1. Electromagnetic energy propagated from a source by
radiation or conduction. (
188 )
Note: The emission may be either desired or undesired and may occur anywhere in the
electromagnetic spectrum.
2. Radiation produced, or the production of radiation, by a
radio transmitting
station. For example, the energy radiated by the local
oscillator of a radio receiver would not be an emission but a radiation. [
