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 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 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 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 concerning "[a]n airborne gamma-radiation survey of Connecticut, Rhode Island, and parts of New York, Massachusetts, New Hampshire, and Vermont" (p. 5) made between 1958 and 1960 that indicated that a broad range of radioactivity exists in those areas depending on the type of bedrock. Correlations are drawn between this radioactivity and the geology of the region.

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