Far uvc light safely kills airborne coronaviruses study finds date. Some vendors have combined far uvc visible. This is because due to its strong absorbance in biological materials far uvc light cannot penetrate even the outer non living layers of human skin or eye. Far uvc light has the potential to be a game changer said professor of radiation biophysics and director of columbia s center for radiological research david brenner it can be safely used.

Germicidal efficacy and mammalian skin safety of 222 nm uv light. Uv c light takes a long time to be effective. Providing 99 9 disinfection of occupied spaces at 222nm uv c wavelength. A type of ultraviolet light called far uvc which is.

Far uvc light 222 nm efficiently inactivates bacteria without harm to exposed mammalian skin. Elsewhere one recent study out of columbia university looked at far uvc light that shines at a less intense wavelength still strong enough to zap viruses but potentially incapable of. The sensitivity of the coronaviruses to far uvc light suggests that it may be feasible and safe to use overhead far uvc lamps in occupied indoor public places to markedly reduce the risk of person to person transmission of coronaviruses as well as other viruses such as influenza.
