Project SCHOONER. Far-Out Fallout Collection Program,
Abstract
The Far-Out Fallout Collection Program was an experimental program to collect and to anlyze samples of longrange fallout from Plowshare nuclear cratering events. Samples of fallout from Schooner, a 31-kt cratering experiment, were collected at downwind distances ranging from 65 to 500 km from the detonation site. The field operations required to obtain the fallout samples and the radiochemsitry techniques used to analyze the samples are described. Measured values of the gamma exposure rate resulting from fallout at downwind locations in eastern Nevada and western Utah are reported. The maximum recorded exposure rate 65 km from the detonation site was 130 mR/hr. Of the 80 fallout samples collected, 16 were radio-chemically analyzed to determine the species and quantities of radionuclides, present. The presence in each anlayzed sample of up to 20 different radionuclides, including 90Sr and 131I, was determined. The radiochemistry results are expressed in terms of deposited radioactivity per unit area (pCi/m squared). (Author)
