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."

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.

From Abstract: "The Oak Ridge National Laboratory (ORNL) Health Physics Research Reactor is to be attached to a hoist platform on a 1500-ft tower at the Nevada Test Site (NTS). The project is a continuation of the studies commenced in 1956 for evaluating the radiation doses of persons exposed to nuclear weapons, especially the residents of Hiroshima and Nagaski, Japan. Measurements will be made of the energy, angular, and spatial distributions of the radiation from the reactor."

Report regarding an airborne radioactivity survey that took place in the 10,000 square mile area surrounding the National Reactor Testing Station in Idaho Falls, Idaho. Topics include the types of bedrock noted in the area as well as their levels of radioactivity.

Report regarding an airborne radioactivity survey that took place over a 10,000 square mile area around the Oak Ridge National Laboratory near Knoxville, Tennesse. Topics include the types of bedrock noted in the area as well as their levels of radioactivity.

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 an experimental study to determine how much protection the Medical Research Center at Brookhaven National Laboratory provided against nuclear fallout. Fallout was simulated by pumping a sealed source of Co60 through tubing.

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."

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 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).

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.

Report wherein the distribution of neutron and gamma radiation in Japanese-style single and group houses are studied to evaluated radiation exposure in Hiroshima and Nagasaki.

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

From Introduction: "The elimination of the burn hazard in shelters depends upon a separate, systematic investigation of each suspected agent. The purpose of the present investigation was to evaluate the contribution made by radiant energy and, if such contribution proved to be significant, to suggest means of eliminating this component."
