Abstract
A device for the qualitative measurement of uv radiation received by the skin consists of a laminar strip for application to the skin, the strip including a photochromic material disposed intermediate the ends of the strip and a reference material also disposed intermediate the ends of the strip. The reference material is suitably a dye which matches closely the color of the photochromic material after exposure to a pre-determined quantity of uv radiation. The predetermined quantity of uv radiation corresponds to the maximum exposure tolerable by the particular skin type. The device enables one to visually assess exposure to uv radiation by a direct comparison of the color densities of the photochromic material and the reference material during exposure to sunlight.
