摘　　要：本文介绍了一种现场快速对核爆沾染水进行总β放射性监测的方法。测量装置由探头、铅屏蔽体(铅室)、电子学测量仪器及报警装置、自动控制等部分组成,当沾染水的β活度大于军队战时饮用水卫生标准时,越限报警。This article describes a method of quick total β monitoring method of the water contaminated by nuclear explosions. The measuring device is composed of probe head, lead shieding （ lead chamber） , electronic measuring instrument and alarm device and on-line automatic control. An alarm will be triggered when total β radioactivity in the contaminated water exceeds the army war-time potable water hygienic standards.
