During AF operations, how many dosimeters should be worn?

• A. Only assigned dosimeter during AF operations.
• B. Rotate dosimeters daily.
• C. Wear all dosimeters available.
• D. Wear the oldest dosimeter.

Answer: (A)

In AF operations, one dosimeter is assigned to each person to accurately track that individual’s occupational exposure and link it to their personnel dose record. Wearing only the assigned dosimeter ensures the dose measurement belongs to you, stays consistent in your records, and avoids confusion or double counting that could come from using multiple devices. Rotating dosimeters, wearing all of them, or favoring the oldest one would make the exposure data unreliable or misleading. The assigned dosimeter is the one that reflects your true exposure during the operation, so that’s the correct practice.
