The US study has revealed that ultraviolet (UV) radiation can kill the coronavirus. Scientists found that this kind of UV radiation is more reliable to work on humans and effective disinfection method for public spaces.

The study is published in the American Journal of Infection Control. The Ultraviolet-C (UVC) light with a wavelength of 222 nanometers (nm) will kill the Coronavirus. It cannot penetrate the human skin.

As per the UK researchers along with Hiroshima University in Japan, with the studies with 222 nm UVC well know as Far-UVC.

They have only found the effectiveness in destroying coronaviruses but not on SARS-CoV-2.

The study said, “New studies have revealed that 222-nm UVC is less harmful than 254-nm UVC as far-UVC light has a limited penetration depth in the skin or eyes, and it is also an efficient anti-microbial technology.”

The researchers spread a 100 microliter solvent consisting of the virus on nine-centimetre sterile polystyrene. They let it to dry at a room temperature biosafety place before installing the Far-UVC lamp 24 centimetres over the surface of the plates, the study mentioned.

The research revealed that 99.7 per cent of the SARS-CoV-2 viral production was destroyed in 30-seconds of exposure to 222 nm UVC radiation.
