What is the purpose of the dosimetry program in a radiology department?

• A. To schedule patient appointments.
• B. To monitor and manage radiation exposure to personnel and optimize protection.
• C. To reduce imaging costs.
• D. To train physicians in image interpretation.

Answer: (B)

The main idea is to protect people by measuring and controlling radiation exposure. Personal dosimeters are worn by staff to track how much radiation they receive, and the results are reviewed by the radiation safety office to ensure doses stay within regulatory limits and, as much as possible, are kept as low as reasonably achievable. When readings indicate higher exposure or risky trends, the program guides corrective actions such as improving shielding, changing procedures to reduce time near sources, increasing distance, using appropriate protective equipment, or adjusting staffing. It also provides the documentation needed for compliance with state and federal requirements and for annual safety reviews. This focus on monitoring and protecting staff distinguishes it from activities like scheduling patient appointments, cutting imaging costs, or training physicians in image interpretation, which fall into other areas of department operations.
