A large proportion of the epidemiological studies performed in the United States, exploring adverse health effects from potential off-site radionuclide releases from uranium mining and processing facilities, have lacked the ability to evaluate causal relationships (e.g., to test study hypotheses) because of their ecological study design.
The presence of underlying uranium deposits may contaminate the upper soil of a region. We have carried out a detailed investigation of radionuclides (Ra, Th, and K) present in the soil around the reported uranium deposit site in the Sikar district of Rajasthan, India. Measurements are carried out using the state-of-the-art gamma-ray …

Wyoming is the largest producer of uranium in the United States. An increase in exploration and extraction comes with renewed interest in nuclear power. Associated is a need to be prepared for handling radionuclide- contaminated soils from leaks and surface spills during in-situ recovery (ISR) of uranium. Uranium mining is …
radionuclides in the studied marble samples is presented in Fig. 5. Table 2 shows the average radionuclide concentrations of 40K, 238U & 232Th in the mining areas. 40K had the highest average radionuclide value of 185.04+37.87 Bq/Kg, 232Th had the lowest average radionuclide value in the areas with a value of 17.76+6.50 Bq/Kg.
A few years after a private company, Morlap Mining and Processing Limited formerly operating under the license of Nigerian Marble Mining Company in Igbeti City, Oyo State, went moribund, another quarry has emerged but with untold hardship for the people, reports GABRIEL OGUNJOBI "Away! Away!!

The release of radionuclides from nuclear sites and their subsequent mobility in the environment is a subject of intense public concern. Natural sources of radioactivity include U (present in Earth's crust at concentration of 1.8 ppm), Th, Ra isotopes, and radon, while significant quantities of natural and artificial/manmade radionuclides were also released …
Radionuclide contents in raw minerals and soil samples and the associated ... dose rate in air at the mining sites ranged from 52.2564.00 nGy h-1. with mean of 57.32- ±4.44 nGy h-1.
Radioactive wastes are generated from nuclear reactions, nuclear power generation, mining activities, and nuclear by-products from medicine and scientific research (Adebiyi et al., 2021; IAEA, 2019; Noor et al., 2020).There is a massive surge in the production capacity of industries around the globe; improvements from 1.2 billion tons to 2.3 billion …
Additionally, the transportation of marble from mining sites to processing plants and markets can contribute to air pollution and greenhouse gas emissions. The extraction and processing of marble also require large amounts of water, which can lead to water scarcity and pollution.
The mining and processing of naturally occurring radioactive materials (NORMs) could result in elevated levels of natural radionuclides in the environment. The …
