In this research, the erythemally effective UV measured using miniaturized polysulphone dosimeters to over 1250 individual body sites and collected over a 4-year period is presented relative to the total exposed skin surface area (SSA) of a life-size manikin model. A new term is also introduced, the mean exposure fraction (MEF). The MEF is used to weight modeled or measured horizontal plane UV exposures to the total unprotected SSA of an individual and is defined as the ratio of exposure per unit area received by the unprotected skin surfaces of the body relative to the exposure received on a horizontal plane. The MEF has been calculated for a range of solar zenith angles (SZA) to provide a sunburning energy data set weighted to the actual SSA of a typically clothed individual. For this research, the MEF was determined as 0.15, 0.26 and 0.41 in the SZA ranges 0°-30°, 30°-50° and 50°-80° providing information that can be used in a variety of different ambient, latitudinal and seasonal climates where total human body UV exposure information is not available.
在这项研究中，使用微型聚砜剂量计测量了超过 1250 个个体部位的红斑有效紫外线，并在 4 年期间进行了收集，相对于真人大小人体模型的总暴露皮肤表面积 (SSA)。还引入了一个新术语，即平均暴露分数 (MEF)。MEF 用于对模型化或测量的水平面紫外线暴露进行加权，以得到个体的总无保护 SSA，并定义为身体无保护皮肤表面每单位面积接收的暴露与水平面上接收的暴露之比。已经为一系列太阳天顶角 (SZA) 计算了 MEF，以提供加权到典型穿衣个体实际 SSA 的晒伤能量数据集。对于这项研究，MEF 在 SZA 范围 0°-30°、30°-50°和 50°-80°分别确定为 0.15、0.26 和 0.41，提供了在各种不同的环境、纬度和季节性气候下可以使用的信息，在这些气候中，无法获得人体总紫外线暴露信息。
