What is the function of a dosimeter?

The primary function of a dosimeter is to measure an individual's exposure to radiation. These devices are essential for monitoring radiation doses received by workers in various fields, particularly in healthcare, nuclear energy, and research involving radioactive materials. Dosimeters come in various forms, such as film badges, thermoluminescent dosimeters (TLDs), and electronic personal dosimeters, each capable of providing a record of the amount of ionizing radiation a person has been exposed to over time.

By continuously or periodically measuring radiation levels, dosimeters help ensure that individuals do not exceed safe exposure limits established by guidelines and regulations. This monitoring is critical for protecting health and safety, allowing for timely interventions if exposure levels are approaching harmful thresholds.
