Optical Radiation

SunsetOptical 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.

UVI 3-day Forecast
Aktuelle UV-Index-PrognoseUV index forecasts are issued every 3 days each year from April to September by BfS, in cooperation with the Federal Environment Agency (Umweltbundesamt), Germany's National Meteorological Service (Deutscher Wetterdienst, DWD) and other associated institutions. The UV index is the internationally standardised measure of the daily peak value of erythemal UV radiation expected to reach the Earth’s surface. The higher the UVI value, the less time it takes for sunburn to occur on unprotected skin. more...

Alliance for UV Protection

The Federal Office for Radiation Protection (Bundesamt für Strahlenschutz, BfS) initiated an interdisciplinary Alliance for UV Protection of experts from science and medicine. This Alliance involves among others the Federal Centre for Health Education (Bundeszentrale für gesundheitliche Aufklärung, BZgA) as well as professionals in radiation protection, cancer research and medicine from various organisations. more...

UV-Strahlung (Video)

UV-Film Unsere Sonne. Ihre Strahlung sorgt für Licht und Wärme und fördert damit das Wohlbefinden. Doch die ultraviolette Strahlung der Sonne kann auch gesundheitsschädlich sein. Sowohl natürliche als auch künstliche UV-Strahlung erhöht das Hautkrebsrisiko. Es hängt davon ab, wann man sich wo aufhält und wie lange.
Das Video "UV-Strahlung" erklärt anschaulich, was UV-Strahlung ist und wie sie wirkt - und gibt Tipps zum UV-Schutz. more...
