An aerial radiological survey was conducted over the Braidwood Generating Station, Braidwood, Illinois, during the period 5 August through 16 August 1988. The purpose of the 259-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 (AGL) was constructed from the gamma data and overlaid on an aerial photograph and map of the area. Terrestrial-only exposure rates varied from 0 to 8 microroentgens per hour ({mu}R/h). The highest exposure rates were recorded over strip-mined areas. Lower-than-average exposures rates were measured over bodies of water and large paved areas. No areas of enhanced exposure rates due to man-made radionuclides were observed. 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. 9 refs., 5 figs., 1 tab.
