Surface Radioactivity at the Plowshare Gas-Stimulation Test Sites: Gasbuggy,Rulison, Rio Blanco

摘要

A surface soil characterization was conducted at three former underground nucleartest sites: Gasbuggy, New Mexico; Rulison, Colorado; and Rio Blanco, Colorado. The abundances of man-made and naturally occurring radionuclides were determined with their contributions to total exposure rate. CS-137 was the only man-made radionuclide detected in the study and was highest at undisturbed locations with little forest litter cover. The amounts observed are consisted with radiocesium fallout concentration observed in other parts of the United States.
