CSP: emission and propagation of radiation associated with a periodically varying electric and magnetic field traveling at the speed of light; radiation characterized by quanta with no mass or charge.,NCI: Radiation that has both electric and magnetic fields and travels in waves. It comes from natural and man-made sources. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.,MSH: Waves of oscillating electric and MAGNETIC FIELDS which move at right angles to each other and outward from the source.,NCI: The radiation of energy as transverse waves produced by moving charges.
