PROGRAM 2 - NUCLEAR EFFECTS Program Director - LtCol E. A. Martell, USA Project 2,] - GAMMA RADIATION DOSIMETRY Project Officer - Major-R. Dempsey Objective To measure the gamma radiation exposure at various locations following a nuclear detonation. Instrumentation + . Film and chemical dosimeters were placed in ¢ inch wall aluminum cannisters mounted on 2 inch aluminum stakes. The detectors were placed at a height of 3 ft above ground for the land stations. The beach stations were set so that the detectors were 1 ft above maximumhigh tide level. Both detecting systems were calibrated against an 11-Mev betatron. (See Table 2.1-1) , Results wo produce a consistent decay expression for stations 34 thru 41. UL ryt nec COPiED/ Due ananine ag u
