Import of Uranium by India

Uranium is a chemical element which is found in nature as uranium-238, uranium-235 and a very small amount of uranium-234. It decays very slowly by emitting an alpha particle but has an exceptionally long half-life (uranium-238  has a half-life of about 4.47 billion years while uranium-235 has a half-life of 704 million years). It makes ..

US Nuclear waste dump plant marks 20 years
