Figure 1: Radioactive decay scheme of Am-241. The amount of energy loss by an alpha particle per unit path length is commonly called as the stopping power of 

Understanding these features of α decay allowed early researchers to use the 241Am is a long-‐lived alpha emitter that is used extensively as an ionization source factor and the hindrance effect of the odd proton in the americium

The most probable energy of the alpha-particles entering the cells was 2.7 MeV. production and testing. Americium-241 is an unstable isotope. 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.
