本文提出了一种评价面部红斑性紫外线照射分布和单位面积面部红斑性紫外线照射量的方法，该方法仅使用位于头部顶点、前额、鼻子、下巴、左右耳和左右脸颊的8个剂量计。提供了接受高紫外线照射的面部部分的整体图片。在亚热带纬度，红肿紫外线照射到人脸的分布随时间和云量的变化而变化。在太阳天顶角相似的两天，随着云量的增加，红斑紫外线暴露于鼻部与水平面上的比值从0.47变化到0.84。同时，面部单位面积红斑暴露总量从122 ml cm-2下降到56 ml cm-2。虽然绝对暴露量减少了，但鼻子的暴露量相对较高。
This paper presents a method for the evaluation of the distribution of the facial erythemal UV exposure and the erythemal UV exposure per unit area of the face using only eight dosimeters located on the vertex of the head, forehead, nose, chin, left and right ears and left and right cheeks. An overall picture of the parts of the face receiving high UV exposures is provided. The distribution of the erythemal UV exposure to the human face at a subtropical latitude was shown to change with time of year and with cloud cover. On two days with similar solar zenith angles, the ratio of the erythemal UV exposure to the nose compared with that on a horizontal plane changed from 0.47 to 0.84 with increased cloud cover. At the same time, the total erythemal exposure per unit area of the face dropped from 122 to 56 ml cm-2. Although the absolute exposures decreased, the nose received a relatively high exposure.
