Any element lying beyond uranium in the periodic table, i.e. any element of atomic number greater than 92. Except for the plutonium isotopes Pu-244 (half-life about 80 million years) and Pu-239 (continuous reformation in rock containing uranium by neutron capture in U-238 by neutrons from the sponta...

Chemical element with an atomic number of 93 or more – that is, with a greater number of protons in the nucleus than has uranium. All transuranic elements are radioactive. Neptunium and plutonium are found in nature; the others are synthesized in nuclear reactions. Research in transuranics is pursued mainly at the Lawrence radiation labora...
