Americium-241 is an unstable isotope. As americium decays, it releases radiation and forms “daughter” elements. The first decay product of americium-241 is neptunium-237, which also decays and forms other daughter elements. The decay process continues until stable bismuth is formed. The radiation from the decay of americium-241 and its …nature, americium (as the isotope americium-241) was artificially produced from plutonium-239 (atomic number 94) in 1944 by American chemists Glenn T. Seaborg, Ralph A. James, Leon O. Morgan, and Albert Ghiorso in a nuclear reactor.

Je charakterizováno 20 izotopů, z nichž jsou nejstabilnější 243 Am s poločasem rozpadu 7364 let a 241 Am s poločasem 432,6 let. Work by the UK's National Nuclear Laboratory (NNL) to recover americium-241 from the UK's ageing civil plutonium stockpile under a contract with the European Space Agency (ESA) raises some interesting issues, writes Ian Hore-Lacy.

AMERICIUM-241 SDS details show. We provide AMERICIUM-241 safety data sheets view and download at Echemi.com. Americiul poate fi produs în cantități de câteva kilograme, având și unele aplicații practice. Astfel, o mică (0,2 mg) cantitate de americiu 241 este folosită într-un tip de detector de fum ca sursă de radiație ionizantă. De asemenea, americiul 241 este utilizat ca sursă portabilă de raze gama pentru aparate radiologice.
