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 .
Americium-243 has a mass of 243.06138 g/mol and a half-life of 7,370 years, the longest lasting of all americium isotopes. It is formed in the nuclear fuel cycle by neutron capture on plutonium-242 followed by beta decay . [ 15 ]
Americium compounds are compounds containing the element americium (Am). These compounds can form in the +2, +3, and +4, although the +3 oxidation state is the most common. The +5, +6 and +7 oxidation states have also been reported.
Americium can be obtained from the reaction of metallic americium with nitrogen or ammonia at 750–800°C: [2]. 2Am + N 2 → 2AmN 2Am + 2NH 3 → 2AmN + 3H 2 [3]. It can also be obtained from the reaction of americium trihydride (AmH 3) with nitrogen at 750 °C: [4]
Americium dioxide is the most widely used americium compound in ionising smoke detectors. The dioxide form is insoluble in water, making it relatively safe to handle in production. In the late 2010s, americium dioxide has been of interest to ESA as power source for radioisotope thermoelectric generators (RTGs) for deep space exploration ...

Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
