When you work on a computer or watch TV, your body is easily exposed to electronic radiation. For example, in CRT-based displays, electrons that sweep across the screen generate pulsed electromagnetic radiation (PEMR). Some of this energy is emitted at very low frequencies, producing very low frequency energy.
