Who is required to wear personal dosimetry devices?

• A. Anyone that undergoes a procedure involving ionizing radiation
• B. Only radiologic technologists
• C. Anyone employed in a healthcare facility
• D. Anyone that is exposed to ionizing radiation as a part of their occupation

Answer: (D)

Personal dosimeters are used to monitor how much ionizing radiation a worker receives on the job. They’re part of a radiation protection program to keep occupational exposure within regulatory limits and to guide shielding, shielding placement, and work practices.

Because the devices are for tracking exposure tied to work duties, they are required for anyone whose job involves being around ionizing radiation as part of their occupation. Patients undergoing procedures don’t wear dosimeters because their exposure isn’t being monitored for occupational safety, and many healthcare workers have no exposure risk at all. While radiologic technologists are common wearers, other staff in radiology, nuclear medicine, interventional suites, and similar roles also need dosimeters when exposure is possible. Simply being employed in a healthcare facility isn’t enough to require a dosimeter if there’s no potential exposure to radiation.

So, the best guidance is: anyone who is exposed to ionizing radiation as part of their occupation should wear personal dosimetry devices.
