The Aerial Measuring Systems (AMS) * was used to survey the area surrounding the Dresden Nuclear Power Plant during September 1972. The survey measured terrestrial gamma-ray exposure rate and spectral data. A high-sensitivity detection system collected gamma-ray spectral and gross count data. The data were then processed to construct a map of a 625 square mile area showing the spatial distribution of gamma-ray exposure rates 1 m above the ground. Exposure rates and isotopes identified are consistent with that related to normal terrestrial background radiation. The Dresden area was surveyed in 1968 and 1970. Comparison of the 1968 and 1970 surveys shows no measurable change in the terrestrial gamma exposure rates. Comparison of the 1968 ad 1970 surveys indicates a slight decrease in the average terrestrial exposure rate. 9 refs., 9 figs., 4 tabs.
