Electromagnetic Radiation 02
Electromagnetic Radiation 02 : Radiation and Radiological Disasters. A form of propagated energy, arising from electric charges in motion, which produces a simultaneous wavelike variation in electric and magnetic fields in space. The highest frequencies (or shortest wavelengths) of such radiation are possessed by gamma rays, which originate from processes within atomic nuclei. As one goes to lower frequencies, the electromagnetic spectrum includes X-rays, ultraviolet light, visible light, infrared light, microwave, and radio waves
