Soil samples and ion chamber measurements were obtained at four locations to support the aerial data. The highest area of increased activity was directly attributed to the main units of the plant and indicated the presence of /sup 60/Co and /sup 58/Co. mu.Rh in the immediate vicinity of LongviewKelso, Washington. The exposure rates varied from 8 to 10 microroentgens per hour (.mu.Rh) more » in the southern and northernmost regions of the survey area with somewhat lesser rates of 6.5 to 8.0. The C-SPAN School Bus visited Waxahachie, Texas, the construction site of the Superconducting Super Collider. A contour map of the terrestrial gamma exposure rate was prepared and overlaid on a USGS topographic map of the area. Count rates were converted to exposure rates at 1 meter above the ground. The survey was conducted at a nominal altitude of 46 meters (150 feet) with line spacings of 76 meters (250 feet).

Since 1989 the Superconducting Super Collider Laboratory, in Waxahachie, Texas, has been designing and is now building the most powerful subatomic particle.
