| Alpha particles | a wave of energy traveling as particles that contain two protons and two neutrons |
| Beta particles | a wave of energy as an electron is given off by a radioisotope. |
| Gamma rays | waves of energy given off by radioisotopes |
| Isotopes | atoms of the same element with different numbers of neutrons |
| Nuclear fission | splitting the nucleus of an atom into smaller pieces |
| Nuclear fusion | the bonding of isotopes with a smaller mass to create an atom with a greater mass and produces energy |
| radiaiton | the transfer of energy by waves as particles are released from |
| radioactive decay | when a radioactive atom releases particles from the nucleus and it changes into an atom of another element |
| radioisotopes | isotopes of radioactive elements |
| X-ray | energy produced by slowing down a beta particle. |
