Photographic film goes darker when it absorbs radiation, just like it does when it absorbs visible light. The more radiation the film absorbs, the darker it is when it is developed. People who work with radiation wear f The way in which these defects may be overcome is illustrated by reference to the film dosimeter developed by the Radiological Protection Service, the functioning of which is described in detail.

film badge Radiation safety A dosimeter worn by radiation workers to monitor radiation exposure; FBs contain a piece of film that is darkened by radiation, and may contain filters which shield parts of the film from certain types of radiation. TLD badges are quite similar to film badges in their appearance and the physics behind how they function, but due to the elements used in their design, they are much more sensitive and can measure much lower doses of radiation. The UD-800 Series TLD Badges use very thin elements of tissue-equivalent Li2B4O8:Cu and ultra-sensitive CaSO4:Tm. 2014-07-08 · Film Badge: Dosimeter Type: Single Packet, Double Emulsion Personal Monitoring Film: Minimum Reportable Dose: 10 mrem (0.10 mSv) Useful Dose Range: 10 mrem - 500 rads (0.10 mSv - 5 Gy) Photon Energy Response: 5 keV - 3 MeV: Beta (MAX) Energy Response: 1.71 MeV - 5 MeV
