the dose to the skin and to the hands below elbow and feet below the knee. 

Personal dose equivalent, Hp(10) also known as deep dose equivalent is the quantity that is used for the assessment of the dose to the whole-body including areas above the elbow, knees and including the head.  

Personal radiation dosimeters are specifically designed to record and indicate dose equivalent to ensure the dose is within the allowable limits and regulatory compliance is achieved. 

Personal Radiation Monitoring 

There are many different types of dosimeters on the market these days that typically fall into one of the following categories: active, passive and digital. Below we’ll explore the different dosimeter offerings currently available. 

For more information on personal radiation monitoring in a multitude of workplace settings (including medical, veterinary, dental, and more), please refer to our recent article, “Radiation Badges to Use Based on Your Specific Work Needs.” 

Different types of dosimeters like active with electronic personal dosimeters, passive like osl and tld, and the digital dosimeter like NetDose

Active and Electronic Dosimeter 

Active and electronic personal dosimeters measure instantaneous doses, which can provide a visual and audible alert to possible exposure, the dose and dose rate, and follow the variations of radiation exposure over time. Personal radiation detectors – like electronic personal dosimeters (EPD), personal emergency radiation detectors, and a quartz fiber dosimeter – play a major role in active dosimetry. Active dosimeters generally require an external source of energy, like a battery to operate. 

These dosimeters have continuous monitoring can allow for audible alarm warnings at preset levels of exposure, as well as a perpetual live readout of the radiation dose accumulated. This dosimeter is to supplement passive and semi-passive dosimetry in the case of high radiation levels and/or dose optimization purposes but typically isn’t accredited for reporting purposes.

Passive Dosimeter 

Passive dosimeters (TLD and OSL) do not need an external source of energy to operate as the signal is stored in the device. They are also known as integrating dosimeters, which means they only give an estimate of the cumulative dose. Passive dosimeters record how much radiation an individual is exposed to over a specific period of time (i.e. a week, month, quarter, or year). They do not provide direct readout of dose and analysis is completed in a lab. 

Digital Dosimeters 

A digital dosimeter is a modern dosimeter used for measuring the dose a person receives. This dosimeter can provide real-time information about the measured dose for the individual wearing the device. As a semi-passive badge, it has a battery that can read dose levels at any time and is stored within the device. 

Digital dosimeters are usually worn on the outside of clothing (the same as passive dosimeters)- generally on the chest or torso – to represent the radiation dose to the whole body. By wearing a digital dosimeter in that spot, it’s able to monitor exposure of most of the vital organs, while also representing the bulk of a body’s mass. 

Introducing RDC’s New Dosimeter Solution: The NetDose Whole Body Digital Dosimeter 

The NetDose  dosimeter (Type 600295-A) utilizes silicon photomultiplier (SiPM) technology for real-time dose determination with a minimal reportable dose of 1 mrem (0.01 mSv). 

The NetDose dosimeter is used to monitor occupational exposure to an individual working with radioactive materials emitting gamma rays and/or X-rays and X-ray generating devices. 

This dosimeter ensures the dose received remains within the allowable dose limits and provides organizations with real-time insights and peace of mind in confirming safety in the work environment. 

RDC's NetDose Digital Dosimeter

Energies Measured: Photons (both gamma and x-ray radiation). Photon: 17 keV – 6.7 MeV. 

Reporting Periods: On-demand with routine read weekly – no need for the usual routine of shipping of badges. This dosimeter takes incremental dose readings every hour and stores results in memory, which is transmitted up on demand or automatically weekly. This gives organizations more autonomy and control over radiation dose report times. 

The NetDose Whole Body Dosimeter can be easily reassigned to other workers and the dosimeter can keep track of who had the exposure at what time.

What is a Digital Dosimeter and is it Right for You? 

Technological advancements have made the range of dosimeter solutions available to organizations considerably more robust. With so many options on the market, understanding the needs of your organization has never been more important. 

In this article we’ll explore what a digital dosimeter is, how they could be used, and who benefits from their use. We hope that you find this article informative, and as always, we look forward to hearing your feedback! 

Minimizing Ionizing Radiation Exposure 

Ionizing radiation is a form of energy that acts by removing electrons from atoms and molecules of materials, such as living tissue, water, and air. There are five types of ionizing radiation: alpha radiation, beta radiation, neutron radiation, and electromagnetic radiation (i.e. x-rays and gamma radiation). 

Since ionizing radiation has the ability to alter molecules within the cells of our body, too much exposure over time can cause serious health problems (like certain types of cancer). 

If your organization has employees that work with or have the potential to be exposed to radiation, the monitoring of these levels of exposure is crucial. Monitoring radiation exposure minimizes the potential health risks that accompany radiation exposure and ensures that your organization is compliant with regulations. 

Calculating Radiation Dose and Personal Dose Equivalent 

Generally, those in contact with radioactive materials or x-ray generating devices during the regular course of their employment (or those who have the potential to be exposed to radiation), wear personal radiation detectors or radiation dosimeters. These dosimeters are specifically designed to record and indicate the dose received by the whole body and extremities. 

A radiation dosimeter measures occupational dose, which is the dose received by an individual in the course of their employment when their assigned duties involve potential exposure to radiation. 

Personal dose equivalent is a measure of the biological damage to living tissue as a result of exposure to radiation. Also known as the ”biological dose,” dose equivalent is calculated as the product of the absorbed dose in tissue multiplied by a quality factor, and then sometimes multiplied by other necessary modifying factors at the specific location. 

What are Digital Dosimeters Used for? 

A digital dosimeter is a semi-passive dosimeter used for determining the dose equivalent for the individuals that are wearing it.  These dosimeters provide real-time information about the measured dose for the individual wearing the device. 

What are digital dosimeters used for?

What are the Advantages of Using Them? 

The advantages of digital dosimeters over traditional passive types are that continuous monitoring can allow for faster insights into radiation exposure, as well as a perpetual live readout of the radiation dose accumulated. The ability of instant dose insights makes digital dosimeters both easy to use, and very effective. 

Digital dosimeters are a very effective way to monitor your employees that receive a wide range of doses. For example, it’s very effective monitoring individuals that receive very low doses as well as individuals that are prone to receiving higher doses during the course of their employment over a wide range of occupations and industries. In the case of the workers that are receiving very low doses, a digital dosimeter will help you save time and money by reducing the logistics associated with shipping the dosimeters back and forth to the processor. For those employees receiving higher doses, more frequent monitoring will help you run a better ALARA program and be proactive in controlling the dose as opposed to being reactive. 

Digital dosimeters are generally used in situations where elevated levels of radiation are potentially present, or personnel are operating in a dangerous radiation zone. 

