A professor from the School of Energy System and Nuclear Science at the University of Ontario Institute of Technology in Canada said that their research on ultraviolet light to prevent the spread of Coronavirus pandemic has achieved more optimistic results, and mentioned that far ultraviolet lamps have significant effects on reducing the spread of viruses in enclosed spaces. effect.
According to Global News Canada, through computer simulation, Professor Kirk Atkinson found that using far ultraviolet rays can kill more than 85% of viruses in the air. He introduced that far-ultraviolet rays are a special kind of ultraviolet rays, and far-ultraviolet lamps are not currently available in people’s daily lives. Researchers said that this lamp is as effective as wearing an N95 mask. In addition to its potential to reduce the spread of the virus, it also has a smaller health impact compared with air purifiers and conventional UV lamps.
Atkinson also said that the air purifier may be equipped with conventional ultraviolet lamps. If this kind of light shines on people’s skin or eyes for a long time, it may cause cancer or cataracts.
Currently, Atkinson is collaborating with researchers to install a far-ultraviolet lamp in a coffee shop in New York for experimental observation. Test the performance of this lamp and its disinfection effect on the environment. Atkinson said that the current lamp can be purchased online, and its price may be as high as 1,000 Canadian dollars (about 5,000 yuan), and this lamp is not produced in Canada.
Atkinson said that because the research and production costs of this lamp are high, only a few manufacturers can make this lamp. Atkinson said that he is discussing with researchers how to make this lamp more affordable so that it can be used in more public places. He said that this lamp is not only effective against the new coronavirus, it will also have a certain inhibitory effect on any kind of virus or bacteria in the future.
