Report containing information regarding the airborne radiometric equipment intercalibration exercises undertaken by four government agencies and one private companies.

Report discussing "descriptions of the HPRR and the Co^60 source, their operating procedures, the manner in which they will be used, and possible hazards are included."

Report describing "the design, installation, and performance of the Edgerton, Germeshausen & Grier, Inc., Aerial Radiological Monitoring System used in Phase II of the Aerial Radiological Monitoring Survey (ARMS-II)" (p. 5). Contains descriptions and photographs of its components and descriptions of test runs.

Report of a study that "was conducted to determine the attenuation provided by vertical and horizontal barriers exposed only to skyshine radiation from cobalt-60 and cesium-137 sources. Materials of steel, aluminum, concrete, and wood were used as barriers" (p. 5).

From Abstract: "Certain characteristics of the neutron field from this unshielded reactor were measured. The activation of gold, manganese, sulfur, cadmium-covered gold, and cadmium-covered manganese was determined as a function of distance from the reactor and of depth in the ground. The data show how those parameters, important for calculating neutron-induced activity in the soil, vary as a function of the height of the source and the slant range from the source."

Report containing results of a study that sought to measure the intensification of radiation at various distances from point sources.

Report describing and comparing the effects of atomic explosions on a variety of family shelters. The structures, test conditions, and instrumentation are described.
