Ultraviolet C (UVC) is a type of ultraviolet light with wavelengths between 100-280 nanometers (nm).
Ultraviolet (UV) is divided into three categories UVA, UVB, and UVC, depending on its wavelength. The shorter the wavelength, the more harmful the UV radiation. UVC radiation does not penetrate the atmosphere’s ozone layer and does not reach the earth’s surface. UVC radiation can alter the DNA molecule, preventing replication and causing cell death.
