UVC can kill microorganisms that cause diseases. However, it cannot be used around people because it can cause skin cancer and cataracts. Usually, the UVC from the sun is completely filtered out by the earth's ozone layer, so there is no chance to cause harm to humans. The manufactured conventional sterilization UVC light source uses 265nm-278nm wavelength for sterilization.
