Film Badge

The Film Badge is a type of Passive Dosimeter. It consists of a photographic emulsion film, which responds to Ionising Radiation by changing optical density, in a light tight wrapping (contained in a holder). The holder, which also contains various filters (for measuring tissue equivalent quantities), is usually worn on the trunk of the body.
