Craveson J For To su-vey the gamme raiiation from fallout contaminated ocean sreas using an aircraft horne datactor, Ta me afr sbsorptisa measurements to correlate the aircraft data with the intensities measured at the surface of the sea. INSTRUMNTATION ‘ Three "2V-5 aircraft were equipped .it:, gamme radia‘ion le tectors to record the jose rate arriving through the thin aircraft skin from a water surface below, RESULTS ‘ Flights were accomplished on D, D4 1,042 anid 43 days with one aireraft. The area north of Bikini Atoll Crom 315° to 45° T to aw distance of about 175 miles was covered by the surweys. The contaminai.d area extended north of Sikind aprroximately 125 miles between the bearings 340° and 30° T. The aircraft Program 2 Control Center telemeter system 1143 not operate, The radiation ie‘ector system cperate!d and on D ¢ 1 through D ¢ 3 the intensity measure? at the aircraft was relayed to the Program 2 Plot Center via voice radio. With this data it was possible to cone struct a plot shoving roughly the characteristics of the contaminated BEST AVAILA DLE COPY -i}- ma AGpop,
