An aerial radiological survey of the Superconducting Super Collider Laboratory and surrounding area, Waxahachie, Texas. Date of survey: July--August 1991

An aerial radiological survey was conducted over the Superconducting Super Collider Laboratory (SSCL) site from July 22 through August 20,1991. Parallel lines were flown at intervals of 305 meters over a 1,036-square-kilometer (400-square-mile) area surrounding Waxahachie, Texas. The 70,000 terrestrial gamma energy spectra obtained were reduced to an exposure rate contour map overlaid on a United States Geological Survey (USGS) map of the area. The mean terrestrial exposure rate measured was 5.4 {mu}R/h at 1 meter above ground level. Comparison to ground-based measurements shows good agreement. No anomalous or man-made isotopes were detected.
