The Aerial Radiological Measuring System (ARMS)* was used to survey the area surrounding the Oconee Nuclear Station during May 1973. A high-sensitivity detection system collected gamma-ray spectral and gross count data. The data were then processed to construct a map of a 1893 km2 area showing the spatial distribution of gamma-ray exposure rates one meter above the ground. The aerial data were supported by ground based measurements. Exposure rates and isotopes identified are consistent with that related to normal terrestrial background radiation.
