ABSTRACT
More than 99.9% of seasonal coronaviruses present in airborne droplets were killed when exposed to a particular wavelength of ultraviolet light that is safe to use around humans, a new study (next article*) at the Vagelos College of Physicians and Surgeons at Columbia University Irving Medical Center has found.
“Based on our results, continuous airborne disinfection with far-UVC light at the current regulatory limit could greatly reduce the level of airborne virus in indoor environments occupied by people,” says the study’s lead author David Brenner, PhD, Higgins Professor of Radiation Biophysics at Columbia University Vagelos College of Physicians and Surgeons and director of the Center for Radiological Research at Columbia University Irving Medical Center.

It all began when Dr. Brenner dreamt of finding a safe-for-humans UVC wavelength that could inactivate the more than 1,400 harmful pathogens that co-exist with humans.
He, along with hundreds of other scientists, proved that FAR UVC222nm light was safe for humans but deadly to viruses, bacteria, fungi, protozoa, and helminths.
