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.

The Health and Environmental Impact of Uranium Mining

However, the process of obtaining Uranium through mining and processing ore also poses serious risks to people and the environment. To complicate these issues further, historically in the United States and around the globe the negative impacts of Uranium mining have fallen disproportionately on low income and minority communities.

NRC: Uranium Enrichment

The gaseous diffusion process uses molecular diffusion to separate a gas from a two-gas mixture. The isotopic separation is accomplished by diffusing uranium [which has been combined with fluorine to form uranium hexafluoride (UF 6) gas] through a porous membrane (barrier), and using the different molecular velocities of the two isotopes to achieve separation.
