Solution 21Q :
A film-badge dosimeter is a device commonly used to measure and record radiation exposure due to gamma rays, X-rays and beta particles.A film badge provides a simple and an inexpensive way for measuring a person’s cumulative (The total amount of a substance or radiation that a person is exposed to over time) exposure to radiation.
The film badges are collected and processed regularly to monitor exposure. The more exposed the film becomes in a given period of time, the more radioactivity the person has been exposed.
