Radiation Definition. Radiation is the emission and propagation of energy in the form of waves, rays or particles. Examples: A burning candle emits radiation in the form of heat and light. Uranium-238 decaying into Thorium-234 emits radiation in the form of alpha particles. Electrons dropping from one energy state to a lower state emit radiation in the form of a photon.
