Medium energy proton induced fission in uranium-238 and bismuth-209
… proton induced reactions, including fission, in 2380 and 209Bi have been studied. The inelastic interactions of protons with heavy nuclei have been described by a model in which the reaction proceeds in two steps. The first step is the fast cascade where a series of individual particle-particle …

Assessing the bioavailability of the radionuclides technetium-99, selenium-79 and uranium-238 in contaminated soils using the diffusive gradients in thin-films (DGT) technique
The increasing global inventory of 99Tc, 79Se and 238U as components of nuclear waste, coupled with the legacy of contaminated sites, means that increasing attention has been centred on understanding the environmental behaviour of these radionuclides. Over the last 15 years, the technique of …

Use of Chemical and Isotopic Signatures to Distinguish Between Uranium Mill-Related and Naturally Occurring Groundwater Constituents at the Bluewater Disposal Site
Uranium mining and milling in the Grants Mining District (GMD) in northwestern New Mexico resulted in environmental impacts on the areas soil, stream sediments, surface water and groundwater. The Bluewater mill, a predominant mill within the GMD, disposed of tailings in unlined tailings piles …

A variational approach for the calculation of resonance escape probabilities in slab lattices
… The method is set up for a pure non-scattering uranium-238 absorber and a non-absorbing water moderator region. The reaction rate in the fuel region contains two contributions, the first term appears as an integral expression, which can be integrated numerically, the second term can be …

Towards establishing a fit-for-purpose regulatory framework for radiation protection in Western Australia's mining industry: Evaluating mine worker exposures to naturally occurring radionuclides
… of WA is replete with mineralisation that hosts uranium and “critical minerals” required for the global renewable energy sector. The state’s first uranium mine is under development, and high levels of activity are occurring in the state’s nascent critical minerals sector, with 168 WA-based …
