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 ...
Production of nuclear power relies on the nuclear fuel cycle, which includes uranium mining and milling. Uranium workers are routinely exposed to low levels of radon decay products and gamma radiation. Risks of leukemia from acute and high doses of gamma radiation are well-known, but there is debate about risks from lower doses.
Large-scale uranium mining operations throughout the world have had a significant impact on indigenous peoples and their ways of life, raising questions concerning economic development of "remote regions" in relation to the impact on traditions life styles of these cultures, and resulting health and environmental hazards.

The primary environmental effects of nuclear power come from uranium mining, radioactive effluent emissions, and waste heat. Nuclear industry, including all past nuclear weapon testing and nuclear accidents, contributes less than 1% of the overall background radiation globally.
2021 uranium mining by nation [1] Schematic diagram of stages from uranium mining to energy production. Uranium mining is the process of extraction of uranium ore from the ground. Over 50,000 tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% ...
Uranium acid mine drainage refers to acidic water released from a uranium mining site using processes like underground mining and in-situ leaching. [1] Underground, the ores are not as reactive due to isolation from atmospheric oxygen and water. When uranium ores are mined, the ores are crushed into a powdery substance, thus increasing surface ...
The presence of radioactive waste in the environment may cause long-term effects due to the activity and half-life of the radionuclides, leading their impact to grow with time. [2] These particles exist in various oxidation states and are found as oxides , coprecipitates , or as organic or inorganic complexes, according to their origin and ways ...
The uranium is legally owned by the Australian Government, and is sold internationally, having a large effect on the Australian economy. The mining has been controversial, due to the widespread publicity regarding the potential danger of nuclear power and uranium mining, as well as because of objections by some Indigenous groups. [1]
