Radiation shielding utilized in medical offices is essential to ensuring the safety and well-being of patients and staff. With the growing use of X-rays, nuclear medicine, and other diagnostic imaging techniques, selecting suitable materials to block radiation and protect individuals from potential harm is crucial.
What is Radiation?
Radiation is a form of energy emitted by unstable atoms as they decay or transform into more stable forms. There are two main types of radiation: ionizing and non-ionizing. Ionizing radiation includes alpha, beta, gamma, and X-rays, while non-ionizing radiation comprises radio waves, microwaves, and visible light.
Ionizing radiation is particularly hazardous because it has enough energy to ionize atoms, potentially causing damage to DNA and other molecules within cells. This damage can lead to mutations, cancer, organ failure, and other severe health issues. As a result, it is crucial to protect individuals from excessive exposure to ionizing radiation.
Types of Radiation Shielding Materials
Traditional Lead (Pb) Shielding
Many medical offices utilize lead in their shielding with garments, shielding, and lead-lined walls. Lead is a dense, soft, and corrosion-resistant material widely used as a radiation shield for many years. Its high density makes it an effective barrier against X-rays and gamma rays. However, lead is not as effective in blocking alpha and beta radiation. Lead shielding materials are available in various forms, such as aprons, blankets, sheets, and bricks, and offer different levels of protection depending on the thickness.
Lead Composite Shielding
Lead composite materials combine lead and other lighter metals, such as tin, rubber, PVC vinyl, and proprietary attenuating metals (these materials may be reinforced with barriers). These materials are lighter (up to 25%) than traditional lead shielding and offer similar levels of protection. Lead composite shielding is available in garments such as aprons, vests, skirts, thyroid collars, and sheets. Always check with your RSO and contractor to ensure the correct materials are used.
Non-Lead (Pb) and Lead-Free Shielding
Non-lead and lead-free shielding materials are an environmentally friendly and recyclable alternative to traditional lead-based materials. These materials are composed of heavy metals, such as tin (Sn), antimony (Sb), tungsten (W), and bismuth (Bi), which absorb or block radiation. Non-lead shielding materials offer similar levels of protection as lead-based materials and are available in garments, sheets, bricks, and other forms.
Selecting the Right Radiation Shielding Material
Choosing the suitable radiation shielding material for the medical office depends on several factors, including the type of radiation present, the frequency and duration of exposure, and the specific procedures performed. Here are some tips to help make an informed decision:
Assess the Type and Level of Radiation Exposure
Determine the types of radiation in the medical office and the levels of exposure that staff and patients may experience. Then, consult a radiation safety officer or physicist to select the appropriate shielding material for specific needs.
Consider the Frequency and Duration of Procedures
The frequency and duration of ionizing radiation procedures will impact the type of shielding material needed. For example, if the medical office frequently performs X-rays or other diagnostic imaging procedures, it may require a more robust and durable shielding material.
Evaluate the Comfort and Ease of Use
Comfort and ease of use are critical factors when selecting radiation shielding materials, particularly for staff-worn garments. Lightweight materials, such as lead composite or non-lead shielding, can be more comfortable and easier to wear than lead-based materials.
Factor in Environmental and Disposal Concerns
Lead is a hazardous substance that requires special disposal precautions. If environmental concerns are a priority for the medical office, consider using non-lead or lead-free shielding materials, as they are recyclable and safe for non-hazardous disposal.
Radiation Shielding Applications in Medical Offices
Radiation shielding materials can be used in various applications within medical offices to protect staff and patients from ionizing radiation exposure. Some typical applications include:
Diagnostic Imaging
X-rays, computed tomography (CT) scans, and other diagnostic imaging procedures often involve ionizing radiation. Therefore, ensuring that both patients and technicians have proper protection is essential. Lead aprons, vests, and thyroid collars can protect against direct and scatter radiation during imaging procedures.
