Few studies in China have examined personal ultraviolet radiation (UVR) exposure using polysulfone dosimetry.
In this study, 93 mother and adolescent child pairs (N = 186) from two locations in China, one rural (higher latitude) and one urban (lower latitude), completed 3 days of personal UVR dosimetry and a sun/clothing diary, as part of a larger pilot study.
The average daily ambient UVR in each location as measured by dosimetry was 20.24 Minimal Erythemal Doses (MED) in the rural location and 20.53 MED in the urban location. Rural mothers had more average daily time outdoors than urban mothers (5.5 h, compared with 1.5 h, in urban mothers) and a much higher daily average personal UVR exposure (4.50 MED, compared with 0.78 MED in urban mothers). Amongst adolescents, rural males had the highest average daily personal UVR exposure, followed by rural females, urban females and urban males (average 2.16, 1.05, 0.81, and 0.48 MED, respectively).
Although based on small numbers, our findings show the importance of geographic location, age, work/school responsibilities, and sex of the adolescents in determining personal UVR exposure in China. These results suggest that latitude of residence may not be a good proxy for personal UVR exposure in all circumstances.
在中国，很少有研究使用聚砜剂量计来检测个人紫外线辐射（UVR）暴露。
本研究中，来自中国两个地点（一个农村[高纬度]和一个城市[低纬度]）的 93 对母亲和青少年（N=186）完成了 3 天的个人 UVR 剂量测定和阳光/衣物日记，这是一项更大的试点研究的一部分。
通过剂量计测量，每个地点的平均每日环境 UVR 分别为农村地区 20.24 最小红斑剂量（MED）和城市地区 20.53 MED。农村母亲每天户外活动的平均时间比城市母亲多（5.5 小时，而城市母亲为 1.5 小时），每天的个人 UVR 暴露量也高得多（4.50 MED，而城市母亲为 0.78 MED）。在青少年中，农村男性的平均每日个人 UVR 暴露量最高，其次是农村女性、城市女性和城市男性（平均分别为 2.16、1.05、0.81 和 0.48 MED）。
尽管基于少数样本，但我们的研究结果表明地理位置、年龄、青少年的工作/学习责任和性别在确定中国个人 UVR 暴露中的重要性。这些结果表明，居住纬度在所有情况下可能都不是个人 UVR 暴露的良好替代指标。
