Thus, the atmosphere blocks about 77% of the Sun's UV, almost entirely in the shorter UV wavelengths, when the Sun is highest in the sky (zenith). Of the ultraviolet radiation that reaches the Earth's surface, more than 95% is the longer wavelengths of UVA, with the small remainder UVB. There is essentially no UVC.

Foodstuffs having low moisture content like carrot, yam or sweet potato is placed inside the box. These foodstuffs help in avoiding the molding of the bran.
