Yes, UVC light has been shown to inactivate the coronavirus According to many scientific studies and tests performed by several reputable institutions
Ultraviolet (UV) light is produced by the sun and by special lamps. There are three types of UV light—UVA, UVB, and UVC. UVC light includes wavelengths of light from 200 to 280 nanometers. These UVC wavelengths have the most energy of the three types of UV light. Energy from UVC wavelengths is absorbed by, and quickly destroys, the genetic material inside viruses and other microbes, rendering them inactive.
In a few laboratory experiments, UVC light has been found to destroy the ability of the SARS-CoV-2 virus to infect a host (for example, a mouse or a person), another indication that it is effective against germs. UVC light has also been shown to inactivate the genetic material in other coronaviruses.
