In radiation monitoring, what is the primary function of personal dosimeters?

The primary function of personal dosimeters is to measure and record an individual’s radiation exposure. These devices are specifically designed to provide a quantitative assessment of the radiation dose that a person receives during their work in environments where exposure to ionizing radiation is a risk. Personal dosimeters are crucial for ensuring that radiation workers remain within safe exposure limits and for maintaining regulatory compliance.

By routinely monitoring individual exposure, dosimeters help in the implementation of safety protocols and assist in the health surveillance of personnel working in radiation-prone areas. This also aids in identifying trends in exposure levels over time, which is essential for radiation protection programs aimed at minimizing health risks associated with radiation exposure.

Other options, while relevant to various aspects of radiation safety or laboratory maintenance, do not pertain to the primary role of dosimeters. Calculating costs or assessing cleaning efficiency does not directly relate to the core function of monitoring personal exposure to radiation.
