Pregnant workers may request an additional badge for monitoring doses underneath what?

• A. Underneath lead aprons
• B. On gloves
• C. On the collar
• D. Over lead aprons

Answer: (A)

The essential idea is to monitor the fetus’s exposure by adding a second dosimeter placed where it can accurately measure dose to the abdomen. When a pregnant worker wears a lead apron, the apron shields the torso, so putting an extra badge underneath the apron captures the amount of radiation reaching the abdomen (and thus the fetus) despite the shielding. This helps ensure fetal exposure stays within recommended limits.

A badge worn on the collar would reflect exposure to the head and thyroid, not the fetus. A badge on the gloves isn’t useful for monitoring fetal dose, and a badge over the lead apron wouldn’t accurately represent the dose reaching the abdomen because the apron would partly shield it.