Like any other whole-body dosimeter, digital dosimeters are to be worn on the outside of clothing – generally on the chest or torso – to represent the radiation dose to the whole body.  

RDC’s New Dosimeter Solution: The NetDose Whole Body Dosimeter 

RDC’s new NetDose dosimeter (Type 600295-A) utilizes silicon photomultiplier (SiPM) technology for real-time dose determination with a minimal reportable dose of 1 mrem (0.01 mSv). 

The NetDose dosimeter is used to monitor occupational exposure to an individual working with radioactive materials emitting gamma rays and/or X-rays. This dosimeter ensures the dose received remains within the allowable dose limits and provides organizations with real-time insights and peace of mind in confirming safety in the work environment.  

RDC's NetDose Digital Dosimeter

This dosimeter takes incremental dose readings every hour and stores results in memory, which is transmitted up on demand or automatically weekly. This gives organizations more autonomy and control over radiation dose report times. This also allows the Radiation Safety Officer (RSO) and end user to make adjustments to work habits and reduce occupational exposure based on this feedback.  

The NetDose Whole Body Dosimeter can be easily reassigned to other workers, and the dosimeter can keep track of who had the exposure at what time.

Why Should an Organization Make the Switch to Digital Dosimeters? 

Cost Savings: 

The elimination of shipping requirements allows an organization to save money. Organizations that have experienced a history of lost badges can avoid these fees moving forward, as well as the gaps in dose reporting that such circumstances cause. 

Peace of Mind: 

On-demand dose reports provide an organization with the peace of mind that their occupational radiation workers are protected and the doses received are ALARA and within the regulatory limits. This also provides relief to workers knowing they’re either in a low-risk environment or can help proactively investigate any radiation exposure concerns. 

Autonomy: 

The ease of assigning and reassigning badges online, and the ability to upload dose reports when it is convenient – rather than being tied to a schedule – lead to increased autonomy within an organization’s radiation safety program. Should your organization experience employee turnover, the easy reassignment of badges can be a big benefit of using digital dosimeters along with the on-demand reporting. 

The above three factors combine to highlight the overall convenience of using digital dosimeters.

9 Reasons RDC’s New Digital Radiation Dosimeter Is Right for Your Organization 

We’re excited to introduce our newest dosimetry solution, the NetDose Digital Dosimeter! In this article we’ll explore why using this digital dosimeter could make the most sense based on the needs of your organization. 

We hope that you find this article informative, and as always, we look forward to hearing your feedback! 

How Does a Digital Dosimeter Display Ionizing Radiation Exposure? 

There are five types of ionizing radiation: alpha radiation, beta radiation, neutron radiation, gamma radiation, and x-rays). You’ll remember that ionizing radiation is a form of energy that acts by removing electrons from atoms and molecules of materials (i.e. living tissue, water, and air). 

If your organization has employees that work with or have the potential to be exposed to radiation or radioactive material, monitoring the levels of exposure they receive is vital. Generally, those in contact with radioactive substances during the regular course of their employment (or those who have the potential to be exposed to radiation), carry personal radiation dosimeters. These are also sometimes referred to as personal radiation detectors. 

A digital dosimeter is a semi-passive radiation dosimeter that is used to estimate ionizing radiation dose of the individual wearing it. Personal dose equivalent is a measure of the biological damage to living tissue as a result of exposure to radiation. Digital dosimeters provide a real-time direct display of information about the measured dose for the individual wearing the device. 

RDC's Digital Dosimeter provides real-time direct display of dose report readout.

Radiation Dose Reporting with Digital Dosimeters 

Organizations that have switched to digital dosimeters have placed a significant amount of value on the convenience of being able to upload dose results whenever it’s convenient for them, instead of being tied to a set schedule dictated by an external team. This increased autonomy makes dose reporting with a digital dosimeter more convenient than alternative dosimetry solutions. 

The Specs: RDC’s NetDose Digital Dosimeter 

RDC’s new NetDose dosimeter (Type 600295-A) utilizes silicon photomultiplier (SiPM) technology for real-time dose determination with a minimal reportable dose of 1 mrem (0.01 mSv). 

The NetDose dosimeter is used to monitor occupational exposure to an individual working with radioactive materials emitting gamma rays and/or X-rays.

Your Organization Should Make the Switch to RDC’s NetDose If: 

1) Cost Savings are a Focus 

The elimination of shipping requirements allows an organization to save a considerable amount of money annually. Shipping costs are most pronounced for clinics with a small number of badges who return them for processing monthly or quarterly. 

2) Convenience is Priority 

The ability to upload dose results when it is convenient – rather than being tied to a schedule – leads to increased autonomy within an organization’s radiation safety program.  

3) History of Lost Badge Shipments 

Organizations that have experienced a history of lost badge shipments can avoid these fees moving forward. This also reduces the gaps in dose reporting that such circumstances cause. 

4) Frequent Employee Turnover 

The ease of assigning and reassigning badges online makes personnel changes less stressful and more cost-effective.

5) Work Requirements/Needs Call for On-Demand Dose Readings 

On-demand readings and dose reporting are crucial for organizations whose employees have the potential to experience elevated levels of radiation or work in a dangerous radiation zone. 

6) Energies Measured Include Photons 

NetDose measures photons (both gamma and x-ray radiation) and takes incremental dose readings every hour to provide on-demand reporting. 

7) Quality = Peace of Mind 

NetDose provides an organization with the peace of mind that their occupational radiation workers are protected. 

8) Service Standards within the Company | When Accreditation is Required 

NetDose is an NVLAP accredited (NVLAP Code 60295-0, Thermo Fisher Scientific Dosimetry Services) semi-passive radiation dosimeter with a Lower Limit of Detection (LLD) of 1 mrem (0.01 mSv). This means this dosimeter reports doses down to very low levels.  

Quality Service Standards with RDC

The NetDose dosimeter can be configured to record doses at various intervals, providing a comprehensive overview of cumulative radiation exposure. Additionally, the device monitoring the dose rate per hour (incremental exposure) throughout the week offers a more detailed analysis. This allows users to identify outliers in exposure rates and make informed adjustments to radiation protection techniques. By analyzing data for spikes in dose rates and modifying factors like time, distance, or shielding safety can be enhanced. Specific tasks or activities can be done with more granular data than a month, week, or day.

How To Choose the Best Personal Radiation Detector for Each Employee

If you have employees that work with – or are exposed to – radiation, it’s essential to monitor their radiation exposure levels to minimize health risks. One effective way to do this is by using a personal radiation detector (PRD).

