Americium 241 alpha decay

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. Lead-210 decays by alpha or beta decay. The equation for the alpha decay of 210Pb is: 82210Pb --> 80206Hg + 24He representing the alpha 241Am (Americium) Americium is a man made radioactive isotope, and is commonly found in smoke detectors. The source is an alpha emitter, and in the decay process it also kicks out a gamma at 59.6KeV.

The atomic number and mass number of Americium -241 are Z =95 Z = 95 and A= 241 A = 241 respectively. It can be referred from a periodic table that the element Initial experiments yielded four americium isotopes: 241 Am, 242 Am, 239 Am and 238 Am. Americium-241 was directly obtained from plutonium upon absorption of two neutrons.

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. 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 … References since cut-off: 241Am decay from 1994-98 (NSR) Decay properties: Mode.
