Ultraviolet (UV) radiation is part of the electromagnetic spectrum emitted by the sun. Whereas UVC radiation (wavelengths of 100–280 nm) is absorbed by the atmospheric ozone, most radiation in the UVA range (315–400 nm) and about 10% of the UVB radiation (280–315 nm) reach the earth’s surface. Both UVA and UVB are of major importance to human health.
