简要综述了饮用水和废水中生物抗性污染物的辐射诱导分解。首先，一些重要的单位，定义等，辐射源，以及在水中的剂量-深度曲线作为电子能量和Co-60-γ射线的函数。下面是水辐解和初级自由基特性的示意图。然后介绍了几种脂肪族和芳香族氯代化合物在空气中的降解情况。一些光谱和动力学数据的瞬态产生的氯代酚也被引用，以说明和解释相当复杂的降解机制。在这方面，辐射和氧气以及臭氧的协同效应也进行了讨论。最后提出了高能电子束的技术应用方案。
The radiation-induced decomposition of biological resistant pollutants in drinking as well as in wastewater is briefly reviewed. First, some important units, definitions etc., radiation sources, as well as dose-depth curves in water as functions of the electron energy and Co-60-gamma-rays are mentioned. Following is a schematical presentation of water radiolysis and of characteristics of primary free radicals. Then the degradation of some aliphatic and aromatic chlorinated compounds in the presence of air is presented. Some spectroscopic and kinetic data of transients resulting from chlorinated phenols are also quoted in order to illustrate and to explain the rather complicated degradation mechanisms. In this respect the synergistic effect of radiation and oxygen as well as that of ozone is also discussed. Finally, a scheme for technical application of high energy elelctron beam is presented.
