Beyond naturally occurring uranium, mining, phosphates in agriculture, weapons manufacturing, and nuclear power are anthropogenic sources of uranium in the environment. [ 1 ] In the natural environment, radioactivity of uranium is generally low, [ 1 ] but uranium is a toxic metal that can disrupt normal functioning of the kidney, brain, liver ...
The techniques of bioremediation of environmental areas as soil, water and sediments contaminated by radionuclides are diverse and currently being set up as an ecological and economic alternative to traditional procedures. Physico-chemical conventional strategies are based on the extraction of waste by excavating and drilling, with a subsequent ...
AGM2015: A worldwide v̄ e flux map combining geoneutrinos from natural Uranium-238 and Thorium-232 decay in the Earth's crust and mantle as well as manmade reactor-v̄ e emitted by power reactors worldwide. Environmental radioactivity is part of the overall background radiation and is produced by radioactive materials in the human environment.
Time and again, a mining company promised to clean up uranium waste in New Mexico. Now it wants to buy out residents and avoid full cleanup. Their town was polluted with radioactive waste.
The Uranium Mill Tailings Remedial Action (UMTRA) Project was created by the United States Department of Energy (DOE) to monitor the cleanup of uranium mill tailings, a by-product of the uranium concentration process that poses risks to the public health and environment. The Uranium Mill Tailings Radiation Control Act passed by Congress in 1978 ...
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
Uranium tailings or uranium tails are a radioactive waste byproduct of conventional uranium mining and uranium enrichment. They contain the radioactive decay products from the uranium decay chains, mainly the U-238 chain, and heavy metals. Long-term storage or disposal of tailings may pose a danger for public health and safety.
The 1982 Bukit Merah radioactive pollution is a radioactive waste pollution incident in Bukit Merah of Kinta District in Central Perak, Malaysia.The outcome of the pollution case took several years to complete with no acknowledgement of responsibilities from companies involved despite the closure of factory in 1994 that become the source of pollution.