Nuclear Medicine
Nuclear medicine involves the use of radioactive isotopes for diagnostic and therapeutic purposes. Therefore, proper shielding is necessary to protect staff and patients from radiation exposure. Lead-lined storage containers, syringe shields, and waste disposal containers can minimize the risk of contamination.
Radiation Therapy
Radiation therapy uses high-energy ionizing radiation to treat cancer and other diseases. Therefore, appropriate shielding is crucial to protect patients and staff from exposure. Lead shielding materials, including aprons and thyroid collars, can help protect individuals during treatment.
Dental Offices
Dental offices often use X-rays for diagnostic purposes, requiring patient and staff protection. Lead aprons, thyroid collars, and lead-lined walls or partitions can help minimize radiation exposure in dental settings.
Implementing a Radiation Protection Program
Developing and implementing a radiation protection program is an essential best practice for protecting workers from ionizing radiation. A radiation protection program may include the following:
Designation of a Radiation Safety Officer (RSO)
An RSO is a qualified expert, such as a health physicist, responsible for overseeing and managing a medical office’s radiation protection policies and procedures. As always, for any specific questions about shielding or dosimeter badge use, always check with your RSO.
Establishment of a Radiation Safety Committee
A radiation safety committee should include the RSO, a management representative, and workers who work with radiation-producing equipment, radiation sources, or radioactive materials.
Equipment Registration and Licensing
Ensure radiation-producing equipment and radiation sources are registered and licensed according to federal and state regulatory requirements.
Implement a personal dosimetry program to monitor and record radiation exposure levels for staff working with ionizing radiation. Radiationsafety.com offers the best prices along with the most accurate technology.

Knowing how to wear a dosimeter badge & ring could make the difference in your safety. Working with ionizing radiation can be hazardous without proper dose tracking and monitoring. Therefore, it is essential for medical device operators and individuals working in environments with radioactive materials or devices emitting ionizing radiation to be proactive and diligent about wearing their dosimeters correctly. We will discuss the importance of wearing a dosimeter badge, different types of dosimeters, how to wear them correctly, and best practices for ensuring safety while working with ionizing radiation.
Importance of Wearing a Dosimeter Badge
Wearing a radiation dosimeter badge is crucial for anyone working with or near radioactive materials or devices that emit X-ray radiation. Regular exposure to ionizing radiation can harm one’s health if not appropriately monitored. Dosimeter badges help ensure that employees do not exceed the radiation limits set by federal guidelines and state regulations. In addition, by accurately recording exposure levels, dosimeters can provide valuable information to the Radiation Safety Officer, helping keep employees safe.
Types of Radiation Dosimeters
Various dosimeters are available for monitoring radiation exposure, including whole-body and ring dosimeters. However, we suggest 4-element OSL XBG badges for most uses.
Whole-Body Dosimeters
Whole-body dosimeters are issued to monitor radiation exposure to the head and torso. These dosimeters are sensitive to all types of ionizing radiation that can cause external exposure.
Ring dosimeters are issued to monitor radiation exposure to the hands. They are beneficial for employees working with X-ray radiation or low-energy isotopes, where specific extremities may receive elevated exposure.
Applying for Radiation Dosimetry
An application for personal dosimetry must be submitted to the Radiation Safety Office before dosimetry will be issued. The application process ensures that individuals working in environments with radiation exposure are provided with the appropriate radiation dosimeters to monitor their dose levels accurately. If you don’t have an RSO assigned to your company, identify one person who will be trained and administrate the account. Check OSHA and state regulations on becoming an RSO.
Dosimeter Exchange Frequency and Process
Radiation Dosimeters are issued for either a one-month or three-month wear period. At the end of the wear period, replacement dosimeters will be distributed through the designated badge coordinator. Dosimeter holders are reused and should not be returned with the used dosimeter.
Radiation Exposure Reports
The dosimeter vendor issues Radiation exposure reports, listing each individual and the exposure recorded. The Radiation Safety Office keeps these reports for review and inspection by regulatory agencies. Employees have the right to know their measured radiation exposure at any time. Annual reports are issued to each individual for their records.
