After radiopharmaceutical treatment, which action is required?

• A. Notify your supervisor
• B. Cannot enter zoned or unzoned areas or participate in the dosimetry program
• C. Stay clear of various radiation instruments, dosimeters, and avoid submitting bioassay samples until approved by Health Physics
• D. Return to work immediately

Answer: (C)

After radiopharmaceutical treatment, there can be residual radiation and contamination concerns that require formal clearance before you resume normal work activities. Waiting for approval from Health Physics before handling dosimeters, entering certain radiation-associated equipment areas, or submitting bioassay samples helps ensure that monitoring data remain accurate and that any remaining activity is properly managed and documented. This protects both you and others by making sure all safety checks and decontamination steps are completed before you re-engage in routine duties.

Notifying your supervisor is important, but it doesn’t replace the need for Health Physics clearance. Returning to work immediately would ignore safety controls, and trying to access instruments or dosimetry programs or zones without approval could compromise safety and monitoring.
