Where should the dosimeters be worn according to the policy?

• A. On The Trunk
• B. On The Head
• C. On The Leg
• D. On The Wrist

Answer: (A)

Dosimeters are placed on the trunk because this position best represents the whole-body exposure a person would receive. The chest area sits near the body's center of mass and stays relatively consistent despite clothing and movement, giving a reliable, conservative reading of the dose to most organs. Putting a dosimeter on the head would reflect head exposure, not the whole body; on the leg or wrist would measure limb exposure, which can vary and isn’t the standard for whole-body monitoring. For these reasons, the policy specifies wearing the dosimeters on the trunk.
