What is the function of personal dosimetry devices specifically?

The primary function of personal dosimetry devices is to quantify radiation exposure received by individuals. These devices, which can be in the form of badges, wrist monitors, or dosimeters, are worn by workers in environments where exposure to ionizing radiation is a possibility. They provide vital information on the amount of radiation received over time, helping ensure that exposure stays within safety limits set by regulatory bodies.

By measuring and recording the radiation dose, these devices serve as a crucial component of radiation safety programs. They allow for monitoring of individual exposure levels, which can help prevent exceeding allowable thresholds and enable prompt corrective actions if necessary. This personal monitoring helps to ensure the safety and health of workers in various sectors, such as healthcare, nuclear power, and research facilities involving radioactive materials.
