Which type of decay has the greatest mass?

The type of decay which has the greatest mass is the alpha decay. An unstable nucleus loses the most mass if the nucleus emits an alpha particle. This type of decay has the largest mass among the radioactive decay. When this particle is emitted from a nucleus, it loses two protons and two neutrons therefore large amount of mass is lost.
