The Division of Biology and Medicine (DBM), Atomic Energy Commission, requested that Edgerton, Germeshausen & Grier, Inc., perform a system analysis of the Aerial Radiological Monitoring Survey (ARMS) program. The objective of the analysis was to determine the feasibility of reducing the volume and the weight of the radiation-detection instrumentation and of making other possible improvements, including navigation and data reduction to yield ground-radiation-contour maps at a reduced operating cost. The present Division of Biology and Medicine--U.S. Geological Survey cooperative ARMS program is reviewed, and a philosophy of an optimum approach covering only the area of DBM interest is developed. The existing aerial radiometric measurement system is unsuitable in the light of present DBM requirements. The electronic design of a revised ARMS system is outlined in detail.
