Report regarding experiments made to determine the fallout-radiation protection offered by a "single-story stucco and frame house with a heavy shake roof and no basement," (p. 5) which is noted as being popular in the southwestern United States.

Report regarding experiments made to determine the fallout-radiation protection offered by four types of buildings in Los Angeles, California. The first structure was the Laboratory of Nuclear Medicine and Radiation Biology and the University of California at Los Angeles, the second was a fallout shelter, the third was the communications area of the Los Angeles Police Department building, and the fourth was a classroom.

Abstract: "An experimental study was made to determine the effective shielding provided by a modern reinforced-concrete office building (AEC Headquarters building) from nuclear fallout. Pocket ionization chambers were used for measurement of the radiation-field strength. Fallout was simulated with distributed and point-source configurations of Co-60 and Ir-192 sources. Four typical sections were selected for study, and experiments were performed on each. These included an external wing with exposed basement walls and an external wing with a buried basement. Roof studies were made on an internal wing with a full basement and on the east end of wing A, which has a thin-roof construction. The thick-roof construction of 8 in. of concrete and 2 in. of rigid insulation covers all the building except the east end of wing A, which has 4 in. of concrete and 2 in. of insulation."

Report regarding experiments made to determine the fallout-radiation protection offered by several typical homes in the Oak Ridge, Tennessee, area.

Report investigating the protection offered by an earth-covered shelter against fallout radiation. Radiation was simulated by pumping a sealed source of Co60 through tubing.

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

Report discussing the methods, data, and analysis of results for "An experimental study designed to provide a basis for estimating protection against fallout radiation " (p. v) using one- and two-story structures with basements.

Report concerning the protection offered against radioactive fallout offered by two types of structures at the Nevada Test Site. Differences between above ground and underground structures are measured and compared to data taken from actual fallout conditions.

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

Report documenting the survey of the U. S. Army Chemical Corps Schoo, Radiological Instruction Area, Fort Mclellan, Alabama. This survey measures radiation an d gamma-ray flux in an approximately one square mile area.

Report describing an Aerial Radiological Measuring Survey (ARMS) of the Galveston Area between Jan. 27 and Feb. 17, 1962. The survey was part of a nationwide program to measure present environmental levels of gamma radiation. Aerial measurements of ground radioactivity were consistent everywhere with what was expected considering the geology of the area.

Report summarizing "the utilization of the Health Physics Research reactor and a Co60 source during Operation BREN" and offers related meteorological data relating radiation emissions.

Report examining "[t]he effect of ground roughness, or surface irregularities, on the radiation field above ground which had been contaminated with fallout from the explosion in the atmosphere of a nuclear device (Smallboy Event)" (p. v).

From Abstract: "The approach to the problem has been as fundamental as possible with emphasis on quantitative measurements and calculations of the energy, angular, and spatial distributions of weapons radiations in an air-over-ground geometry. Spatial distributions of dose in various shields, including Japanese dwellings, have been measured. Techniques have been developed in Japan for verifying the location of survivors and accurately describing their shielding environments."

From Abstract: "These data are important for personnel protection on a national basis in the event of war and on a local basis in the event of certain types of nuclear accidents. This report discusses the need for such information and suggests methods for obtaining it."

From Introduction: "This report contains a description of the MRMU, detailed operating information, emergency procedures, and health physics operating regulations. Also included are parts lists (Appendix A), an electrical system schematic (Appendix B), a hydraulic system schematic ( Appendix C), and EG &G Drawing No. NE-1054, which shows the shell assembly of the multiple-source pig (Appendix D)."

From Introduction: "The purpose of this report is to describe, step by step, the theoretical studies that have resulted in a mathematical model capable of predicting the motion of objects utilizing selected basic blast parameters."

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."

From Introduction: "The ARMS-II Norfolk - Peninsula area survey was one many that have been flown for the CETO since the nationwide ARMS program was started (1958). Figure 2 shows the location of the areas that have been completed to date. The purpose of the program is to measure the present environmental levels of gamma radiation in areas around nuclear facilities and planned nuclear activities."

From Introduction: "The primary purpose of this report is to describe the analytical procedures involved in the design of a circular slide rule and to discuss its usage and limitations in the evaluation of the effects of nuclear weapons."

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

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."

From Abstract: "The data are presented as aeroradioactivity units or areas with similar gamma radiation counting rates at 500 ft., at two map scales: (1) generalized at about 1: 1,000,000 and (2) detailed at 1:250,000. The maximum aeroradioactivity in almost all the area was less than 400 counts/sec. Aerial measurements of ground radioactivity in the ARMS-II Orlando area were consistent with what was expected, considering the geology of the area."
