Abstract:

Underground nuclear explosions produce radioactive contaminants which can be transported with ground water. In order to accurately determine the variation in radioactive contaminant concentration in the hydrologic system in the vicinity of an underground nuclear explosion site, the initial spatial distribution and concentration of radionuclides in the cavityrubble chimney complex must be known. An extensive analytical program was conducted by Teledyne Isotopes, Palo Alto Laboratories, for the U.S. Atomic Energy Commission to determine the spatial distribution of major radioactive contaminants in the one accessible rubble chimney, Rainier. Concentrations of the fission products Cs137, Sr90, Ru106, Ce144, and Sb125 and the activation products Cs134, Co60, Eu152-154, and Fe55 were measured on 5 identifiable rock types melt-glass, contact melt, altered rubble, rubble, country rock, and an inseparable mixture of meltrubble material. No data interpretation is given. Author
