What does a Primary Dosimeter provide?

A Primary Dosimeter provides a legal record of radiation exposure. This device is specifically designed to accurately measure the amount of ionizing radiation a worker is exposed to over a defined period. The readings obtained from a Primary Dosimeter are critical not only for ensuring the safety of employees working in radiation environments but also for regulatory compliance.

The data collected through a dosimeter serves as an official record that can be referred to in case of occupational safety investigations or health assessments. This legal aspect is essential, as it helps employers and relevant authorities ensure that exposure levels remain within safety limits set by regulations.

While some of the other options suggest different functions—such as providing temporary records, acting as a warning system, or serving as a manual—they do not accurately describe the specific and formal role of a Primary Dosimeter in the context of radiation exposure monitoring.
