Release and Movement of Radionuclides in Soils Contaminated with Fallout Materials from an Underground Thermonuclear Detonation

Fallout material from an underground thermonuclear detonation was analyzed to determine the presence of several longer lived radionuclides. The following radionuclides were identified: Zr95-Nb95, Ru103, Ru106- Rh106, I131, Cs137-Ba137, Ba140-La140, Ce141, Ce144-Pr144, Sc46, Mn54, Y88, Rh102, W181, W...

Description
Summary:Fallout material from an underground thermonuclear detonation was analyzed to determine the presence of several longer lived radionuclides. The following radionuclides were identified: Zr95-Nb95, Ru103, Ru106- Rh106, I131, Cs137-Ba137, Ba140-La140, Ce141, Ce144-Pr144, Sc46, Mn54, Y88, Rh102, W181, W185, and W188-Re188. Radiotungsten contributed the major fraction of the total activity. In suspension studies, chelating agents as compared to water, generally increased the amount of soluble radionuclides, but the effect was small. The effect of water and a chelating agent on the movement of radionuclides in soil columns were also studied.
