Ultraviolet Sterilization Technique warrior against Covid-19
UV sterilization or Ultraviolet germicidal irradiation (UVGI) is a sanitization method that utilizes shorter or more energetic wavelength ultraviolet (UVC) to kill or inactivate microorganisms so that they could not perform the vital cellular functions. Since 1878, artificially produced UVC has been an effective method of sterilization commonly used in hospitals, airplanes, factories, and offices. Significantly, it is also used in food, water, and air purification.
