Ultraviolet radiation
What is UV radiation?The ultraviolet spectrum is divided into ultraviolet-A (UV-A) with a wavelength of 315-400 nm (nanometers), UV-B (280-315 nm) and ultraviolet-C (UV-C) 100-280 nm , which differ in penetrating ability and biological effect on the body.Ultraviolet radiation (UV) is part of the electromagnetic spectrum, like X-rays, radio waves or visible light. For practical reasons, it is divided into the following lengths (λ, wavelength in nanometers).
UV-A radiation is source of sunburn, passes through the stratum corneum.
UV-B radiation is used primarily for therapy.
UV-C radiation has a strong germicidal effect, maximum at a wavelength of 253.7 nanometers. May cause skin burn and inflammation of the retina. Radiation from waves shorter than 200 nm produces ozone. It is harmful, therefore, in our lamps, a special quartz (more precisely, uviolet) glass with a special patented coating is used, thanks to which ozone is practically not formed (a small amount of ozone can be released only in the first 100 hours of operation of the lamps). The range of the prevailing wavelength of our devices is 253.7 nm.
