| Half Life | legth of time for a sample of radiation material to decay |
| Photon | a particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. |
| Alpha Decay | a type of radioactive decay in which an atomic nucleus emits an alpha particle and thereby transforms |
| Beta Decay | electrons ejected from the nucleus when neutrons decay |
| Fusion | join together |
| Fission | split apart |
| Gama Decay | is the release of energy in the form of gamma rays |
| Atom | the basic unit of a chemical element. |
| Wave | a periodic disturbance of the particles of a substance |
| Light Particle | Photon involved |
| Radiation | the emission of energy as EM waves |
