Popis: The six crystal, NaI scintillation gamma-ray detector used by the U. S. Geological Survey for the past several years in making radiation surveys through the United States and Alaska is described. It is shown that the variation of radiation with height above ground in the neighborhood of 500 ft can be adequately expressed by use of a buildup factor which varies proportionately with height. Measurements of point and broad sources are shown to compare well with theory. (auth)
