ranges from the lower region of visible light (400 nm) to the upper region of X-rays
(10 nm). UV-C is the part of ultraviolet
UV-C light sources emit electromagnetic radiation of 185 and/or 254 nm and can have a germ-reducing
effect. At 185 nm the light induces ozone production. Ozone itself has germ-reducing effects but might
also lead to negative consequences such as irritation or carcinogenic

The time for a defined reduction of germs is evaluated by using the required UV-C dose for a certain
reduction effect and the actual radiation dose of
radiometer between 200 and 270 nm.
Different germs show different sensilivilies towards UV-C radiance. Therefore, the values for the
