Japanese Firm and Columbia University Develop 1st Safe UV Lamp to Kill Coronavirus

Scientists have developed an ultraviolet lamp that effectively kills the coronavirus without harming humans. Ushio Inc., a Japanese light equipment manufacturer, teamed up with Columbia University to create the Care 222 UV lamp, the first of its kind that can be used to disinfect occupied spaces where people are coming in and out. The company said, according to Japan Today, that it is ideal for buses, trains, elevators, and offices, where the risk of the coronavirus is high.

While UV lamps have been used widely to disinfect and sterilize medical and food processing equipment, conventional UV rays, which are 254 nanometers long, can cause skin cancer and eye problems in humans. The new lamp uses UV rays of 222 nanometers, which effectively kill germs but are safe for people, so it can be used in occupied spaces.

According to Fox News, cruise ships are considering the use of the use of UV lights to sterilize their vessels. New York City transit officials announced last May that that they are launching a pilot program to use UV light to disinfect their vehicles to eradicate the COVID-19 virus from their fleet of subway trains and buses.

According to the New York Post, the UV rays from the new lamp destroy 99% of viruses and bacteria in the air and on 32 square feet of surfaces within minutes. As of now, Ushio says it will only provide the lamp to medical institutions.
