Americium's most stable isotope, americium-243, has a half-life of about 7,370 years. Americium-241, with a half-life of 432.2 years, is used in these products because it is easier to produce relatively pure samples of this isotope. Its most important isotope is americium-241 (half-life 432.7 years), which is produced by the beta-decay of plutonium-241. Americium-241 is used commercially in applications such as smoke detectors, thickness gauges, and fluid level gauges. Atomic Number: 95 Mass Number: 241(146 neutrons) Chemical Form: Americium oxide with beryllium metal Physical Form: Compacted mixture of americium oxide with beryllium metal.