Lost or Damaged Dosimeters
If a dosimeter is lost or damaged, it is crucial to report this promptly to the badge coordinator or the Radiation Safety Office so that a replacement dosimeter can be issued. In addition, maintaining accurate records of radiation exposure is vital for ensuring safety and compliance with regulations.
Pregnant employees should wear both a chest dosimeter and a fetal dosimeter. Even if the chest dosimeter is exchanged quarterly, the fetal dosimeter must be exchanged monthly.
How to Wear a Dosimeter Badge
Properly wearing a dosimeter badge is essential for accurate radiation dose monitoring. The following guidelines provide information on how to wear different types of dosimeters:
Chest
- Without apron: midway on the torso between shoulders and waist on either side of the chest
- With apron: outside the lead apron at shoulder level on either side of the chest
Collar
- Without an apron: on either side of a collar facing the radiation source
- With apron: outside the apron at collar level facing the radiation source
Collar & Waist
In some radiation environments, two dosimeters may be required. In such cases, one is worn at the collar and waist.
- With apron:
- Collar: outside the apron at collar level facing the radiation source
- Waist: either side of the waist, under the apron
Fetal & Chest
For pregnant employees:
- Without apron:
- Chest: either side of the chest
- Fetal: waist level on either side
- With apron:
- Chest: outside the apron on either side of the chest
- Fetal: centered on the waist, under the apron
Finger
Ring dosimeters are suitable for dose monitoring when providing radiation services on extremities.
- On one hand or both hands
- Label facing the radiation source
It is important to note that ring dosimeters are labeled for either left or right-hand use, so be sure to check before wearing.
Dosimeters Do Not Provide Protection
Dosimeters do not protect employees from radiation. Instead, their purpose is to document radiation exposure and ensure compliance with annual dose limits.
Dosimeters Help Create a Safe Work Environment
Dosimeter badges provide valuable insight into the safety of the work environment and the radiation levels in that area. Wear the badge daily and store it in a location free from radiation exposure while not removing it from the workplace.
Best Badge Placement Location
The optimal place to wear the badge is on the neck or chest, facing the radiation source. If wearing a lead apron, the badge should be worn over it, not underneath it. For pregnant employees, the badge should be worn on the abdominal area and beneath the apron. Contact your RSO for more information.
Avoid Borrowing Badges
Avoid borrowing or loaning dosimeter badges. Instead, employees should always wear the badge with their name on it.
Missing or Damaged Badges
Report missing or damaged badges immediately and obtain a replacement immediately.

What is a dosimeter badge or radiation detection badge?
What is a dosimeter or radiation detection badge? A radiation dosimeter badge, also known as an x-ray badge, are used by hospitals, labs, govt facilities, dentist, and vets. The passive dosimeter badge measures your radiation exposure from scatter ionizing radiation. The dosimeter badge identifies different radiation types, such as high-energy gamma, beta, or X-ray radiation. However, it cannot pick up on low-energy radiation from isotopes such as carbon-14, sulfur-35, or tritium1.
Radiation dosimeter badges do not protect you from radiation. Passive dosimeters calculate your total occupational radiation exposure so that your exposure stays within safe limits. The Environmental Protection Agency (EPA) outlines radiation thresholds above which radiation can become dangerous. These guidelines recommend radiation not exceeding 100 millisieverts (10 rem)2. Badges can help to ensure that your exposure does not exceed this amount.
This article will discuss the benefits of knowing your radiation exposure and how such information can help keep you safe at work.
Why should you wear a radiation detection badge?
