Uranium - Wikipedia

Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years.

Uranium (U) source, speciation, uptake, toxicity and ...

Uranium, being the heaviest naturally-occurring element, is widely dispersed in the Earth’s crust, rocks and soils at a level of approximately 1–4 ppm by weight (Gavrilescu et al., 2009).Yet, the average U concentration in plants, animals, and ocean water is approximately 10 −7 g/g because of the low solubility of U(VI) compounds in water (Szabó et al., 2009).

Mining industry of Russia - Wikipedia

Annual uranium production was about 3,400 t, of which more than 90% was produced by Priargunsky. Uranium-bearing ores and solutions were processed to generate uranium concentrates, which were shipped for further reprocessing at the JSC Chepetsky Mechanical Plant. The country's annual natural uranium consumption amounted to approximately 9,000 t.
