详细介绍了一种用于绝对测量220Rn的结构特殊的ZnS(Ag)小闪烁室.并进行了测氡比对实验,得到它对222Rn /220Rn及其子体的探测效率可达到96%以上.通过串接此闪烁室测量管道气体流量,与标准流量计的测量结果比较,误差在5%以内.

A special structure small scintillation cell of absolute measurement 220Rn is described. The detection efficiency measuring 222Rn/220Rn and their daughters is above 96%. Comparing the flow rate in a pipe measured with a standard flow meter and with two small scintillation cell in series, the error is less than or equal 5%. So the small scintillation cell can be used for absolute measurement ...