Equipping each of your employees who has the potential to be exposed to radiation with a radiation dosimeter will help monitor their exposure and minimize health risks. There are several types of PRDs on the market with many of them being representative of the field you are using them in and meeting the regulatory requirement. Choosing the right personal radiation detector requires careful consideration of several important factors.

In this article we’ll explore what some factors to consider (such as sensitivity, accuracy, and compliance requirements) when choosing the best dosimeter to meet your employees needs.

We hope that you find this article informative, and as always, we look forward to hearing your feedback!

The Best Way to Minimize Potential Radiation Exposure

Radiation protection is crucial to those working in environments where ionizing radiation is present (these workers are known as occupational radiation workers). Minimizing radiation exposure is vital to the safety of these workers. For this reason, the US Nuclear Regulatory Commission (NRC) established a body dose limit for occupational exposure for people working with radioactive material or ionizing radiation (for example x-ray imaging equipment) over a defined monitoring period.

There are five types of ionizing radiation: alpha radiation, beta radiation, neutrons radiation, gamma radiation, electromagnetic radiation (think x-rays). The dose limit functions as an extremely important form of protection for radiation monitoring in the workplace.

If you’re unclear on certain safety issues, in many cases your organization will have a radiation safety program, and you can work with your radiation safety office to ensure you are doing everything you can to minimize employee exposure to radiation. 

How To Capture Radiation Dose

Generally, those in contact with radioactive substances during the regular course of their employment (or those who have the potential to be exposed to radiation), carry personal radiation detectors or dosimeters. These dosimeters are specifically designed to record and indicate a measure of the accumulated dose absorbed. Dosimeters measure occupational dose, which is the dose received by an individual in the course of their employment where their assigned duties involve potential exposure to radiation.

Personal Dose Equivalent

Personal dose equivalent is a measure of the biological damage to living tissue as a result of exposure to radiation. Also known as the ”biological dose,” dose equivalent is calculated as the product of the absorbed dose in tissue multiplied by a quality factor, and then sometimes multiplied by other necessary modifying factors at the specific location. 

Factors To Consider When Choosing a Personal Radiation Detector

Sensitivity

Sensitivity is of the utmost importance when it comes to choosing the right personal radiation detector for a given situation. There are different types of radiation badges available depending on the radiation energies your workplace is exposed to. Each type of badge has its own sensitivity range and detection capabilities, which we will discuss further below.

Accuracy

Accuracy is another crucial factor when it comes to deciding which dosimeter is best for an occupational radiation worker. The detectors ability to accurately measure and record exposure to radiation is paramount to safeguard the health of your personnel.

Dosimeter fade and lower limit of detection (LLD) should be considered when researching the appropriate radiation badge for your practice. 

Fade is the phenomenon of losing signal after the irradiation took place. This is important because a participant could receive a great amount of dose in the beginning of the wear period and by the time the wear period ends a great deal of signal is lost and occupational dose get underreported.

Dosimeter lower limit of detection plays an important role in deciding if it is suitable for your needs. When you are considering the LLD of different dosimeters you need to consider if the amount listed by the process is relevant for the wear period that you are trying to use, because lower limit of detection is a function of wear date. For example, an LLD of 1 mrem might be suitable for 1 day wear period or freshly annealed dosimeters but not for a quarterly frequency.

TLDs offer a significant improvement over older film badges in terms of accuracy. They maintain their accuracy across a wide range of environmental conditions and can provide precise readings even at lower levels of radiation exposure.

OSL dosimeters offer another high level of accuracy. They are extremely precise across a broad spectrum of radiation types and levels, which makes them ideal for monitoring even minimal exposure to a radiation source.

Compliance Requirements

Radiation monitoring requirements are dependent upon federal and state regulations. It’s important to research what is required of your organization in order to maintain a compliant radiation dosimetry program. 

A range of considerations should be the type of radiation energy exposure in your workplace, the wear period frequency for dose reporting, the type of radiation badge and calculation needed for accuracy and using an NVLAP accredited dosimetry service provider to stay in compliance.

To find out your compliance needs you can refer to your radiation safety officer (RSO), your equipment licensing, and your state regulators.

Radiation badge for pregnant worker

Placement of Radiation Dosimeters

In addition to deciding what type of personal radiation detector is best, there are also multiple options for their placement. How employees should wear a personal radiation detector depends on the nature of their work responsibilities, and how they come into contact with radiation.

Ring

A ring dosimeter is worn on the finger and is ideal for employees who handle radioactive materials directly, as it can closely monitor the amount of radiation exposure to the hands.

The TLD-XBG Extremity ring badge is available for radiation workers whose job functions potentially require their arms, legs, hands, feet, fingers, and toes to receive a higher exposure.

Benefit: Ring badges can be used by veterinarians taking x-rays – i.e. having to hold the animal down during the exam. These dosimeters accurately assess the personal dose equivalent at the site where it’s worn.

Wrist

Wrist dosimeters – worn similarly to a watch – are useful for those working in environments where they may be exposed to gamma radiation. The wrist badge is a good choice for workers whose arms may receive a higher exposure.

The Standard Type 82 TLD-XBG badge or Type 83 TLD-XBGN badge for neutron is fitted with a Velcro strap to be worn around the wrist. The wrist badge is available for radiation workers whose arms may receive a higher exposure, used due to dexterity issues, or even safety reasons.

Benefit: Wrist badges are an alternative to ring badges, specifically in nuclear medicine where the dose distribution is different on various parts of the hand.

Wrist badge

Whole Body

Whole body badges are worn on the torso and provide a general assessment of radiation exposure to the entire body. This is especially suitable for workers in nuclear facilities or industries where full body exposure is possible. 

TLD Whole Body

The Standard Type 82 TLD-XBG badge or Type 83 TLD-XBGN badge for neutrons are used to monitor occupational exposure to a single individual working with radioactive materials. “Whole body” is considered to be the head, torso, arms (above the elbow), or legs (above the knee).

Benefit: TLD whole body dosimeters have been a trusted technology for decades and are still highly efficient and widely used today. 

OSL Whole Body

Similar to whole body TLD badges, OSL badges are generally worn on the collar, waist, or torso, with the label facing the source of the radiation. The standard OSL badge (or Type 84 badge for photon monitoring) is a 2-element beryllium oxide (BeO) badge with a minimum reportable dose of 10 mrem (0.10 mSv), and a LLD of 1 mrem. These badges are used to monitor occupational exposure to a single individual working with radioactive materials to ensure the dose received remains within the allowable dose limits.

