For Uranium we have terms and definitions in 5 topics. The topics are Energy, Environment, Environmental Toxins, Explosives and Oceanography.

Uranium (Energy)

A radioactive element, found in ores, of which atoms can be split to create energy.

Uranium (Environment)

A heavy, radioactive metal (atomic number 92) used in the explosion of nuclear weapons (especially one isotope, U-235).

Uranium (Environmental Toxins)

The heaviest element found in nature. Approximately 997 out of every 1000 uranium atoms are uranium-238. The remaining 3 atoms are the fissile uranium-235. The uranium-235 atom splits, or fissions, into lighter elements when its nucleus is struck by a neutron. One of four primary radionuclides in FUSRAP wastes, including radium-226, radon-222 and thorium-230.

Uranium (Explosives)

Uranium (y?-rä´në-?m) (U), radioactive metallic element, discovered in oxide form in Pitchblende by M.H. Klaproth in 1789. A silver-white, hard, dense, malleable, ductile, highly reactive metal in the Actinide series it occurs naturally as a mixture of three Isotopes. Because of a constant decay rate, the age of uranium samples can be estimated (v Dating). The rare uranium-235 isotope is the only naturally occurring fission fuel for Nuclear Energy. Breeder reactors convert the abundant but nonfissionable uranium-238 into fissionable plutonium-239. Uranium-235 and plutonium-239 are also practicable fissionable nuclei for Atomic Bombs. Element; Nuclear Reactor; Periodic Table; Radioactivity.
