What is the function of a dosimeter badge?

A dosimeter badge is specifically designed to monitor an individual's exposure to ionizing radiation over time. Its primary function is to absorb radiation and record the dose of exposure that a person receives during a specified period. When analyzed, typically at the end of this period, the dosimeter badge provides a cumulative measure of the total radiation dose that the wearer has been exposed to. This information is essential for ensuring that individuals working in environments where radiation is present, such as medical facilities or nuclear sites, stay within safe exposure limits to protect their health.

The design of a dosimeter badge allows it to be worn conveniently, often clipped to clothing, so that the person can go about their normal duties while the badge continuously records exposure without needing to actively check readings at all times. This aspect differentiates it from devices that provide immediate readings or alerts, which serve different functions.
