NEW YORK: Could a new type of ultraviolet lamp be used in stations, airplanes and schools to kill dangerous viruses, becoming a game changer in the COVID-19 fight?

The New York subway system, following the example of Chinese subways, plans to use ultraviolet lamps to disinfect its trains, but only during nighttime closures. He appeared to be inspired by federal research on the effects of natural light on the virus - but natural light has no UVC rays. The team next plans to test the lamps on viruses suspended in the air, as when an infected person coughs or sneezes.For 40 weeks now, the lab has exposed mice to far-UVC rays for"eight hours a day, five days a week, at intensities 20 times higher than we might think of using with humans."After testing the rodents' eyes and skin,"we have found absolutely nothing; The mice are very happy - and very cute as well," Brenner said.

If UVC lamps have already been in commercial use for two or three years - notably in the diamond industry, where they can be used to distinguish artificial from real gems - potential clients are now legion, say companies producing them.
