Radioactive Waste: the unstable atoms left over from nuclear reactions in power plants.
Alpha Decay• α-decay is a type of radioactive decay in
which an atomic nucleus emits an alpha particle and thereby transforms (or 'decays') into an atom with a mass number 4 less and atomic number 2 less.
Alpha Decay
Beta Decay• β decay is a type of radioactive decay
in which a beta particle (an electron or a positron) is emitted from an atomic nucleus. The β decay process allows the atom to obtain the optimal ratio of protons and neutrons.
Beta Decay
Gamma Decay• an excited nucleus emits a gamma
ray almost immediately upon formation (a nuclear isomeric transition, however, can also produce inhibited gamma decay with a measurable and much longer half-life).
Gamma Decay

Nuclear Fission Reaction-When the nucleus splits apart into smaller atoms.•Used in nuclear power plants to make electricity.•Releases two new atoms and releases three neutrons (to keep the chain reaction going) •Creates radioactive waste.
