Estimation of Distribution Coefficient of Uranium and its correlation with soil parameters around Turamdih Uranium Tailings Pond
Predicting the transfer of radionuclides in the environment for normal release, accidental, disposal or remediation scenarios, in order to assess exposure, requires the availability of important generic parameter values. One of the key parameters in environmental assessment, is the solid liquid distribution coefficient, K d , which is used to predict radionuclide–soil interaction and subsequent...
متن کاملDiversity and characterization of sulfate-reducing bacteria in groundwater at a uranium mill tailings site.
Microbially mediated reduction and immobilization of U(VI) to U(IV) plays a role in both natural attenuation and accelerated bioremediation of uranium-contaminated sites. To realize bioremediation potential and accurately predict natural attenuation, it is important to first understand the microbial diversity of such sites. In this paper, the distribution of sulfate-reducing bacteria (SRB) in c...
متن کاملMineralogical controls on aluminum and magnesium in uranium mill tailings: Key Lake, Saskatchewan, Canada.
The mineralogy and evolution of Al and Mg in U mill tailings are poorly understood. Elemental analyses (ICP-MS) of both solid and aqueous phases show that precipitation of large masses of secondary Al and Mg mineral phases occurs throughout the raffinate neutralization process (pH 1-11) at the Key Lake U mill, Saskatchewan, Canada. Data from a suite of analytical methods (ICP-MS, EMPA, laborato...
متن کاملRadiation Dosimetry on Revegetated Uranium Mill Tailings in Western South Dakota
Measurement of gamma radiation using thermoluminescent dosimeters on three uranium mill tailings areas and a control area showed exposure rates below ground depended on the amount and type of soil covering. Covering tailings with 30 cm of shale and 60 cm of topsoil reduced gamma radiation exposure belowground to rates similar to the control area. Soil covering of 30 cm was adequate to reduce ga...
متن کاملSustainable Covers for Uranium Mill Tailings, Usa: Alternative Design, Performance, and Renovation
The U.S. Department of Energy Office of Legacy Management is investigating alternatives to conventional cover designs for uranium mill tailings. A cover constructed in 2000 near Monticello, Utah, USA, was a redundant design with a conventional low-conductivity composite cover overlain with an alternative cover designed to mimic the natural soil water balance as measured in nearby undisturbed na...
