Am-241 can be combined with beryllium to produce neutrons. What is it used for? Am-241 is used in some medical diagnostic devices and in a variety of industrial and commercial devices that measure density and Americium is produced by bombarding plutonium, atomic number 94, with neutrons in a nuclear reactor.

Because of the low penetration of alpha radiation, Americium-241 only poses a health risk when ingested or inhaled. Americium-241 decays mainly via alpha decay, with a weak gamma ray byproduct. The α-decay is shown as follows: 95 241 A m 432.2 y 93 237 N p + 2 4 α 2 + + γ 59.5409 k e V {\displaystyle \mathrm {^{241\!\,}_{\ 95}Am\ {\overset {432.2y}{\longrightarrow }}\ _{\ 93}^{237}Np~+~_{2}^{4}\alpha ^{2+}+\gamma ~59.5409~keV} } Am-241,95 -----> He-4,2 (alpha particle) + Np-237,93.

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? ? Mode of decay: Alpha particles and weak gamma radiation. Chemical properties: Crystalline metal that is solid under normal conditions.

As americium decays, it releases radiation and forms “daughter” elements. The first decay product of americium-241 is neptunium-237, which also decays and forms other daughter elements.
