First Proof from Hiroshima University That a Safer UV Light (222 nm UVC also known as Far-UVC) Effectively Kills COVID-19 Virus
An in vitro experiment by HU researchers showed that 99.7% of the SARS-CoV-2 viral culture was killed after a 30-second exposure to 222 nm UVC irradiation at 0.1 mW/cm2. The study is published in the American Journal of Infection Control.Since 254 nm UVC harms exposed human tissues, it can only be used to sanitize empty...
