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

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."

From Purpose of Survey: "The ARMS-II Parr area survey was one of many that have been flown for the CETO since the nationwide ARMS program was started (1958). Figure 2 shows the location of the areas survey as of Apr. 1, 1964. The purpose of the program is to measure the present environmental levels of gamma radiation in areas around nuclear facilities and planned nuclear activities."
