Final answer:
Radiation workers wear film badges to measure their exposure to radiation. The film reacts to radiation, causing it to darken, which helps workers determine their level of exposure. Film badges are a simple and effective way to monitor and control radiation exposure in the workplace.
Step-by-step explanation:
Radiation workers wear a film badge to measure their exposure to radiation. The film in the badge is designed to react to radiation, causing it to darken when exposed. By measuring the level of darkening on the film, workers can determine the amount of radiation they have been exposed to.
The film badge contains various absorbers to determine the penetrating ability of the radiation as well. Different types of radiation will interact differently with the absorbers, allowing workers to identify the type of radiation they have encountered.
Using film badges is a simple and effective way to monitor and control radiation exposure in the workplace. It allows workers to track their exposure levels and take appropriate precautions to ensure their safety.
