The Japanese edition of Mainichi reports that local scientists have created a device that can destroy 99.99% of the COVID-19 virus in just 30 seconds.
The portable device they created emits ultraviolet waves with a wavelength of 280 nanometers and an optical power of 70 milliwatts. The source reports that the virus can be completely destroyed by exposure to ultraviolet radiation with a wavelength of 260 nanometers, while the device will last only 2000 hours. If the wavelength is 280 nanometers, then the service life can be increased by about 10 times.
99.99% of the virus on surfaces is completely eradicated in 30 seconds at a distance of 5 centimeters, according to research conducted by Japan’s Tokushima University.
The creators of the device claim that this gadget can also be used in ventilation and air conditioning systems for air disinfection.
