Definition of Radiation:

  1. The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.

  2. Divergence out from a central point, in particular evolution from an ancestral animal or plant group into a variety of new forms.

  3. Particulate emanation of unstable or split atomic nuclei, such as protons or helium nuclei (alpha radiation), high-energy electrons (beta radiation), and neutrons (from fission). It is the ionizing type of radiation that directly breaks down chemical bonds and is likely to be harmful.

  4. Direct transmission of heat or electromagnetic energy through space or another medium. It is the non-ionizing type of radiation that does not affect chemical bonds and thus is usually harmless. Also called radiant energy.
