Americium-241
Americium-241 (241Am, Am-241) is an isotope of americium. Like all isotopes of americium, it is radioactive, with a half-life of 432.2 years. 241Am 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 (RTGs). Its common parent nuclides are β− from 241Pu, EC from 241Cm, and α from 245Bk. 241Am is fissile and the critical mass of a bare sphere is 57.6–75.6 kilograms and a sphere diameter of 19–21 centimeters. Americium-241 has a specific activity of 3.43 Ci/g (curies per gram or 126.8 gigabecquerels (GBq) per gram). It is commonly found in the form of americium-241 dioxide (241AmO2). This isotope also has one meta state, 241mAm, with an excitation energy of 2.2 MeV and a half-life of 1.23 μs. The presence of americium-241 in plutonium is determined by the original concentration of plutonium-241 and the sample age. Because of the low penetration of alpha radiation, americium-241 only poses a health risk when ingested or inhaled. Older samples of plutonium containing 241Pu contain a buildup of 241Am. A chemical removal of americium-241 from reworked plutonium (e.g. during reworking of plutonium pits) may be required in some cases.
