Beta Radioactivity

Beta Radioactivity
In this example, 66Ge beta decays into 66Ga. A proton (marked by the arrow) converts into a neutron emitting a positron (positively charged electron) and a neutrino, an extremely light particle which removes energy from the system. The half-life of the ground state of 66Ge is 2.26 hours. The "daughter" nucleus 66Ga, is also radioactive and will beta decay to the stable nucleus 66Zn with a half-life of 9.49 hours.
