People are exposed to solar ultraviolet radiation (UVR) throughout their entire lives. Exposure to UVR is vital but also poses serious risks. The quantification of human UVR exposure is a complex issue. Personal UVR exposure is related to ambient UVR as well as to a variety of factors such as the orientation of the exposed anatomical site with respect to the sun and the duration of exposure. This is mainly determined by personal behaviour. A variety of efforts have been made in the past to measure or model the personal UVR exposure of people and often personal UVR exposure has been expressed as the percentage of ambient UVR. On the other hand, ambient UVR is being monitored at a variety of places and measurements are available even online. This suggests that both the knowledge of personal UVR exposure and measurements of ambient UVR is required. In this paper, a summary on the different methods, which use ambient UVR measurements to estimate personal UVR exposure of people, as well as a few examples, are given. Advantages and disadvantages will be discussed as well as possibilities and limitations. This also includes an overview of appropriate terminology, units and basic statistic parameters to describe personal UVR exposure.

可以根据周围的紫外线辐射测量值估算个人紫外线辐射的暴露量。

人们一生都暴露于太阳紫外线辐射（UVR）中。暴露于紫外线辐射是至关重要的，但也会带来严重的风险。人体UVR暴露的量化是一个复杂的问题。个人UVR暴露与环境UVR以及多种因素有关，例如暴露的解剖部位相对于太阳的方向以及暴露的持续时间。这主要取决于个人行为。过去，已经进行了各种努力来测量或建模人们的个人UVR暴露，并且经常将个人UVR暴露表示为环境UVR的百分比。另一方面，在各个地方都在监视环境UVR，甚至可以在线测量。这表明既需要有关个人UVR暴露的知识，又需要测量环境UVR的知识。本文概述了使用环境UVR测量来估计人们的个人UVR暴露量的不同方法，并提供了一些示例。将讨论优点和缺点以及可能性和局限性。这也包括描述个人UVR暴露的适当术语，单位和基本统计​​参数的概述。
