What is the primary purpose of the Dosimetry Program?

• A. Monitor only external exposures.
• B. To monitor occupational radiation exposures, including internal and external exposures, but not NORM or medical exposures.
• C. Track chemical exposures.
• D. Schedule medical exams.

Answer: (B)

The primary purpose of the Dosimetry Program is to quantify and record the radiation doses that workers receive in the workplace, ensuring those doses stay within regulatory limits and supporting dose-reduction efforts. It covers both external exposure, measured with personal dosimeters worn on the body, and internal exposure, estimated through bioassay or other monitoring methods when radioactive materials are inhaled or ingested. This dose history helps identify high‑exposure tasks and guides ALARA practices to minimize risk. The program is focused on occupational exposures for workers and does not track medical exposures to patients or exposures from natural background; those are handled separately or outside the occupational dosimetry framework.
