Resumo
At the beginning of the 1990’s, the first incidents involving nuclear or other radioactive
material were reported mainly in Europe, with the breakdown of the Soviet
Union. At that period, the International Atomic Energy Agency (IAEA) recorded
more than 800 cases of illicit trafficking of nuclear or radioactive materials. Since
then, related cases have became known worldwide, as the contamination by radioactive
source elapsed from a theft in 1987 in Goiânia, Brazil, and the death of Alexander
Litvinenko in 2006 poisoned with the radioactive isotope Polonium-210. As a result
of these and other events, nuclear and radioactive materials have been targeted for
forensic investigations, creating from there the concept of nuclear forensics. Nuclear
forensics mainly focuses on the nuclear or radioactive material and aims to providing
indication on the intended use, the history and even the origin of the material. Uranium
compounds have isotopic or chemical characteristics that provide unambiguous
information concerning their origin and production process. Rare Earth Elements
(REE) are a set of sixteen chemical elements in the periodic table, specifically the
fourteen Lanthanides in addition Scandium and Yttrium. A large amount of uranium is in rare earths deposits, and may be extracted as a by-product. Accordingly, REE
in uranium compounds can be used as an evidence of uranium origin.
