WHAT IS UV LIGHT?
The light with a wavelength of 10-400 nano meters (nm) in sunlight is called ultraviolet light, and it can be divided into UVA, UVB, and UVC (200nm to 275nm) according to different wavelength bands. Among them C-band ultraviolet rays destroy the DNA of bacteria and RNA of viruses which play an important role in disinfection and sterilization.
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; however, because bacteria and viruses are of micrometer or smaller dimensions, far-UVC can penetrate and inactivate them. for the first time that far-UVC efficiently inactivates airborne aerosolized viruses, with a very low dose of 2 mJ/cm sq of 222-nm light inactivating >95% of aerosolized H1N1 influenza virus. Continuous very low dose-rate far-UVC light in indoor public locations is a promising, safe and inexpensive tool to reduce the spread of airborne-mediated microbial diseases.
The findings suggest that use of overhead far-UVC light in hospitals, doctors’ offices, schools, airports, airplanes, and other public spaces could provide a powerful check on seasonal influenza epidemics, as well as influenza pandemics.