Radiation can harm our tissues, primarily affecting our genetic material known as DNA. It damages DNA by breaking important bonds and water molecules in and around our DNA. When this occurs, free radicals are released. Free radicals are substances that can seriously injure your cells and organs3. Radiation is particularly harmful at higher doses. Though we receive low doses of radiation from our natural environment, we can also expose ourselves to radiation on the job. When exposed to radiation on the job, tracking your radiation dose to ensure that it is within safe limits is essential. High radiation doses increase your likelihood of radiation-associated health risks. For example, high radiation exposure has been linked to:
Wearing a radiation detection badge can also give you peace of mind that you are not putting yourself at risk while at work. For example, operating fluoroscopy units or X-ray machines may expose you to high-energy radiation. Likewise, you may be worried about the risks associated with your job and how your work may affect your cancer risk or other complications.
By wearing a radiation detection badge, you can know the amount of radiation you or your employees are exposed to while working. Having your employees wear badges helps minimize potential fraudulent lawsuits, as many healthcare workers who get cancer direct it back to radiation exposure in the workplace. Radiation detection badges do not just give peace of mind to employees who work around radiation but also to their employers. By utilizing badges and monitoring radiation appropriately, the likelihood of illness due to radiation exposure is low. When radiation is within safe limits, employees will be less likely to develop complications due to their work. Therefore, they will be less likely to sue their employer for a hazardous workplace. Additionally, having employees wear radiation detection badges ensures the employer does their due diligence to keep their workers safe.Order your x-ray badges today!

What is a TLD dosimeter? Dosimetry is the process of measuring radiation. Multiple instruments are available that detect and measure the presence of radiation in a laboratory, handheld or worn, like a dosimeter badge or ring from RadiationSafety.com.
When ionizing radiation loosens electrons, phosphor crystals in a dosimeter or dosimetry badge capture and store them. When those crystals are exposed to heat, they emit light as the electrons are released from the crystals, which illuminates a light on a dosimeter badge, band, or ring. That light is later measured and processed to provide a precise amount of radiation to which the dosimeter was exposed. When the dosimeter badge, band, or ring is worn over a period of time, anywhere from one to three months, the crystals can then be used to determine how much exposure the wearer has had over that period. This process is known as dosimetry.
A TLD dosimeter, or thermoluminescent dosimeter, is a passive radiation dosimeter that measures ionizing radiation. Ionizing radiation is caused by X-rays, gamma rays, beta particles, alpha particles, and other radioactive isotopes that carry enough energy to free electrons from their orbit around normally stable molecules. While this can cause damage to cells in living tissue, it also can be captured and measured in a well-designed environment, like in a dosimetry badge. In addition, ionizing radiation causes damage over time, so monitoring, limiting, and controlling how much a person is exposed to is essential.
Invented by Professor Farringon Daniels of the University of Wisconsin-Madison in 1954, the TLD dosimeter requires heat to function. They are most useful for situations where information about radiation amounts must be precise but not immediately required. TLD dosimeters can measure accumulated dosages to monitor potential health impacts.
A better alternative to TLD dosimeter badges is OSL XBG dosimeter badges.
Pros and Cons of TLD Dosimeters
Pros
- TLD dosimeters measure a large range of doses over a period of time.
- TLD dosimeters are typically the same price or even higher than OSL technology.
Cons
- TLD dosimeters require heat to function.
- Only one dose can be read at a time.
- Once the dose is read, it resets the dosimeter.
- One of the largest manufacturers of TLD badges and readers quit servicing their machines.
- TLD dosimeter badges tend to have a higher rate of “fade” than OSL badges.
RadationSafety.com provides radiation badges and rings that are affordable and unobtrusive. They utilize optically stimulated luminescence OSL technology, a more advanced technology than TLD dosimeters. OSL dosimeter badges are the industry standard used by the government, hospitals, labs, and companies worldwide. An OSL dosimeter works similarly to a TLD dosimeter, but an OSL dosimeter only requires optical stimulation, whereas a TLD dosimeter requires heat to function. These small and discrete radiation badges can be worn on your lapel and are designed to detect X-rays, gamma radiation, and beta particles, with neutron monitoring available for an additional fee.
