Who must approve a pregnant worker entering radiological zones?

• A. HR
• B. RHP or delegate
• C. Health Physics
• D. Supervisor

Answer: (B)

Pregnant workers entering radiological zones must be approved by the Radiation Health Professional (RHP) or their delegate because protecting the fetus requires specialized radiological risk assessment and control. The RHP assesses potential doses in the planned work, ensures monitoring and shielding are adequate, applies ALARA principles, and can authorize or restrict access with appropriate protections. HR handles personnel issues, and while Health Physics is the broader field, the specific approval to enter controlled areas during pregnancy rests with the RHP or their delegated authority, who has the training and authority to balance operational needs with fetal dose safety. The supervisor can implement the approved plan, but the final authorization comes from the RHP or delegate.
