Far-UVC light safely kills ( or inactivate ) airborne coronaviruses
The researchers found that more than 99.9% of the exposed virus had been killed by a very low exposure to far-UVC light.
Based on their results, the researchers estimate that continuous exposure to far-UVC light at the current regulatory limit would kill 90% of airborne viruses in about 8 minutes, 95% in about 11 minutes, 99% in about 16 minutes, and 99.9% in about 25 minutes.
