If wearing a lead apron, where should the dosimetry badge be placed?

• A. Attached to scrubs behind the lead apron
• B. Attached to scrubs in front of the lead apron
• C. On the sleeve of the shirt
• D. On the hard hat

Answer: (A)

The main idea is to monitor the radiation dose that actually reaches the worker when protective gear is used. A lead apron blocks much of the primary beam, so the badge should be placed where it will record the exposure that gets around or behind the shield rather than being shielded by it. Placing the dosimetry badge on the scrubs behind the lead apron positions it to capture the dose from scatter or leakage that can affect the wearer despite the apron, providing a better reflection of real occupational exposure in typical procedures. Therefore, attaching the badge behind the lead apron aligns with the goal of measuring the true exposure experienced by the wearer.
