An aerial radiological survey was conducted during the period 19 through 31 March 1987 over a 260-square-kilometer (100-square-mile) area surrounding the River Bend Station located near St. Francisville, Louisiana. The survey was conducted at a nominal altitude of 91 meters (300 feet) with line spacings of 152 meters (500 feet). A contour map of the terrestrial gamma exposure rate extrapolated to 1 meter above ground level was prepared and overlaid on an aerial photograph and a set of United States Geological Survey (USGS) topographic maps of the area. The terrestrial exposure rates varied from about 8 to 10 microroentgens per hour (..mu..R/h) at 1 meter above the ground. The levels over the nuclear power reactor were above background. A machine-aided search of the data for man-made sources of radiation indicated the presence of a man-made source of radiation to the west of the River Bend Station. This source proved to be a 70-curie Co-60 source belonging to the Gulf States Utilities coal-fired electric power plant. Spectra of the River Bend reactor did not show the presence of unexpected radioisotopes. Soil samples and pressurized ion chamber measurements were obtained at four locations within the survey boundaries to support the aerial data. 7 refs., 10 figs., 3 tabs.
