Lecture on Non-ionizing Radiation

Non-ionizing Radiation are electromagnetic waves incapable of producing ions while passing through matter, due to their lower energy. The sun emits radiation composed of high energy infrared radiation, visible light, and ultraviolet radiation collectively known as shortwave radiation (SW). The earth emits radiation composed of lower energy infrared radiation collectively known as long-wave radiation (LW). Some examples on Non-ionizing Radiation Sources: Visible light; Microwaves; Video Display Terminals; Power lines, Lasers etc.
