In fact, the alpha particles emitted by the Americium 241 in smoke detectors have a short range. They are so weak that they can be stopped by a single sheet of paper. As a result, the level of radioactivity present in Americium 241 smoke detectors is virtually undetectable.

(U.S.S.R.) 45, 1811-1818 (December, 1963) Data from an investigation of the radioactive decay of Am243 and Am241 are presented. New a Americium-241 decays mainly via alpha decay, with a weak gamma ray product.The α-decay is shown as follows: The α-decay energies are 5.486 MeV for 85% of the time (the one which is widely accepted for standard α-decay energy), 5.443 MeV for 13% of the time, and 5.388 MeV for the remaining 1%. Americium–241 is a radioactive isotope used in domestic smoke detectors. Americium–241 has a half-life of 432 years and decays by emitting alpha particles to produce neptunium. What are the values of A and Z in the following nuclear equation for the alpha decay of an americium–241 nucleus?
