What is the purpose of a dosimeter?

The primary purpose of a dosimeter is to measure the amount of radiation exposure that a person receives over a specified period. This device is essential in environments where individuals may be exposed to ionizing radiation, such as in medical settings, nuclear power plants, or research laboratories. Dosimeters provide critical data that helps ensure that radiation exposure is kept within safe limits as recommended by health and safety regulations. By accurately tracking exposure levels, dosimeters help in assessing the potential health risks associated with radiation exposure, enabling timely interventions and appropriate safety measures.

The other options focus on different functions that are not the primary use of a dosimeter. For instance, storing radioactive material pertains to containment rather than measurement. Providing protective equipment relates to physical barriers that shield against radiation but does not quantify exposure. Analyzing radiation type involves identifying the specific kind of radiation present, which is a separate function from measuring the dose received by individuals.
