transuranic element

any of the elements with atomic numbers above that of uranium (whose atomic number is 92). All are radioactive and have very short half-lives. None, except for neptunium and plutonium in very small amounts, occurs naturally. They are produced artificially in nuclear reactors and particle accelerators. Also called transuranium element.
