Abstract
A radiation shield for promoting direct pigmentation of human skin by solar radiation comprising a filter made from a plurality of layers of synthetic plastic, e.g., polyester or inorganic glass, each filtering different ranges of wave lengths. Substantially all wave lengths below 320 nm and above 450 nm are filtered out so that rapid tanning of the skin is effected without burning.
Claims12
A radiation shield for promoting direct pigmentation of human skin by solar radiation comprising a solid translucent material including finely ground inorganic filter glass particles, which filter glass normally and also when included as said particles in combination with said solid translucent material filters out all wave lengths shorter than 320 nm, blocks wave lengths over 450 nm and which permits maximum transmission of wave lengths in the range of 320 to 450 nm.
