"UV light is divided into four groups as measured by wavelength: (1) Vacuum UV with wavelengths from 100 to 200 nanometers, (2) UV-C at 200 to 280 nanometers, (3) UV-B at 280 to 315 nanometers, and (4) UV-A at 315 to 400 nanometers.
The UV-C spectrum (200 to 280 nanometers) is the most lethal wavelength for microorganisms, because it disrupts the bonds in the between the atoms in the chemicals in microorganisms. This range of wavelengths, with 264 nanometers being the peak germicidal wavelength, is known as the Germicidal Spectrum. " Med andra ord verkar UV vid 400 nm värdelöst...
