What is a dosimeter?

• A. A dosimeter that measures and records the amount of radiation to which the wearer is exposed
• B. A device for measuring room dimensions
• C. A device for sampling paint
• D. A device for detecting moisture

Answer: (A)

A dosimeter is a device used to measure and record the amount of ionizing radiation a person is exposed to. It is worn by workers, often as a badge or small electronic unit, and it accumulates the radiation dose over time so safety officers can ensure exposure stays within limits. There are different forms, including film badges, thermoluminescent dosimeters, and electronic personal dosimeters, all serving the same purpose of tracking cumulative dose. In lead inspection work that uses X-ray based tools, a dosimeter helps protect the inspector by monitoring radiation exposure. The other options describe tools for measuring room dimensions, sampling paint, or detecting moisture, none of which relate to monitoring radiation exposure.
