  Optical Radiation
Optical radiation is part of the electromagnetic spectrum. It is subdivided into ultraviolet radiation (UV), the spectrum of light visible for man (VIS) and infrared radiation (IR). Optical radiation may produce positive as well as negative effects. It is therefore necessary to arrange for reasonable exposure to optical radiation. Primarily UV-radiation, but also IR-radiation, may be both beneficial and detrimental for man. The natural source of both types of radiation is sun. Artificial sources of UV-radiation are among others UV-lamps or emitters as for example in solaria. Artificial IR-radiation is generated by devices such as light bulbs or radiant heaters.
Excessive exposure to natural or artificial UV-radiation means immediate (acute) and long-term (chronic) damage to the eye and skin. Excess of IR-radiation may also cause health detriment. Recent studies have shown that chronic exposure to IR-radiation alone or combined with UV-radiation may induce skin damage. It is therefore necessary to arrange for reasonable exposure to optical radiation.

Wirkung künstlicher UV-Strahlung
|
|
Die künstlich erzeugte UV-Strahlung unterscheidet sich nicht in ihrer Wirkungsweise von der natürlichen UV-Strahlung. Entsprechend können bei Nutzung von Solarien akute und chronische Schädigungen der Augen und der Haut auftreten, wie sie von einer erhöhten Bestrahlung durch die Sonne bekannt sind.
