] | A | Measurement of exposure to radioactivity is important for anyone who deals with radioactive materials on a regular basis. Perhaps the simplest device is a personal dosimeter – a film badge that will fog up when exposed to radiation. The amount of fogging is proportional to the amount of radiation present. These devices... |
