The transuranium (or transuranic) elements are the chemical elements with atomic number greater than 92, which is the atomic number of uranium. All of them are radioactively unstable and decay into other elements. Except for neptunium and plutonium, which have been found in trace amounts in nature, none occur naturally on Earth and they are ...
Transuranic waste (TRU) is stated by U.S. regulations, and independent of state or origin, to be waste which has been contaminated with alpha emitting transuranic radionuclides possessing half-lives greater than 20 years and in concentrations greater than 100 nCi/g (3.7 MBq/kg).
Transuranium elements – Elements with atomic number greater than 92. Valve metal - a metal which, in an electrolytic cell, passes current in only one direction.

Edwin Mattison McMillan (September 18, 1907 – September 7, 1991) was an American physicist credited with being the first to produce a transuranium element, neptunium.For this, he shared the 1951 Nobel Prize in Chemistry with Glenn Seaborg.
Berkelium was the fifth transuranium element discovered after neptunium, plutonium, curium and americium. The major isotope of berkelium, 249 Bk, is synthesized in minute quantities in dedicated high-flux nuclear reactors , mainly at the Oak Ridge National Laboratory in Tennessee , United States, and at the Research Institute of Atomic Reactors ...
The Institute for Transuranium Elements (ITU) is a nuclear research institute in Karlsruhe, Germany. The ITU is one of the seven institutes of the Joint Research Centre , a Directorate-General of the European Commission .
Ausenium (atomic symbol Ao) and hesperium (atomic symbol Es) were the names initially assigned to the transuranic elements with atomic numbers 93 and 94, respectively. The discovery of the elements, now discredited, was made by Enrico Fermi and a team of scientists at the University of Rome in 1934.
