| Abstract | Ultraviolet radiation is produced by arcs and incandescent sources operating at high temperatures. The envelope of closed sources may filter out most of the ultraviolet radiation produced. Of the transmitted ultraviolet, two portions of the spectrum are of public health interest. Wavelengths between 1900 and 3000 angstroms (far ultraviolet) are mutagenic, and may be lethal to cells. Wavelengths above about 3000 angstroms (near ultraviolet) appear not to be mutagenic, and are lethal at doses which are very high in comparison with lethal doses in the 1900-3000 angstroms range. However, skin cancer may result from repeated near ultraviolet exposure. Penetration of ultraviolet beyond the skin of mammals is negligible. Wavelengths below about 1900 angstroms (vacuum ultraviolet) are absorbed by air and water, so exposure of biological tissue must be performed in vacuo. (Author) |
