G. PERSONNEL DOSIMETRY. 1, The primary dosimetry device will be the film badge, and the Army Photodosimetry Service shall be employed. The film badge contains one or more photographic emulsions and is designed to differentiate between beta particles, gamma rays, 2. and x-rays. <A film badge will be worn by all personnel upon entering a controlled area. It will be worn on the front surface below the should- ers, above the hips, and on the outside of clothing, except where con- tamination of the badge could occur, or in difficult working conditions where the film badge might be lost or damaged. In such cases, the film badge wiil be worn under protective clothing. 3. The film badge wearer will be responsible for his badge and the contained film and will take care to avoid its exposure to excessive heat, humidity or moisture. 4. <A self{-reading pocket dosimeter will be worn, in addition to the film badge, at all times when an individual is in a radiation area; i.e., in any area in which there exists radiation at such levels that a major portion of the body could receive in any one hour a dose equivalent in excess of 2 mrem or in any five consecutive days a dose equivalent in excess of 100 mrems. Radiation areas will be identified during the initial radiological reconnisance of each island. Exposure accumulated by the pocket dosimeters will be documented, H. PROTECTIVE CLOTHING. 1. Plutonium is the only radiological threat of Cleanup which requires a protective-clothing response. As previously noted, Pu in the an P ha r «£8 5 Ff r & fe & r & b E mr 1&
