241. Pu (238. U [α,n] 241. Pu), and its subsequent beta decay. Each of these americium isotopes can also be neutron activated to isotopes up through at least . 246. Am. The amount of any product is a function of the starting mass of either . 238. U or . 239. Pu and the neutron fluence over the activation period balanced by the natural

Write the balanced equation for an alpha particle emission from americium. Ionization smoke detectors usually use a radioisotope, typically americium-241, to ionize air and to detect smoke. In this case americium-241 decays to neptunium-237 and is, in fact, a member of neptunium series.

Americium-241 is an unstable isotope. As americium decays, it releases radiation and forms “daughter” elements.
