What is the main purpose of the occupational monitoring program?

• A. To ensure zero exposure
• B. To reduce patient dose
• C. To estimate the amount of radiation received
• D. To replace shielding

Answer: (C)

The main idea is to measure and estimate how much radiation a worker has actually received during their work. Personal dosimeters worn by staff track external exposure over a defined period, and the resulting dose (often expressed in milliSieverts) becomes part of the worker’s dose history. This information is the foundation for verifying compliance with regulatory dose limits, guiding protective actions to keep exposures as low as reasonably achievable (ALARA), and catching any unusual or high exposures so corrections can be made. It’s a measurement and management tool, not a means to guarantee zero exposure or to directly reduce patient dose, and protective measures like shielding and safe work practices operate alongside monitoring to minimize risk.
