What device is used to measure occupational radiation exposure?

The dosimeter is specifically designed to measure the amount of radiation exposure that an individual receives over a certain period, making it the standard device for monitoring occupational radiation exposure. It records doses of ionizing radiation while being worn by individuals in environments where they are potentially exposed to radiation, such as nuclear power plants, hospitals, or research facilities.

Dosimeters can come in various forms, including film badges, thermoluminescent devices, and electronic personal dosimeters, each providing valuable data about the cumulative exposure to radiation. This information is crucial for ensuring that exposure levels remain within safe limits and for complying with regulatory requirements regarding radiation safety and health.

In contrast, a radiation meter generally refers to devices that measure radiation levels in a specific environment rather than individual exposure; a Geiger counter is one type of radiation meter primarily used for detecting and measuring ionizing radiation in the surroundings rather than personal exposure; and radiographic film is used in imaging processes and does not measure exposure in real time, making it unsuitable for tracking occupational exposure.
