Elemental and radionuclide exposures and uptakes by small rodents, invertebrates, and vegetation at active and post-production uranium mines in the Grand Canyon watershed

The fate of inhaled uranium-containing particles upon clearance to gastrointestinal tract

“…The average particle sizes were 9. 32 The SEM images with their respective particle-size distributions are reported in the ESI (Fig. S2 and 3 †).…”

“…On the other hand, Cleveland et al suggested that the gut microbiota may take up uranium and act as a barrier between the body and the uranium in the stomach, thereby reducing the overall impact of uranium on tissue cells. 32 The contrasting conclusions within the scientific literature call for further studies on the topic.…”

Geochemical Distribution and Environmental Risks of Radionuclides in Soils and Sediments Runoff of a Uranium Mining Area in South China

“…Activities associated with ore mining and processing can contribute to elevated levels of naturally occurring radioactive materials and heavy metals in soils and sediments [9][10][11][12][13]. Specifically, uranium mining activities involve minerals from uranium deposits that are rich in 238 U and 232 Th decay series nuclides, as well as 40 K [14,15]. During uranium mining and processing, these natural radionuclides can be released from ore minerals [16], leading to media contamination, as well as food and water contamination due to various pollutants originating from mining operations [17,18].…”
