Performance and Applied Research of A New Type Detecting System for Radon and α Energy Spectrum Machine

分析了222Rn以及220Rn衰变产生α粒子的过程,以及采用半导体探测器,利用核谱测量技术与嵌入式技术研制的新型测氡仪-α谱仪的基本原理,通过各种测试结果的对比,确定了仪器的基本设计参数。通过对分析方法,标定方法的分析,认为该仪器可以满足连续测氡与瞬时测氡以及α谱测量的要求。可用于室内测氡、壤中测氡、水溶液测氡以及钍射气测量等领域。

Paper analyzes the process of the decay of the 222Rn and 220Rn,and introduces the alpha ray spectrometer based on the nuclear spectrum technology and embedded system technology,using semi-conductor detector.It determined the parameters by comparing results of a few kinds of test.By analyzing measuring method and calibration method involved,paper believes that machine is able to meat the requirements of the continuous and instantaneous radon measurement and alpha measurement.It is also can be used to measure thorium and radon in soil,water,and air.
