Question

People who work around radioactivity wear film badges to monitor the amount of radiation that reaches their bodies. Each badge consists of a small piece of photographic film enclosed in a lightproof wrapper. What kind of radiation do these devices monitor, and how can they determine the amount of radiation people receive?

Answer 1

Explained

Step-by-step explanation:

People who work around radioactivity wear film badges to monitor the amount of radiation that reaches their bodies to prevent themselves from the harmful gamma rays. These film badges monitor gamma rays. Gamma rays are a form of electromagnetic radiation. As a result the greater of the exposure the darker the film will be once produced. So, by measuring the darkness of these films one can easily determine the amount of radiation people receive.
