If your dosimeter is lost, alarming for any reason, damaged, or isn't working, you should?

• A. Leave the area and notify RP
• B. Continue working and report later
• C. Ignore until the end of the shift
• D. Reset the dosimeter and continue

Answer: (A)

When a dosimeter is lost, alarming, damaged, or not working, you must stop work and leave the area and report to Radiation Protection (RP) immediately. The dosimeter is the official record of your external radiation exposure, and if it’s compromised you can’t verify how much exposure you’ve received. Promptly reporting to RP allows them to assign a replacement dosimeter, assess the potential exposure, and update your dose record as needed. They may also provide guidance on any necessary medical monitoring or corrective actions and ensure regulatory compliance. Do not continue working, do not ignore the issue, and do not reset the device.
