   4. Radiation
      1. Gamma γ

         Nota:

         • Electromagnetic wave. No mass or charge. Emitted when the nucleus has too much energy (E) following α or β decay.
      2. Alpha α

         Nota:

         • Helium Nucleus (2p, 2n) The daughter nucleus may be stable or unstable.
      3. Beta β

         Nota:

         • High energy electron. During decay, a neutron becomes a proton. The β particle is produced at the point of change and is emitted immediately. It occurs when there are too many neutrons in a nucleus.
