Radioactivity and Nuclear Reactions
... • When an unstable nucleus decays, particles and energy are emitted from the decaying nucleus. • These particles and energy are called nuclear radiation. • The three types of nuclear radiation are alpha, beta, and gamma radiation. ...

... Fission breaks the nucleus into two smaller pieces and often releases one or more extra neutrons. Some of the energy released by the reaction appears as gamma rays and some as kinetic energy of the smaller nuclei and the extra neutrons. ...
