| Mass | Quantity of mass contained in a physical object. We refer to it as weight. |
| Kinetic energy | Energy of motion |
| Chemical energy | Energy that is released by a chemical reaction |
| Thermal energy (heat) | Energy of motion at the molecular level |
| Nuclear energy | energy thats contained inside the nucleus of an atom |
| Natural environmental radiation | terrestrial, cosmic rays, internally deposited radionuclides and radon. |
| Air kerma (Kinetic Energy Released per unit Mass) | The amount of radiation energy released into the air by x-ray. Measures the intensity of energy before it reaches the patient. |
| Absorbed dose | The amount of radiation that is absorbed by the tissues. |
| electron binding energy | the strength of attraction that keeps an electron attached to the atom’s nucleus. |
| Isobar | Atoms that have a different number of protons and neutrons but the same number of nucleons. |
| Isotone | Atoms with different atomic numbers and mass number. |
| Isomer | Atoms with the same atomic number and atomic mass number. |
| Radioactivity | The release of energy and particles from an unstable atom to become stable. |
| Radioactive decay | The process of an unstable nucleus changing into a more stable one by giving off radiation. |
