Americium-241 has an alpha decay associated with gamma.
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
The alpha decay of americium-241 produce neptunium-237.
Emitting alpha particles Am-241 decay to Np-237.
For example americium-241 decay to neptunium-237 and americium-243 decay to neptunium-239.
The intermediate product is neptunium 237 ( a very long-lived radioisotope).
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
The alpha decay of americium-241 produce neptunium-237.
The decay product of Am-241 is Np-237.
Emitting alpha particles Am-241 decay to Np-237.
For example americium-241 decay to neptunium-237 and americium-243 decay to neptunium-239.
The nuclear reactions are:Pu-239(2n, gamma)Pu-241(beta)Am-241
The intermediate product is neptunium 237 ( a very long-lived radioisotope).
Americium is a transuranic radioactive chemical element that has the symbol Am and atomic number 95.Its most common isotopes are 241Am and 243Am.241Am decays by emission of an Alpha particle to 237Np; the half-life of this decay is 432.2 years. 241Am95 (by Alpha decay) ------ 237Np93Refer to link below for more information.
The term "used" is not adequate. The radioactive decay of Am-241 is associated with the emission of alpha particles and gamma rays.
The reaction is:Pu-239-------2n,gamma--------→Pu-241------beta---------→Am-241
It's usually americium-241. It undergoes alpha-decay with a half-life of about 400 years. Am-241 is artificially manufactured; it doesn't occur in nature.
The half life of americium 241 is 432,2 years.
