What are dosimeters used for?

Dosimeters are specialized devices used primarily to measure and record an individual's exposure to radiation over time. They are critical in environments where radiation is present, such as in nuclear power plants, medical facilities using radiological equipment, and research laboratories.

The primary function of a dosimeter is to provide a measurable indication of how much radiation an individual has been exposed to, which is essential for ensuring safety and compliance with health regulations. They can take various forms, including badges, electronic devices, or film, depending on the context and required sensitivity.

In contrast, other options refer to different roles that involve radiation but do not align with the primary function of dosimeters. Storing data from experiments, detecting leaks in shielding, and calibrating instruments serve important purposes in radiation safety and monitoring, but they do not pertain to the measurement of individual radiation exposure in the way dosimeters do.
