What is the purpose of TLD badges?

The purpose of TLD (Thermoluminescent Dosimeter) badges is to measure radiation exposure. These badges are designed to monitor an individual's radiation dose over time. When exposed to ionizing radiation, the material inside the TLD badge stores energy, which can later be released as light when heated. The amount of light emitted is proportional to the radiation dose received, allowing for an accurate assessment of exposure levels.

TLD badges are crucial for ensuring safety in environments where radiation is present, such as hospitals, research labs, and nuclear facilities. By quantifying the radiation exposure, they help in the implementation of safety protocols to limit and manage radiation risks. Thus, their primary function is to serve as a reliable tool for monitoring exposure rather than providing shielding, ventilation, or detecting contamination directly.
