Final answer:
Radiation exposure badges are referred to as dosimeters and are used to record personal radiation exposure, distinguishing them from Geiger counters which measure radiation levels in an area.
Step-by-step explanation:
Radiation exposure badges are used to monitor the amount of ionizing radiation that a person is exposed to, and these badges are commonly referred to as dosimeters. Unlike Geiger counters, which are devices used to detect and measure radiation in an area, dosimeters are designed to be worn and record the radiation exposure over a period of time to ensure safety standards are met and to minimize health risks. Other ways to protect against radiation exposure include using lead aprons for shielding and ensuring minimal time spent near sources of radiation.
