γ射线放射法测量料位高度

Measuring liquid level with γ-ray

利用核物理实验平台,完成了运用γ射线放射法测量料位高度实验,使用自来水当作物料模拟日常生产应用中料位计的使用过程.通过对实验得到的探测器高度与全能峰计数、峰总计数的关系曲线的各点斜率图的分析,实现了非接触测量液面高度.将该实验引入教学中,可打破学生谈核色变的错误想法,培养学生对近代物理实验的兴趣与探究能力.

The nuclear physics experiment platform was used to do the experiment of measuring the liquid level by using radioactive method.Tap water was used as the material to simulate the use of the level gauge in daily production applications.Through the analysis of the slope of the relationship curve of total energy peak count and total peak count with the height of the detector,the non-contact measurement of the liquid level was realized.The experiment could be introduced into the teaching to cultivate students’ interest and exploration ability in modern physics experiments.
