What is a dosimeter and when should it be used?

• A. A device that measures a worker's temperature exposure.
• B. A device that measures a worker's radiation dose over time; used for monitoring cumulative exposure.
• C. A device that counts the number of hours worked.
• D. A device that monitors air quality.

Answer: (B)

A dosimeter is a device that records the amount of radiation a person is exposed to over a period of time, allowing you to monitor cumulative dose. In workplaces where ionizing radiation is present—such as medical imaging, radiography, nuclear medicine, or industrial radiography—the dosimeter is worn by workers so readings can be collected and tracked to ensure exposure stays within regulatory limits. Readouts from dosimeters can come in several forms, including film badges, thermoluminescent dosimeters (TLDs), optically stimulated luminescence (OSL) dosimeters, and electronic personal dosimeters, and they’re read at set intervals to assess current and past exposure. This tool is specifically about radiation dose, not temperature, hours worked, or air quality. Temperature monitoring is done with thermometers or heat-stress sensors; counting hours worked is handled by time-tracking devices; monitoring air quality uses air samplers and gas or particulate sensors. Use a dosimeter whenever there is potential exposure to ionizing radiation to help protect workers and comply with safety and regulatory requirements.
