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 airborne gamma-radioactivity survey that took place in the 2,800 square mile area around the Los Angeles region in California. Topics include the types of bedrock noted in the area as well as their levels of radioactivity.

This report follows an aeroradioactivity survey that took place in the San Francisco region, California.

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.

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.

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."

"An Aerial Radiographic Measuring Survey (ARMS) of the Arguello area was made for the Civil Effects Test Operations, Division of Biology and Medicine, U.S. Atomic Energy Commission, by Edgerton, Germeshausen & Grier, Inc.(EG&G), between Apr. 5 and Apr. 29, 1962. The survey was part of a nationwide program to measure the present environmental levels of gamma radiation" (p. 5).

Report regarding an Aerial Radiological Measuring Survey (ARMS) of the Camden-Delaware Valley area that was part of a national program to measure environmental levels of gamma radiation. 6,000 traverse miles were examined around Camden, New Jersey.

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.