Benefit: A major benefit of OSL dosimeters is that they provide for the possibility of repeated readout. This means that OSL dosimeters are often archived for multiple years, and then can be re-read, as the dose does not fade. OSL dosimeters can also be read with only light (unlike a TLD dosimeter which must be heated), which helps simplify the design. Their low dose rate sensitivity is also a benefit. Finally, OSL dosimeters are not impacted by heat or water. 

OSL badge

Fetal Monitoring Badges

These are specialized dosimeters designed for pregnant workers who work with or around radiation. They help ensure the safety of both the declared pregnant worker and the unborn child by carefully monitoring any exposure to radiation.

The Standard Type 82 TLD-XBG badge or Type 83 TLD-XBGN badge for neutron should be worn close to the embryo/fetus to obtain the most accurate dose.

Benefit: Fetal Monitors are available for pregnant radiation workers to ensure the fetus does not exceed 500 mrem for the entire gestational period or exceed 50 mrem in a single month.

Handheld X-Ray Units: Dental Office Radiation Monitoring Requirements

X-rays are a daily occurrence for both staff and patients in the dentist office. For this reason, dental offices that make use of a handheld x-ray unit typically require radiation monitoring. When using handheld devices, safety is of the utmost importance. If an error or malfunction were to occur, it poses a greater safety risk to the worker than a conventional x-ray method. This greater risk is due to the fact that the workers cannot distance themselves from the device (as they can with a conventional dental x-ray method). 

While handheld devices typically feature a lower output dose rate, taking the necessary safety measures are crucial. 

In this article, we will discuss radiation safety in the dental office setting, protections & liability, available technology, and recommendations & solutions. 

The Importance of a Radiation Safety Program 

The main principle of radiation safety is referred to as “ALARA.” ALARA is an acronym that stands for “as low as reasonably achievable.” This means that the goal of a radiation safety program is to keep worker radiation doses as low as possible. 

A well-established radiation safety program provides credibility for the organization, while also providing employees with peace of mind. By monitoring both your employees and the area for radiation exposure, a hazardous situation can be quickly detected and acted on. 

If radiation monitoring (area and personnel) is not happening, you may not realize something is wrong with your x-ray machine. Without monitoring, it’s very difficult to ensure your employees are choosing the position of minimum exposure during patient treatment. 

To accomplish the goal of avoiding the hazards of radiation exposure, there are three basic protective tenets: 

Time: 

Time refers to how long personnel spend near a source of radiation. The amount of time should be minimized whenever possible, while still allowing the worker to accomplish necessary tasks. 

Distance: 

Distance refers to the proximity to a source of radiation. The distance should be maximized whenever possible, as increasing the distance leads to a decreased radiation dose. 

Shielding: 

Shielding refers to putting something between you and the source of radiation. Whether it be a wall, protective clothing, or other safety equipment. 

Materials that block radiation

For more information on the importance of a radiation safety program, please check out our recent article. “Radiation Safety Programs: A Comprehensive Guide.” 

Personnel workload optimization without the monitoring or tracking of who is receiving exposures (or using the number of X-rays taken) makes it hard to determine if workers are staying below the recommended number of X-rays per year (to ensure monitoring is not required). 

If workload is above 100 intraoral or 50 panoramic films per week it may be likely to exceed (100 mrem/year).

Protection Against Liability and Litigation 

From insights gathered, many dental office owners, managers, and dentists are reluctant to spend the funds towards radiation monitoring. While some may think it’s unimportant, others don’t see that a simple dosimetry solution can be easy. This creates a major concern for personnel throughout the industry. 

People who are diagnosed with cancer sometimes assume that the cancer was caused by occupational exposure (the radiation dose received in the workplace). Usually those in this situation are upset and are looking for someone to blame. In these instances, the employer generally should be able to provide the dose to any current or former employee that had a chance of being exposed to radiation, even if doses are low within the practice. 

A reading of “minimal” or low recorded doses becomes very important objective evidence down the road if someone were to be diagnosed with cancer. 

Those who have been involved in a radiological accident (machine or procedure malfunctioning) could become upset. They may think that they received additional dose due to radiation leakage. Flaws in head/applicator shielding, lack of appropriate head/applicator shielding, or an incorrectly positioned x-ray tube insert can lead to increased radiation leakage as well as the potential for increased out-of-field patient dose. 

With the increased use of Cone Beam CT (CBCT), the probability of this occurrence is markedly higher than in the past. 

Pregnant radiation workers who miscarry or those who give birth to disabled children may wonder if their occupational exposure could be the cause. For all the potential situations detailed above, proper monitoring can protect an employer against liability and litigation. 

In this way, a relatively small investment in monitoring for the organization can prevent the potential for a much larger capital expenditure down the road. 

Technological Advancements 

When used appropriately, digital x-ray equipment does provide less dose to the patient and users. However, if just switching from film to digital and not setting up the x-ray system to reduce the dose and x-ray energy, the dose reduction will not be realized. 

Studies indicate a potential dose reduction between 40-75% when switching from film to digital imaging. But additional studies indicate that the patient dose can vary up to a factor of 17 if the x-ray unit is not set up correctly for the new digital technique. 

The changing image capture settings used in Cone Beam CT units introduces a new radiation environment into the workplace. Monitoring should always be reevaluated when new technologies are deployed. 

Groups That Recommend Monitoring 

There are two main well-respected and recognized groups that recommend radiation monitoring in the dental office setting. These groups are the American Dental Association (ADA) Council on Scientific Affairs, and the International Dental Association (FDI). 

The NOMAD X-Ray Unit 

The Arizona Smile Center describes NOMAD x-ray units as, “A handheld, battery-powered intraoral x-ray system that produces high-quality radiographs with digital sensors and phosphor plates. Digital radiography (digital x-ray) is the latest x-ray technology used to take dental x-rays.” 

Intuitive User Interface 

The NOMAD x-ray unit utilizes the latest x-ray technology to both preserve the quality of your images and deliver exact and repeatable exposures with outstanding image quality. Its ergonomic design makes the device more stable in your palm (due to shape and weight dispersion). 

Efficient Workflow Advantages: Freedom 

Handheld x-ray units can result in more mobility. Which can lead to a greater potential of irradiation of coworkers (scatter radiation) than fixed units in confined spaces. However, a more relaxed radiation safety posture has been observed when these units are in use. This poses a threat to personnel. 

In dental settings, PSP or sensor modality are two common techniques for generating x-ray imagery. 

Photostimulable phosphor (PSP) plates are still very commonly used as receptors in intraoral radiography. PSP allows for indirect digital image acquisition. This means after the exposure, a latent image occurs on the plate, and it is then converted to a digital radiographic image via a scanning device. 

