In vivo validation of the tolerance of high energy UVC radiation.

CORSA

UVC light of wavelength around 254 nm has been used for a long time to disinfect rooms and surfaces. No people should be in the room, as this radiation is harmful to the skin and eyes. The latest studies show that light with a wavelength of less than 240 nm cannot overcome the barrier of the skin, but effectively reduces germs on its surface. In addition to the existing excimer lamps on the market around 222 nm, new LED emitters with wavelengths around 233 nm, but also 270 nm are being developed in the project. These have the potential to destroy harmful germs and viruses without significantly damaging the skin or tissue and could be used in the presence of people in intensive care units, in ambulances etc. for virus reduction or also on the skin for the reduction of multi-resistant germs. Furthermore, they are small and flexible to be successfully applied in ventilation and air purification systems.
