Aerial radiological measuring survey of the area surrounding the La Crosse Boiling Water Reactor, Genoa, Wisconsin, July 1968

The Aerial Radiological Measuring System (ARMS) was used to survey the area surrounding the La Crosse Boiling Water Reactor during July 1968. The survey measured terrestrial gamma radiation. A high-sensitivity detection system collected gamma spectral and gross-count data. The data were then computer processed into a map of a 625 sq. mile area showing isoexposure contours 3 ft above the ground. Exposure rates and isotopes identiiied are consistent with normal background radiation. (auth
