What term is used for the measurement system that tracks radiation exposure in workers?

• A. Dosimetry
• B. Dosimeters
• C. Geiger counters
• D. Exposure meters

Answer: (A)

Dosimetry is the system used to measure and track the radiation dose a worker receives over time. It covers the methods and records used to quantify dose, monitor exposure history, and ensure safety limits are met, typically through personal dosimeters worn by workers that accumulate dose and are read periodically. The devices themselves—the dosimeters—record the dose, but dosimetry refers to the whole program of measurement and record-keeping. Tools like Geiger counters measure real-time radiation events and don’t provide a record of cumulative occupational dose, and exposure meters usually indicate current exposure rate rather than total dose. So the term for the measurement system is dosimetry.
