Naturally Occurring Radioactive Materials (NORM) in Produced Water and Oil-Field Equipment— An Issue for the Energy Industry A Introduction Naturally occurring radioactive elements such as uranium, radium, and radon are dissolved in very low concentrations during normal reactions between water and rock or soil. Ground water that

Radioactive isotopes, or radioisotopes, occur naturally in the earth's crust. They are chemical elements that give off radiation. Mineral sands contain small amounts of naturally occurring radioactive material (NORM) which is mainly uranium and thorium and their natural decay products. The radioisotope impurities in what are collectively

Most naturally occurring radioactive material (NORM) contains radionuclides from the so-called long-lived 'primordial' decay chains, resulting from the decay of U-238, U-235, Th-232, and other long-lived radionuclides, such as K-40. All soils and rocks are naturally radioactive, and hence all ores are also radioactive. This is

The radioactive element uranium exists in very small amounts (parts per million) in rocks, soils, and water. The half-life of its most common isotope, 238 U, is approximately 4.5 billion years, making it ideal for radiometric dating of the oldest rocks on Earth. The most common ore of uranium is uraninite, which is mined in a variety of ways including open pit, underground, and leach mining ...

A form of waste associated with mining activities is related to the type of deposit being mined and to the procedure of exploitation and enrichment adopted. The wastes usually contain relatively large amounts of technologically enhanced naturally occurring radioactive materials (TENORM). The TENORM are often stored on the surface.
