Study on Role of ²³⁴Th in Uranium Series Nuclides Migration

MRS Proceedings, 1990
ABSTRACTThe role of 234Th, a daughter nuclide of 238U having a half life of 24 days, in the migration of uranium series nuclides has been studied to understand the mechanism which gives a higher migration velocity of 238U than that of 234U. We assume that 234Th is adsorbed at two different sites; one, where 234Th is reversibly adsorbed, and the other ...

Physical and chemical features of the Chernobyl nuclides migration processes in the rivers of Belarus

1997
Abstract Data on the radioactive contamination of river systems in southeastern Belarus as a result of the Chernobyl accident are reported for the first time. Results covering several years' work are presented giving levels of a number of radionuclides (Cs-134, Cs-137, Sr-90, Pu-238, Pu-239, Pu-240, Am-241 and “hot” particles) in water, suspended ...

Nuclide Migration Field Experiments in Tuff, G Tunnel, Nevada Test Site

MRS Proceedings, 1981
ABSTRACTA project to begin to address the phenomena of flow and element migration in fractured porous rock has recently been started by the Los Alamos National Laboratory, Sandia National Laboratories, and Argonne National Laboratory. The work has three objectives: 1) to develop the experimental, instrumental, and safety techniques necessary to conduct

Migration of radiocontaminants in a forested wetland on the canadian shield: Nuclide speciation and arboreal uptake

Science of The Total Environment, 1983
Abstract Nuclide speciation and arboreal uptake have been studied in a forested wetland adjacent to a radioactive waste management area at the Chalk River Nuclear Laboratories in Ontario, Canada. A variety of speciation techniques has revealed the presence of anionic species of several radionuclides in the groundwater. In particular, 60 Co exists in
