论文摘要
本报告简要回顾了当前保护策略的基本特征，以防止太阳能紫外线造成的健康危害（UV，295-400 nm）。重点是对红斑的重点是最受研究的紫外线伤害，并且紫外线辐照度损坏了脱氧核糖核酸（DNA）分子，这会导致致癌。确定紫外线指数（UVI）的红色加权紫外线辐照度，代表了地球表面上太阳能紫外线辐射水平的共同度量，并且通过使用UVI作为基本参数制作了当前的保护信息。但是，这种方法似乎不足以扎根于针对皮肤癌的信息，考虑到红斑和DNA病变的不同性质。在这种情况下，讨论了过去几年研究的紫外线辐射的其他生物学作用，从而扩大了战略基础。例如，在实践中可以增强UVI定义忽略的光谱UV -A（315-400 nm）频段的重量，因为发现它在DNA损害中起重要作用。此外，可以与某些人习惯一起考虑同时生活方式的特征。
The present report briefly reviews the basic features of the current strategy for the protection against the health harms caused by solar ultraviolet (UV, 295 - 400 nm). The emphasis has been made upon the erythema as being the best-studied UV harm and the ability of UV irradiance to damage the deoxyribonucleic acid (DNA) molecules, which leads to carcinogenesis. The erythemally weighted UV irradiance that determines the ultraviolet index (UVI), represents a common measure of the solar UV radiation level at the Earth's surface and the current protective messages have been made by using UVI as a basic parameter. However, such an approach seems insufficiently grounded to be used also in the messages against the skin cancer, bearing in mind the different nature of the erythema and DNA lesions. In this context, an enlargement of the strategy basis by including additional biological effects of UV radiation studied during the past years has been discussed. For instance, the weight of the spectral UV-A (315 - 400 nm) band that in practice had been neglected by UVI definition can be enhanced since it was found to play an important role in DNA damaging. In addition, features of the contemporaneous life style can be taken into account together with some people habits.
