高能电子束辐照可以有效去除饮用水中的三卤甲烷。该过程在流速为120gpm的1.5mev可变电流（0-50ma）电子束系统和60Coγ源上进行了演示。在四种三卤甲烷中，氯仿是最难去除的，即能耗高。溴化三卤甲烷的销毁效率更高。有机结合卤素转化为卤化物阴离子，未观察到有机卤素或氧卤素反应副产物。包括41个参考文献、表格、图表。

High-energy electron-beam irradiation was shown to be efficient for removing trihalomethanes (THMs) from drinking water. The process was demonstrated on a 1.5 MeV variable-current (0-50 mA) electron-beam system at flow rate of 120 gpm and on a 60Co gamma source. Of the four THMs, chloroform was the most difficult, i.e., energy-intensive, to remove. The brominated THMs were much more efficiently destroyed by the process. Organically bound halogens were converted to halide anions, and no organic halogen or oxyhalogen reaction byproducts were observed. Includes 41 references, tables, figures.
