Which tool is commonly used for detecting radiation exposure?

A dosimeter is a specialized device used to measure and record the amount of ionizing radiation exposure that an individual receives over time. This tool is essential for professionals working in environments where they might encounter radiation, such as radiographers and nuclear workers. By providing a reliable way to monitor exposure levels, dosimeters help ensure that safety protocols are followed and that exposure remains within regulatory limits to protect workers' health.

Calipers are used for measuring lengths and distances, but they do not have any capability to detect radiation. Spectrometers can analyze the properties of radiation but are not typically used for personal exposure monitoring. Thermometers measure temperature and are unrelated to radiation exposure detection. Therefore, the dosimeter stands out as the appropriate tool for monitoring radiation exposure in the context of industrial radiography and other radiation-related fields.
