      Short wave UVC

      The wavelength ranges from 100 to 280 nanometers, also known as short wave sterilized ultraviolet radiation. Its penetration ability is the weakest, and the shortwave ultraviolet rays contained in sunlight are almost completely absorbed by the ozone layer before reaching the ground.

      Precautions for using UVC:

      The use of UVC should be kept away from eyes and skin

      Although some studies have shown that only the 280nm wavelength band in UVC cannot penetrate the skin stratum corneum (commonly known as dead skin) and will not cause damage to the human body.

      But prolonged exposure may cause skin cancer. Illuminating the eyes can damage the cornea and cause cataracts.
