transuranic elements (transuranium elements) Elements with atomic numbers higher than that of uranium (92), the best known of which are members of the actinide series (atomic numbers 89 to 103). All transuranic elements are radioactive. Only neptunium and plutonium occur naturally (in minute amounts) but all can be synthesized. The only commercially important transuranic element is plutonium, which is used in nuclear weapons and as a fuel for nuclear reactors.