A digital intraoral sensor is a small device that is used to capture x-ray images. Instead of using a heavy vest to protect against radiation and being situated in a large intense machine, patients can remain in their exam chair while the sensor is inserted into their mouth. 

Handheld x-ray device

Solutions To Common Concerns Around Radiation Monitoring 

If the main concern is cost, we can switch personnel in an organization to a longer frequency (semiannual or annual), and potentially keep area monitors on a shorter frequency. The dosimeters on shorter frequency will have the ability to identify any unexpected situations. 

If the main concern is logistics, we can recommend the use of digital dosimeters, which do not need to be shipped back and forth. An added bonus to digital dosimeter usage is that the dose reports are very simple to understand, and any exceptions can be more easily highlighted.

The Evolution of Radiation Safety: A History of X-Ray Badges 

Since its discovery in 1895, radiation has revolutionized both science and medicine, although early researchers had no idea the dangers it presented. In this article, we’ll dive deeper into the history of radiation (including its discovery and major inventions), in addition to exploring the evolution of radiation safety practices such as x-ray badges. 

The Discovery of X-Rays and Radioactive Materials 

Wilhelm Conrad Röntgen 

On November 8, 1895, a German physicist named Wilhelm Conrad Röntgen was experimenting with electric current flow in a partially evacuated glass tube (cathode-ray tube). Röntgen observed that a screen of barium platinocyanide far away from the tube gave off light when the tube was operating. He theorized that when the cathode rays (electrons) struck the glass wall of the tube, some unknown radiation was formed. The unknown radiation then traveled across the room, struck the chemical, and caused the fluorescence. Later investigations revealed that other materials (including paper, wood, and aluminum) were transparent to this form of radiation. He mistakenly thought the rays were unrelated to light, and due to its uncertain nature, he called the phenomenon x-radiation. 

Röntgen took the first x-ray photographs of the interiors of metal objects and the bones in his wife’s hand. He did not patent his discovery (which also became known as Röntgen radiation), because he wanted his work to benefit all. In 1901, he received the first Nobel Prize for Physics for his work on x-ray radiation, and donated the money he received to the University of Würzburg (where he had accepted an honorary doctorate of medicine). The use of x-rays in medicine—for both medical imaging and the treatment of cancers—was almost immediate, happening only weeks after the announcement of Röntgen’s discovery in early 1896. 

Marie Curie 

Marie Curie shared the Nobel Prize for Physics in 1903 with Henri Becquerel for their contributions to the understanding of radioactivity. Working with her husband Pierre, they discovered polonium and radium. After her husband’s death, Marie’s devotion to developing the use of x-radiography only strengthened. She played an integral part in the completion of the laboratories at the Radium Institute at the University of Paris, which would go on to become a universal center for chemistry and nuclear physics. 

Marie Curie’s death by aplastic anemia in 1934 was caused by the action of the radiation she studied for over thirty years. Nevertheless, her influence in nuclear physics and chemistry was immense and impacted many generations to come.

Early Incidents of Radiation Exposure and Subsequent Dangers 

As we mentioned above with Marie Curie, many early pioneers in radiation research suffered severe health issues, with many cases resulting in death. Notable victims included Thomas Edison’s assistant, Clarence Dally, who ultimately lost both of his arms due to high levels of radiation exposure, and the “Radium Girls.” 

The “Radium Girls” were a group of female factory workers who painted watch dials with radioactive paint. Their work led to severe radiation poisoning in many workers, resulting in more than thirty deaths due to radiation exposure. These high-profile examples (media coverage and litigation for “The Radium Girls” was plentiful) led to the emergence of radiation protection regulations and guidelines. The formation of the International Commission on Radiological Protection (ICRP) in 1928—and later in the 1970s, national regulatory bodies like the US Nuclear Regulatory Commission (NRC) and the UK’s Health and Safety Executive (HSE)—proved to be vital steps to combat radiation exposure. 

Major Inventions in Radiation Protection and Safety 

Geiger-Müller Counter 

In 1928, Hans Geiger (a renowned German physicist) and Walther Müller (a PhD student of Geiger) developed the sealed Geiger–Müller tube. This small device used basic ionization principles to detect alpha and beta radiation as well as gamma radiation (which prior models had been unable to do). This practical instrument could be produced relatively cheaply, as the tube output required little electronic processing. Due to minimal valve count and low power consumption, the Geiger counter (as it became known) achieved great popularity as a portable radiation detector. To this day, the Geiger counter is a staple in many industries used to detect ionizing radiation. 

Scintillation Detectors 

A Scintillation Detector (or Scintillation Counter) is an instrument used to detect and measure ionizing radiation that uses the excitation effect of incident radiation on a scintillating material and detecting the resulting light pulses. The first electronic scintillation counter was invented in 1944 by Sir Samuel Curran at the University of California at Berkeley. A requirement to measure the radiation from small quantities of uranium birthed this innovation, which used the newly available and highly-sensitive photomultiplier tubes to accurately count the flashes of light from a scintillator subjected to radiation. 

Wearable Protection Equipment 

Shielding is one of the three main tenets of radiation safety (more on this below). Shielding relies heavily on the use of Personal Protective Equipment (PPE) for radiation protection, which includes lead aprons or vests, lead thyroid collars, lead gloves, and safety glasses (as the lens of the eye is one of the body’s most radiosensitive tissues). PPE is commonly used in settings where medical radiation is necessary. For more on this, please check out our guide on materials that block radiation.

Devices Used to Measure Radiation Dose 

Dosimeters, Including X-Ray Badges 

A radiation badge—also commonly called a personal dosimeter—is a device that measures the absorbed dose of ionizing radiation for personnel that are in occupational contact with radioactive material. Radiation monitoring badges are the main component of radiation dosimetry, which is the accurate and systematic measurement, calculation, and assessment of the ionizing radiation dose absorbed by matter or tissue. 

Dosimetry is broken into two branches: internal absorption and external radiation. X-ray badges are crucial to external radiation. The introduction of dosimeters was vital in the tracking of occupational radiation exposure, and subsequently improved workplace safety for radiation workers in various fields (including nuclear power plants). Normally those in contact with radioactive substances during the regular course of their employment (or those who have the potential to be exposed to radiation), carry personal x-ray badges somewhere on the outside of their clothing. Continued technological advancements and constant regulatory compliance are paramount to the safety of radiation personnel. 

