radioisotope - Isotopes of atoms that have unstable nuclei and emit radiation to attain more stable atomic configurations., radioactive decay - A spontaneous process in which unstable nuclei lose energy by emitting radiation., alpha particle - A particle with two protons and two neutrons and is emitting radioactive decay., beta particle - A high-speed electron with a 1- charge that is emitted during radioactive decay., gamma radiation - High energy radiation that has no electrical charge and no mass, is not deflected by electric or magnetic fields and accounts for most of the energy lost during radioactive decay., nuclear fusion - The process of binding smaller atomic nuclei into a single, larger, and more stable nucleus., nuclear fission - The splitting of a nucleus into smaller, more stable fragments, accompanied by a large release of energy., half-life - The time required for one-half of a radioisotope's nuclei to decay into its products.,
