Hello, Ron!
Radioactive atoms have the energy put into them in several ways:
Understand that any nucleus has a lot of energy in it. Sometimes modification of a nucleus, by a slow neutron, e.g., will cause the original nucleus to become unstable, thus allowing the energy already in that nucleus to be released. Fission of uranium illustrates this; absorbtion of one neutron destabilizes the uranium nucleus, causing it to split and release daughter elements plus additional neutrons. More energy is released than was supplied by the incoming neutron, so the rest must have been inherent in the uranium nucleus. So we must add a 5th source of energy:
