Jun 30, 2019

Ultraviolet radiation refers to the light radiation with the wavelength range of 100nm-400nm. Generally, 100nm-280nm is called UVC, 280nm-315nm is called UVB, and 315nm-400nm is called UVA. Among them, the ultraviolet radiation of 100nm-200nm is absorbed by the atmosphere and has no effect on human beings, which is called vacuum ultraviolet radiation. Therefore, the ultraviolet radiation of 200nm-400nm has a major impact on human beings.
