If a fixed area gamma monitor (FAGM) alarms in your work area, which action should you take first?

• A. Check EPD
• B. Place work in a safe area and leave
• C. Notify RPC or supervisor
• D. Do not re-enter unless given approval

Answer: (B)

When a fixed area gamma monitor alarms, the immediate priority is protecting yourself from radiation exposure. The best first action is to place your work in a safe area and leave the area. This minimizes your time in the elevated radiation field and increases distance from the source, which is the quickest way to reduce exposure in an abnormal situation.

After you’ve safely left, report the alarm to the RPC or your supervisor so they can assess the situation, coordinate any further actions, and determine whether and when re-entry is allowed. Do not re-enter unless you have explicit approval. Related checks, like reviewing dosimetry or equipment status, come after you’ve moved to safety and notified the appropriate supervisor.
