This is about 0.2 micrograms of Am-241, and it emits about 1 microcurie of alpha radiation. These are commonly found in ionizing smoke alarms. Even though
The first isotope of americium produced was americium 241, still the most commonly used form. The Manhattan Project was busy creating plutonium to be used in nuclear weapons, and some plutonium 239 went through a process of capturing extra neutrons to become 240 and then 241, which gave off an electron from the nucleus to turn into americium.

L’américium 241 aurait une masse critique (sphère nue) comprise entre 60 et 100 kg. L’américium 242m a une masse critique très faible (entre 9 et 18 kg), ce qui fait envisager son utilisation comme combustible spatial.
