What is UV-C radiation?
Ultraviolet germicidal radiation (UVGI) is a portion of the naturally occurring ultraviolet radiation from solar energy. It is completely absorbed by the ozone layer and does not reach the earth's surface. The current ability to emit UVGI comes only from artificial light sources.
Von allen Strahlungsarten hat UV-C (zwischen 200 und 280 nm) die stärkste Wirkung auf biologische Materialien. So kann UVGI wirksam zur Desinfektion und Dekontamination von Luft und Oberflächen eingesetzt werden, um die Ausbreitung schädlicher Infektionserreger zu verhindern.
How does UV-C inactivate pathogens?
The radiation is naturally absorbed by micro-organisms such as viruses, bacteria and moulds. When UV-C radiation enters the micro-organism, the cell's DNA bonds are broken.
This process changes the inherent characteristics of the cell so that the micro-organism can no longer reproduce. By destroying the organism’s ability to reproduce, it is completely harmless as it cannot colonise, and the micro-organism population quickly decreases.

How to check the effectiveness of UV-C radiation?
We trust the world leader in photochromic indicator technology, INTELLEGO TECHNOLOGIES. With INTELLEGO's patented ink that measures UV-C radiation, dosimeters provide a simple way to monitor and evaluate the effectiveness of the decontamination process. Colour coding on the dosimeter card identifies the UV-C doses acting per mJ/cm2. The colour-changing UVC dosimeters make it easy to validate any UV-C device and provide real-time visible evidence of successful UVGI.