Film X-Ray Badges 

The earliest form of personal dosimeters, film badges used photographic emulsion to measure radiation exposure. Early film x-ray badges were not very sensitive, and easily impacted by adverse environmental conditions like temperature and humidity. They also had to be exchanged every two weeks to be processed and analyzed. Results were recorded on index-sized cards called dosimetry cards. These cards were used to record an employee’s cumulative external exposure to radiation, and this process continued until the late 1970s. In 1979, an early computer system replaced dosimetry cards. Film badges were replaced in 1994 by Thermoluminescent Dosimeters (TLD). 

Thermoluminescent Dosimeters (TLDs) 

TLD dosimeters provided a more accurate and reliable measurement of occupational dose than their film badge predecessor. As ionizing radiation passes through a thermoluminescent dosimeter, electrons in the material are moved into dosimetric traps. The electrons are held there until the detector is heated up. Once the temperature reaches a maximum of approximately 400° Celsius, the trapped electrons begin to move. This movement causes a light pulse to be emitted, also known as luminescence.  

In luminescence, only a small fraction of atoms (called the emission center or luminescence center), emit light. A photomultiplier tube (PMT) is then used to count the visible light emitted. The amount of emitted light is proportional to the amount of ionizing radiation exposure that the dosimeter received. 

Optically Stimulated Luminescence (OSL) Dosimeters 

In 1998, Optically Stimulated Luminescence (OSL) Dosimeters were introduced. The material makeup of a TLD dosimeter and an OSL dosimeter is very similar, with both composed of crystalline solids. Both dosimeters capture point dose measurements, or radiation doses in a relatively small volume.  

An OSL dosimeter most commonly uses Beryllium Oxide (BeO) to absorb x-ray energy. It then releases it and measures the precise dose of ionizing radiation received. Beryllium Oxide is commonly used because it is extremely durable, sensitive, and resistant to environmental influences and fading. Some OSL dosimeters use Aluminum Oxide (Al2O3:C) instead of BeO. 

Electronic Dosimeters 

An electronic personal dosimeter provides a real-time direct display of information about the measured dose for the individual wearing the device. This real-time reading enhances radiation worker safety (ensuring levels don’t exceed body dose limit) and enables for a quicker response to potential hazards. 

The Revolution of Radiation Safety Practices 

The goal of any radiation safety program is to keep radiation doses as low as reasonably possible (“ALARA”). There are three basic protective measures to minimize radiation exposure are: 

  1. Time: Time refers to the duration spent near a radiation source. The amount of time should be minimized whenever possible, while of course still allowing the worker to accomplish necessary tasks. 
  2. Distance: Distance refers to the proximity to a radiation source. The amount of distance should be maximized whenever possible. Increasing distance leads to decreasing dose. 
  3. Shielding: Shielding refers to simply putting something between you and the radiation source (whether it be a wall, protective clothing, or other equipment to assist in proper shielding).

The Importance of Radiation Badges for Dental Offices 

When it comes to dentistry, x-rays are a daily occurrence for both staff and patients. To help keep your dental staff safe, it’s vital to measure their exposure to radiation. So long as you follow proper safety protocols, occupational exposure should be minimal. To ensure you’re managing exposure correctly, it’s vital to invest in radiation badges for dental offices that track exposure.

In this article, we will discuss the sources of radiation in dental offices, why radiation badges are important, which members of the staff should wear them, and best practices with respect to badge usage. 

Why Do You Need Radiation Badges for Dental Offices?

X-Ray Machines 

X-rays are the most common radiation type when it comes to ionizing radiation. These machines emit a small amount of ionizing radiation – on average between 0.5-1 mrem per image. A full-mouth x-ray series (which includes 18 to 20 images), usually only delivers a dose of about 10-20 mrem.

Cone Beam Computer Tomography (CBCT) 

CBCT emits a higher amount of radiation than traditional x-ray machines. These machines produce 3 dimensional images of teeth, gums, and other oral structures. On average, a CBCT scan delivers a dose of 20-60 mrem per scan.

Handheld Dental X-Ray Devices 

Handheld x-ray devices emit a lower amount of radiation than traditional x-ray machines. These devices take x-rays of individual teeth or small areas of the mouth. On average, a handheld x-ray device emits between 1-5 mrem per image. Handheld x-ray devices though pose some additional risk as personnel are not able to distance themselves during exposure and from that run a higher risk.

Curing Lights 

Curing lights emit a small amount of non-ionizing radiation. They are used to harden dental materials, such as fillings and sealants, and they typically emit less than 1 mrem per use. 

UV Lights 

UV lights also emit a small amount of non-ionizing radiation. They are sometimes used to detect oral cancer or other issues, and typically emit less than 1 mrem per use. 

Gamma Rays For Sterilization Of Extracted Teeth 

Gamma radiation has proven to be an efficient way to sterilize extracted teeth, as alterations of dentin and the enamel mechanical properties are minimal. 

Calculating Radiation Dose 

As we’ve read, there are numerous sources of radiation that dental workers can encounter which is why radiation badges for dental offices are critical for keeping them healthy. Radiation badges (also known as dosimeters) are recommended in dental offices to monitor the amount of radiation exposure over time that is received by personnel who work with ionizing radiation. While they are not always required, radiation badges for dental offices play a crucial role in employee safety, while also helping to minimize company liability. Responsibility for damage caused by exposure to radiation in the workplace is most often assigned to the employer. 

Employers utilizing sources of radiation in their business are regulated by the states for safe use. Exposure to hazardous radiation is governed by laws that are designed to protect employees through the safe handling and use of radioactive sources. Radiation damage experienced by employees is most often an indication of failing to abide by these laws, which leaves the employer exposed to legal liability for the damage caused.

Dosimeters And Radiation Safety 

Developing and implementing a radiation safety program – and maintaining improved dosimetry compliance – ensures that the documented occupational dose always remains within safe limits. This ultimately can assist employers in limiting their exposure to liability in the workplace. 

Minimizing radiation exposure also minimizes the risk of long-term health effects (like cancer and other radiation-induced illnesses). When it comes to radiation exposure, ALARA is the most important acronym to know. It stands for “as low as reasonably achievable,” which simply means that the goal of any radiation safety program is to keep radiation doses as low as reasonably possible.  

Who Should Wear Badges In A Dental Office Setting 

When deciding who should be wearing radiation badges for dental offices, it’s key to look at who faces the most exposure to radiation. Dentists and hygienists, as they are most likely to work directly with X-ray machines or CBCT scanners (which are the primary sources of ionizing radiation in a dental office),should wear dosimeter badges. Dental assistants should also wear them, as they may also work with these machines. Certain office staff – including any staff who handle or process x-ray film – as well as staff who work in the processing area, should also wear a badge to document radiation exposure and mitigate the risk. 

