What is the primary purpose of personnel body dosimeters?

The primary purpose of personnel body dosimeters is to measure the amount of external radiation exposure that individuals may receive while working in environments where radiation is present. These dosimeters provide essential information about radiation levels to help ensure safety and compliance with regulatory limits. They are worn on the body, often on the torso, where they can accurately capture the radiation dose received by the individual during their work activities.

By monitoring external radiation exposure, dosimeters help to identify any potential overexposure, allowing for timely corrective actions to protect the health and safety of personnel. This continuous monitoring is crucial in fields such as medical imaging, nuclear energy, and research involving radioactive substances, where understanding radiation exposure is vital for maintaining safe working conditions.
