    UV facts

Ultraviolet light with wavelength shorter than 300 nanometers is extremely effective in killing microorganisms. The most effective sterilizing range of UV is within the C bandwidth (UVC - 253.7nm). This range is called the germicidal bandwidth. UVC, is not known to cause cancer or severe sunburns. It does not penetrate past dead cell layers of the skin, but it may cause eye irritations or burns after prolonged exposure.