The Ins and Outs of Dosimeters 

For a deeper look into how badges should be handled, where they should be worn, where they should be stored when not in use, how to closely track exposure, simplifying dose reads, and more, please refer to our recent article, Dosimeter 101: Instructions on Radiation Badge Use

Why Pursue Lower Dose Thresholds – Who Benefits from Radiation Monitoring? 

Every employee monitored benefits from radiation monitoring, as they are able to work with peace of mind knowing that their health is not at risk. The company’s ownership is also a beneficiary, since documented occupational dose monitoring provides protection against current and future legal health claims by an employee (so long as the owner is able to show documented evidence that his/her employees did not exceed their occupational dose limits during their term of employment). For this reason, detailed dose records should be kept for the lifetime of the business. 

Providing workers with personal radiation dosimeter badges gives both the worker and employer peace of mind knowing that radiation exposure is constantly being monitored by a fully accredited dosimeter.

Who’s Who: 8 Radiation Companies Providing Dosimetry Solutions

Ionizing radiation is a danger in many occupational settings, which makes diversified solutions able to address potential exposure to radioactive material so crucial.  

Ionizing radiation is radiation consisting of particles, x-rays, or gamma rays (gamma radiation) with energy powerful enough to cause ionization in the medium through which it passes.  

In this article, we’ll take a deeper look at companies that offer quality radiation protection products and solutions.  

Companies Featuring Personal Radiation Dosimetry  

Radiation Detection Company  

Radiation Detection Company was founded in 1949 and is the longest operating dosimetry company in the world. Located in Georgetown, TX, centrally serving customers, RDC can deliver badges in as little as 2 days with their fully domestic supply chain and report turnaround in 10 days or less.

Dosimeter 101: Instructions on Radiation Badge Use  

Radiation badges are an incredibly important piece of occupational safety for many workers. It is crucial that guidelines are followed so that badges can provide the most accurate measures of radiation and ensure personnel safety. 

In this article we will take a deeper look at the steps that must be followed for the proper usage of radiation dosimeters. As always, we hope you find this article informative, and we look forward to hearing your feedback! 

Radiation Exposure Prevention 

Radiation badges do not directly protect workers from exposure. However, they are the main component of radiation dosimetry, which documents radiation dose. This ensures that each radiation worker can monitor their exposure limits and in doing so can avoid exceeding the allowable limits established by governing bodies.

An organization’s Radiation Safety Office is generally comprised of a qualified expert called a radiation safety officer (RSO), a management representative, and personnel who work with radiation-producing equipment or are otherwise at risk of occupational exposure. 

This office is responsible for the implementation, coordination, and supervision of a company’s radiation safety program. It is also tasked with ensuring that the organization is following all federal, state, and local regulations. The office has the authority to enforce radiation policies and procedures with respect to both radiation safety and regulatory compliance.

Adhere to the Radiation Safety Program 

As we detailed in our previous blog titled, “Radiation Safety Programs: A Comprehensive Guide,” an effective radiation safety program includes: 

  • A dosimetry program in which personal exposure monitoring is conducted as required by federal or state regulations. 
  • Surveys and area monitoring to document elevated radiation levels, contamination with radioactive materials, and potential occupational exposures. 
  • Radiological controls, including entry and exit controls, receiving, inventory control, storage, and disposal. 
  • Proper training for workers with respect to radiation protection, including the negative health effects associated with ionizing radiation dose. 
  • Emergency procedures to recognize and respond to radiological emergency situations. 
  • Accurate reporting to maintain all records and provide dosimetry reports and notifications. 
  • Internal procedures to audit all aspects of the radiation program annually to ensure adequate protection. 

General Rules for Dosimeter Badge Use 

  1. Only the person assigned a dosimetry badge should wear it (in other words, only wear a badge with your name on it). Do not give someone else your badge to use, and do not use it for monitoring an area (this is what area monitors are for). 
  1. A radiation dosimeter should be worn whenever there is a possibility of exposure to ionizing radiation (i.e. gamma radiation, x-rays, etc.) during the workday. 
  1. The badge should be worn such that monitoring is optimized during the wear period (more on this below under “How to Wear Each Type of Badge”). Dosimeters should always be turned to face the source of radiation. 
  1. Dosimeters that aren’t being used should never leave the workplace. They should be stored in a safe area with low background radiation when not in use. Avoid storing in areas with high temperatures and high humidity. 
  1. Do not lose or damage badges. Report missing, lost, or damaged badges promptly to your badge coordinator or your Radiation Safety Office. 
  1. Your badge will usually be exchanged monthly or quarterly based on risk (more on this below). It is important that you return your badge on time at the end of each monitoring period. 
  1. If you wear a lead apron, the badge must be worn over top of the apron, not underneath it. Some exceptions to this rule is the “fetal monitor,” which is worn in the abdominal area and underneath the lead, or an EDE or Webster calculations.

How Often Should Dosimeters Be Exchanged? 

Generally, dosimeter badges are exchanged on a monthly or quarterly basis. How frequently a badge needs to be exchanged depends on the risk of exposure in the specific workplace (higher risk means more frequent exchanges).

Control Badges & the Exchange Process 

A control dosimeter is issued with every group of dosimetry badges sent to an organization. This control badge helps determine background radiation exposure, and captures any exposures to the shipment of badges during transit. 

The control must be stored away from any radiation source to avoid picking up exposure. For more on this, please refer to our blog, “8 Must-Know Facts About Control Dosimeters.” 

Lost or Damaged Monitoring Badges 

If a badge is lost or damaged, it’s crucial that this is reported to your radiation safety office immediately so the issue can be addressed, and a new badge can be ordered or given to you. 

Reviewing Dose Reports 

Each radiation badge will contribute to a dose report. The analysis of the badge results in the legal dose of record. Dose reports also contain a wide array of data for review by an organization’s Radiation Safety Office. These reports provide detailed information needed to maintain a compliant program at the federal, state, and local levels. 

Dose reports also track each worker’s cumulative radiation dose throughout the year. This is important as it sheds light on how close an employee’s dose is to the annual applicable radiation dose limit as well as any ALARA notifications (as-low-as-reasonably-achievable as a worker should stay within safe dose limits.

How To Wear Different Types of Badges 

Whole Body Dosimeter 

For the purposes of external radiation exposure, “whole body” is considered to be the head, torso, arms above the elbow, or legs above the knee. These badges are generally worn on the whole body location receiving the highest radiation dose, collar, waist, or torso, with the label facing the source of the radiation. 

Ring Dosimeter 

Ring dosimeters should be worn when there is a possibility of significant exposure to the hand. It is important to wear ring dosimeters on whichever hand has the highest exposure. Sometimes meaning a ring might be worn on both hands to more accurately measure exposure. Ring dosimeters should be worn under gloves to eliminate the risk of contamination. 

