Abstract: The effect of radiant energy in the sunburn region, about 290 to 320 nanometers, on the human skin is estimated by comparing the color change of a test area having a compound which changes color as a function of the cumulative exposure to such radiation with at least one color standard area which matches the color attained by said test area after exposure to different predetermined quantities of such radiation.

Abstract translation: 通过将具有变化颜色的化合物的测试区域的颜色变化与作为这种辐射的累积暴露的函数的颜色变化进行比较来估计辐射能量在人类皮肤上约290至320纳米的晒伤区域的影响 一个颜色标准区域，其在暴露于不同的预定量的这种辐射之后与所述测试区域获得的颜色相匹配。
