transuranic elements
Post-uranium atomic substances
Transuranic elements are chemical elements with atomic numbers greater than 92 (uranium)—the heaviest naturally occurring element.
All transuranics are radioactive and artificially produced in nuclear reactors or particle accelerators: plutonium, neptunium, americium.
Transuranic waste from nuclear plants requires special disposal.
Also called transuranic metals or transuranium elements.
