Electromagnetic Radiation (Disasters) .
Radiations generated by the movement of electric charges or by energetic electronic transitions between various quantic states of atoms, molecules or nuclei. They include a very wide range of radiations, which differ only in their wave lengths; in decreasing order these wavelengths, are the the hertzian waves, the infrared waves, visible light, the ultraviolet waves, the X rays and the gamma radiation (Material IV - Glosario de Protección Civil, OPAS, 1992) .

An electronic system of transmitting such images together with sound over a wire or through space by apparatus that converts light and sound into electrical waves and reconverts them into visible light rays and audible sound. (From Webster, 3rd ed) .
