A bioassay system and WBC count is required to:

• A. Become Dose Management System Active Before Any Radiological Work Is Performed
• B. Prior To Performing Red Work At Any Non-OPG Facility
• C. As Directed By RHP, DHP Or RPC
• D. To Be Made Dose Management System Inactive When Radiologic Work Is No Longer Required

Answer: (A)

Before any radiological work begins, the dose management system is activated by establishing a baseline health and contamination status. A bioassay checks for internal contamination by detecting radioactive material in the body, usually through urine samples, while a white blood cell count provides a hematologic baseline to catch early radiation effects on the bone marrow. Together, these tests ensure that dose tracking starts from a known point and that any internal exposure is identified promptly, so the worker’s safety can be monitored throughout the job. The other options don’t fit because activation is a prerequisite for proper monitoring (not just guidance from others), it isn’t about performing work at non-OPG facilities specifically, and turning the system off after work ends would defeat the purpose of ongoing dose surveillance.