Wrist Dosimeter 

A wrist badge is fitted with a velcro strap which allows it to be worn around the wrist. The wrist badge is used for radiation workers whose arms may receive a higher exposure and could also be due to safety issues or dexterity problems. 

Fetal Monitors 

Fetal Monitors are available for pregnant radiation workers to ensure the fetus does not exceed the allowable limit for the entire gestational period. These badges should be worn close to the embryo/fetus to ensure the most accurate dose is obtained.

What if Badges Aren’t Required, But You Want To Wear One? 

If you happen to work in an environment where the potential for some radiation exposure exists but monitoring is not required, you can request monitoring equipment. 

Be sure to connect with your organization’s Radiation Safety Office or officer to discuss your safety concerns, and they can assist with solutions.

Radiation Badges To Use Based On Your Specific Work Needs 

There are many different types of dosimeters on the market these days. Specialization has allowed for some dosimeters to make more sense than others based on needs present in the workplace. In this article, we’ll review the purpose and benefit of different types of dosimeters, and why you should consider using them for your organization. 

We hope you find this article informative, and as always, we look forward to hearing your feedback! 

What Is Ionizing Radiation? 

Ionizing radiation is a form of energy that causes the removal of electrons from atoms and molecules of materials. Ionizing radiation is able to travel unseen and passes freely through these materials in the form of waves or particles. There are five types of ionizing radiation: alpha particles, beta particles, neutrons, gamma rays (gamma radiation), and x-rays (electromagnetic radiation). 

Minimizing Radiation Exposure 

Radiation protection is critical to those working in environments where ionizing radiation is present. Minimizing radiation exposure is paramount to the safety of such workers. For this reason, the US Nuclear Regulatory Commission (NRC) established dose limits for occupational exposure for people working with radioactive material or ionizing radiation (i.e. x-ray imaging equipment and external beam radiation therapy). This dose limit functions as a form of radiation protection for personnel monitoring. It also helps prevent the possibility of a radiation incident. Be sure to work with your organization’s radiation safety office to ensure you’re following your company’s radiation safety program to help minimize exposure. 

How To Measure Radiation Dose 

Normally those in contact with radioactive substances during the regular course of their employment (or those who have the potential to be exposed to radiation), carry personal dosimeters. These dosimeters are specifically designed to record and indicate a measure of the accumulated dose absorbed by the person. 

Types of Radiation Dosimeters 

Active Dosimeter vs. Passive Dosimeter 

Active dosimeters measure instantaneous doses, provide a visual indication which can alert attention to possible exposure, and follow the variations of radiation exposure over time. Personal radiation detectors – like electronic personal dosimeters (EPD), personal emergency radiation detectors, and a quartz fiber dosimeter – play a major role in active dosimetry, as active dosimeters generally require an external source of energy to operate. An electronic personal dosimeter provides a real-time direct display of information about the measured dose for the individual wearing the device. 

Passive dosimeters do not need an external source of energy to operate. They are also known as integrating dosimeters, which means they only give an estimate of the cumulative dose. Passive dosimeters record how much radiation an individual is exposed to over a specific period of time (i.e. a week, month, quarter, or year). 

Passive dosimeters are preferred in hospital settings and locations where occupational radiation workers are frequently exposed to low levels of radiation. These instruments are called “passive” dosimeters because they do not need to be continuously monitored. 

TLD Badge

TLD Badges vs. OSL Badges 

Thermoluminescent dosimeters (TLD) and Optically Stimulated Luminescent dosimeters (OSL) are the two primary types of radiation dosimeter used in passive dosimetry. While both Thermoluminescent dosimeters (TLD) and Optically Stimulated Luminescent dosimeters (OSL) measure dose level, their main difference is optically stimulated luminescence requires only light stimulation, while a TLD requires heat in order to stimulate the detector. 

For more on the differences between and features of TLD and OSL dosimeters, please check out our recent blog titled, “TLD vs. OSL Dosimeter – Instruments of Passive Dosimetry.” 

TLD Whole Body 

Purpose: Our Standard Type 82 TLD-XBG badge or Type 83 TLD-XBGN badge for neutrons are used to monitor occupational exposure to a single individual working with radioactive materials. “Whole body” is considered to be the head, torso, arms above the elbow, or legs above the knee. 

Benefit: TLD whole body dosimeters have been a trusted technology for decades and are still highly effeicient today. 

OSL Whole Body 

Purpose: Like whole body TLD badges, OSL badges are generally worn on the collar, waist, or torso, with the label facing the source of the radiation. 

Benefit: A major benefit is OSL dosimeters provide for the possibility of repeated readout. This means that OSL dosimeters are often archived for multiple years and can be re-read, as the dose does not fade. OSL dosimeters can also be read with light (unlike a TLD dosimeter which must be heated), which helps simplify the design. Their low dose rate sensitivity is also a benefit. Finally, OSL dosimeters are not impacted by heat or water.  

OSL badge
Ring Badge 

Purpose: Our TLD-XBG Extremity ring badge is available for radiation workers whose job functions potentially require their arms, legs, hands, feet, fingers, and toes  to receive a higher exposure. 

Benefit: Ring badges can be used by veterinarians taking x-rays – i.e. having to hold the animal down during the exam. Accurately assesses personal dose equivalent at the site where it’s worn. 

Wrist Badge 

Purpose: Our Standard Type 82 TLD-XBG badge or Type 83 TLD-XBGN badge for neutron is fitted with a velcro strap to be worn around the wrist. The wrist badge is available for radiation workers whose arms may receive a higher exposure, used due to dexterity issues, or even safety reasons. 

Benefit: Wrist badges are a viable alternative to ring badges, especially in nuclear medicine where the dose distribution on different locations of the hand differs. 

Fetal Monitoring Badge 

Purpose: Our Standard Type 82 TLD-XBG badge or Type 83 TLD-XBGN badge for neutron should be worn close to the embryo/fetus to obtain the most accurate dose. 

Benefit: Fetal Monitors are available for pregnant radiation workers to ensure the fetus does not exceed 500 mrem for the entire gestational period or 50 mrem in a month. 

Area TLD 

Purpose: Area Monitors can be used to ensure that the public is not being exposed to more than 100 mrem/year from outside a room/building. 

Benefit: Monitors potential exposure to the public, as it is the responsibility of the company to prove that the public is not being exposed to more than the allowable dose limits.  Area Monitors can also be used to monitor occupational dose to employees in a room where the radiation source is located (or a room near a source, or dangerous radiation zone).
