Pregnant workers entering Zones 2, Zone 3, or unzoned areas must wear a DCD when performing radioactive work or entering restricted areas. Which statement is correct?

• A. Only in Zone 1
• B. Only during non-radioactive tasks
• C. Only when not pregnant
• D. Yes, they must wear a DCD when entering Zones 2, Zone 3, or unzoned areas

Answer: (D)

The important idea is protecting a developing fetus from radiation exposure. In Zones 2, Zone 3, and unzoned areas, there is still potential for exposure when doing radioactive work or entering restricted areas. A DCD is used to limit and monitor the dose to the fetus, so pregnant workers must wear it in those areas during radioactive tasks or when entering restricted zones.

That’s why the correct statement is that they must wear a DCD in Zones 2, Zone 3, or unzoned areas. The other options would narrow the requirement incorrectly—only Zone 1, only during non-radioactive tasks, or only when not pregnant—which doesn’t align with the protection needed for pregnant workers.
