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!!
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.
Ajiwei mining site in Shiroro Local Government area in Niger State, North Central Nigeria. A framework for the protection of the environment against the hazards of radiations from the minerals mining requires a logical methodology for proper assessment of the dose rate arising from the naturally occurring radionuclide.

Five major mining sites in Benue state were identified. These are mining sites from which the raw minerals, Limestone, Kaolin, Clay and Baryte are obtained in the state. At each site two (2) samples of the type of mineral mined were collected. Also about 10 soil samples were collected at different locations around the mining area.

The mining of minerals is the basis of a large part of the world economy, and provides the raw materials for most of the infrastructures and tools that we use in everyday life. ... and in minerals processing activities often implemented by the mine sites. In addition, radionuclide and radiation exposure obviously occur in uranium mines ...
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 consequences of climate change (CC) have already led to global social, economic, and environmental impacts 1.The emerging interaction between CC and the sources and cycling of contaminants ...
Studies should be carried on the active concentration of radionuclide in water, food crops and livestock around the mining sites to provide a comprehensive information on the number of radionuclides that gets into the food chain, and human exposure at mining …
The tin mining activities in the suburbs of Jos, Plateau State, Nigeria, have resulted in technical enhancement of the natural background radiation as well as higher activity concentrations of primordial radionuclides in the topsoil of mining sites and their environs. Several studies have considered the radiological human health risks of the …

These results indicate that sand, marble and limestone samples have normal levels of natural background radiation. On the contrary, granite samples have higher levels of natural background radiation. The absorbed dose rate was found to be lower than the worldwide average for bigger grain sizes in sand, marble, and limestone samples.
