use of radioactivity in mining

Naturally occurring radioactive material (NORM) is a term describing materials containing radionuclides that exist in the natural environment. In mining, these might be minerals associated with: uranium ores Uranium ore is mined for the ability to eventually produce energy in nuclear reactors. mineral sands

coltan - wikipedia

Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum …

radiations uses for mining

We use radiation for diagnosis (as in x-rays) and for therapy (as in cancer treatment), but the benefits must be carefully weighed against the costs.These spas were opened in the 1950s at abandoned mining sites in Montana where radon seeps out in unusual amounts

mining industry and sustainable development: time for

Jun 09, 2017 · All these artisanal and agricultural activities created pathways for the transfer of radioactive contaminants and radiation exposure of population, requiring measures to reduce exposure to radioactivity. Mining outside Africa, for example, in Indonesia, China, and Peru, has also developed in situations of elevated risk to humans and the

boom in mining rare earths poses mounting toxic risks

Jan 28, 2013 · The mining of rare earth metals, used in everything from smart phones to wind turbines, has long been dominated by China. But as mining of these key elements spreads to countries like Malaysia and Brazil, scientists warn of the dangers of the toxic and radioactive waste generated by the mines and processing plants

radioactive waste from uranium mining and milling

If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years. It is now primarily used as fuel for nuclear reactors that make electricity

(pdf) radiation technology applications in mining and

Radiotracers and nucleonic gauges are increasingly being applied by the mining, metallurgy and mineral processing industries for the exploration and efficient extraction of natural resources. Such industries exist in most countries and are often

mining uranium: how safe is it and why do it? myths and

Nov 04, 2020 · The uranium from the mine is far from being nuclear fuel. It is an ore with low background radioactivity. In order to use uranium at a nuclear power plant, it must be enriched. The concentration of uranium-235 must be increased from natural to that required for running a nuclear reactor

natural radioactivity assessment of a phosphate fertilizer

Jan 01, 2014 · Their radioactivity leading to health problems from radiation at the level of the industrial processes which involves mining and transportation of phosphate ores and production of fertilizers. At the usage level, when fertilizers dispersed into the geo and biospheres, have a potential to transfer to living beings

radioactivity and radiological hazards from a kaolin

Apr 16, 2018 · In this article, results of in situ measurements of radioactivity concentrations of 40 K, 232 Th, and 238 U as well as gamma doses and radiological hazards from kaolin mining field were presented and evaluated. Eleven stations were randomly occupied in order to cover the upper axis of a kaolin mining field in Ifonyintedo

Apr 07, 2021 · TENORM: Fertilizer and Fertilizer Production Wastes. The most important use of phosphate rock is in the production of phosphate fertilizers. Due to its chemical properties, phosphate rock may contain significant quantities of naturally occurring radioactive materials (NORM): Their decay products decay products The atoms formed and the energy

big winds dirty little secret: toxic lakes and

Oct 23, 2013 · On the other hand, China has cut mining permits and imposed export quotas, but is only now beginning to draft rules to prevent illegal mining and reduce pollution. America may not have a perfect solution to nuclear storage, but it sure beats disposing of radioactive material in toxic lakes like near Baotou, China

uranium: its uses and hazards - institute for energy and

Uranium is the principal fuel for nuclear reactors and the main raw material for nuclear weapons. Natural uranium consists of three isotopes: uranium-238, uranium-235, and uranium-234. Uranium isotopes are radioactive. The nuclei of radioactive elements are unstable, meaning they are transformed into other elements, typically by emitting
