Alpha decay or α- decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus ) and thereby transforms or ‘decays’ into a different atomic nucleus with a mass number that is reduced by four and an atomic number that is reduced by two. An alpha particle is identical to the nucleus of a helium-4 atom which consists of two protons and two neutrons.

Americium-241 (241 Am Am-241) is an isotope of americium.Like all isotopes of americium it is radioactive with a half-life of 432.2 years. 241 Am is the most common isotope of americium as well as the most prevalent isotope of americium in nuclear waste.It is commonly found in ionization type smoke detectors and is a potential fuel for long-lifetime radioisotope thermoelectric generators …
