ултраљубичасто (УВ) зрачења

Radiant energy in the range of about 100-380 nanometers (nm). For practical applications, the UV band is broken down further as follows: Ozone-producing - 180-220 nm; Bactericidal (germicidal) - 220-300; Erythemal (skin reddening) - 280-320; "Black" light - 320-400. The International Commission on Illumination (CIE) defines the UV band as UV-A (315-400 nm); UV-B (280-315 nm) and UV-C (100-280 mm).
