If dosimeter is lost, alarming, damaged, or isn't working you should ...

• A. Leave the area and notify RP
• B. Continue working
• C. Reset the dosimeter
• D. Ignore alarm

Answer: (A)

When a dosimeter is compromised, the safety rule is to stop work and get it checked. The dosimeter records your radiation exposure, and if it’s lost, alarming, damaged, or not functioning, you can’t rely on its readings. Leaving the area reduces potential additional exposure, and notifying Radiation Protection (RP) ensures a replacement dosimeter is issued, your dose is assessed, and your records stay accurate. Resetting the device isn’t appropriate because it can hide a fault, and ignoring the alarm or continuing work with a faulty monitor removes essential safety feedback and increases risk. In practice, move to a safe location and inform your supervisor and RP, then await a replacement and further instructions.
