What is the primary purpose of wearing a TLD or film badge?

The primary purpose of wearing a TLD (Thermoluminescent Dosimeter) or film badge is to measure radiation exposure. These devices are specifically designed to record the amount of radiation that a person is exposed to over time. When radiation interacts with the materials in the TLD or film badge, it causes changes that can later be measured, providing an accurate assessment of the individual's exposure levels.

This is crucial for ensuring safety in environments where radiation is present, as it helps workers and employers monitor exposure and comply with occupational safety regulations. Regular monitoring allows for effective management of radiation exposure and helps mitigate health risks associated with excessive exposure to radiation.
