Answer:
film sensitive to radiation that is removed and developed to measure exposure.
a device used for monitoring individual cumulative exposure to ionizing radiation.
Step-by-step explanation:
Film badges are monitoring devices that contain photographic film which measures and record the wearer’s exposure to different ionizing radiation such as X-rays, gamma rays and beta particles. The photographic film within film badges is very sensitive, functions as a detector, and is enclosed in a vapor and light resistance cover which disallows chemical vapors, light or moisture to have an effect on the film. Film badges give a lasting radiation record and it can also differentiate between different energies of photons.
