A measurement system is described that allows an objective review and evaluation of the amount of use by different population groups of provided shade structures. It employs the comparison of the erythemal UV exposure measured with dosimeters to either the vertex or forehead to that in full sun. The technique has been developed using three shade structures and found to provide a linear relationship with an R(2) of 0.99 between the exposure ratio and the time spent in the shade for the solar zenith angle range of 19-53° and for both low- and high-cloud levels. It provides an objective determination of the amount of shade use by population groups that have set periods of time outdoors.
描述了一种测量系统，该系统允许客观地回顾和评估不同人群对提供的遮阳结构的使用量。它采用比较用剂量计测量的红斑紫外线暴露与顶点或额部的暴露与在全日照下的暴露。该技术已使用三种遮阳结构进行开发，并发现对于太阳天顶角范围为 19-53°以及低云和高云水平，暴露比与在遮阳下度过的时间之间存在线性关系，R（2）为 0.99。它为在户外设定时间段的人群提供了对遮阳使用量的客观确定。
