Emitting alpha particles Am-241 decay to Np-237.
Americium-241 has an alpha decay associated with gamma.
The alpha decay of americium-241 produce neptunium-237.
For example americium-241 decay to neptunium-237 and americium-243 decay to neptunium-239.
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
The intermediate product is neptunium 237 ( a very long-lived radioisotope).
Americium-241 has an alpha decay associated with gamma.
The alpha decay of americium-241 produce neptunium-237.
The decay product of Am-241 is Np-237.
For example americium-241 decay to neptunium-237 and americium-243 decay to neptunium-239.
The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
The intermediate product is neptunium 237 ( a very long-lived radioisotope).
The nuclear reactions are:Pu-239(2n, gamma)Pu-241(beta)Am-241
Americium-243 might undergo alpha decay to become neptunium-239, and here is that equation: 95243Am => 93239Np + 24He++ The americium-243 has undergone transmutation to become neptunium-239, and the alpha particle, which is a helium-4 nucleus, can be seen on the tail end of the equation.
Americium-244 undergoes beta decay: 95244Am --> 96244Cm + -10e where -10e is a negative beta particle or electron.
The term "used" is not adequate. The radioactive decay of Am-241 is associated with the emission of alpha particles and gamma rays.
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.
