Summary:Natural decay series radionuclides were studied in the environment around a uranium mineralization in southwestern Scotland. A general geochemical description of the site is developed in which the radionuclide source term is characterized and the release rate of uranium from the vein is estimated. Dispersion of uranium for distances of up to 50m is observed in post glacial silts while the virtual insolubility and immobility of thorium under the same ambient conditions is confirmed. Three distinct retardation processes affecting uranium during groundwater transport are identified and characterized. Similarly two retardation mechanisms are identified for radium.—Modified report abstract.
