An aerial radiological survey of the Clinton Power Station and surrounding area, Clinton, Illinois, September 1987

Technical Report ·
OSTI ID:6801838
An aerial radiological survey was conducted over the Clinton Power Station, Clinton, Illinois, during the period 22 September--2 October 1987. The purpose of the 256-square-kilometer (100-square-mile) survey was to document the terrestrial gamma environment of the plant and surrounding area. An exposure rate contour map extrapolated to 1 meter above ground level values was constructed from the gamma data and overlaid on an aerial photograph and map of the area. The activity profile of the survey area was extremely uniform, in the range of 10 to 12 microroentgens per hour (..mu..R/h), with the exception of the town of Weldon and the parking lots surrounding the power station. In both cases, the activity was 1 to 2 ..mu..R/h lower than the surrounding terrain due to a smaller concentration of natural radioactive nuclides in the surface material of these areas. The only enhanced exposure rate observed in this survey was associated with the reactor unit. Ground-based exposure rate measurements and soil samples were obtained to support the aerial data. Oblique aerial photographs of the plant were also acquired during the survey. 10 refs., 6 figs., 1 tab.
