What is the definition of a dosimeter?

A dosimeter is specifically designed to measure the dose of radiation exposure that an individual receives over a period of time. This device is crucial for radiation workers as it allows them to monitor their exposure to radiation, ensuring that it remains within safe limits established by regulatory bodies. Dosimeters can be in various forms, such as badges, thermoluminescent devices, or electronic instruments, and provide essential data that helps in maintaining the health and safety of personnel working in environments where radiation is present.

The options that do not correspond to the definition of a dosimeter include those that describe tools measuring physical capabilities, training aids, or equipment meant to protect from radiation. None of these functions involve the direct measurement of radiation exposure, which is the core purpose of a dosimeter.
