Introduction to Nuclear Reaction Operations Content December 1988

Radioactive decay is the spontaneous breakup of an unstable nucleus.

The emission of either alpha or beta particles changes the identity of the nucleus due to a loss in nucleon charge.

The emission of a gamma ray simply reduces the energy level of the nucleus.
