It is the second most stable isotope with a half-life of 432.6 years. In fact, the alpha particles emitted by the Americium 241 in smoke detectors have a short range.

The decay process continues until stable bismuth is formed. The radiation from the decay of americium-241 and its daughters is in the form of alpha particles, beta particles, and gamma rays.

The complete decay of Am 241 involves (successively) α, α, β, α, α, β, α, α, α, β, α and β production. 1. The isotope that undergoes the first β particle emission  11 Nov 2011 Am is naturally radioactive. It decays by emitting alpha particles of about 5 MeV ( 8.01 x 10-13 Joules) energy.
