New technology could add another layer of protection against the next pandemic by simply turning on a light. Researchers are exploring a new way of using ultraviolet light to make indoor air safer.
“It’s been known for 80 years or so that ultraviolet light can kill bacteria and inactivate viruses in the air so that they’re no longer infectious,” Don K. Milton, professor of occupational and environmental health at the University of Maryland School of Public Health, told CBS News.
Conventional UV-C light has been used extensively in places like hospitals, homeless shelters and prisons. But that conventional UV light can damage the skin and eye, so should not be shined directly at people.
