The UV-index is an international standard measurement of the strength of erythemogenic ultraviolet radiation. It is often published in the media and then refers to the highest expected UV radiation for that day. The highest UV-index value measured in Iceland is seven. Although this is similar to the maximum values from southern Scandinavia, the average UV-index is lower in Iceland compared to other Nordic countries. Around solar noon the UV index is roughly equivalent to the Standard Erythema Dose (SED). During a bright summer day in Iceland the number of Standard Erythema doses can go as high as 32, but is on average in June around twenty. The typical Icelander gets red after 4-6 SED and it is obvious that during solar noon it is easy to sunburn in Iceland if you stay outside without sun protection.
紫外线指数是对致红斑紫外线辐射强度的一项国际标准测量指标。它经常在媒体上发布，指的是当日预期的最高紫外线辐射强度。冰岛测量到的最高紫外线指数值为7。尽管这与斯堪的纳维亚半岛南部的最高值相似，但与其他北欧国家相比，冰岛的平均紫外线指数较低。在太阳正午前后，紫外线指数大致相当于标准红斑剂量（SED）。在冰岛阳光明媚的夏日，标准红斑剂量的数量可高达32，但6月份的平均剂量约为20。典型的冰岛人在接受4至6个标准红斑剂量后就会变红，显然，在太阳正午时，如果不采取防晒措施而待在户外，在冰岛很容易被晒伤。
