摘要
采用多时间分析方法测量和追踪氡活度,以Matlab软件仿真方式,对产生220 Rn及其子体的核脉冲随机序列数据进行多时间分析,结果表明,该方法能够在天然本底和其他本底环境(如222 Rn)的干扰(氡混合场中)情况下有效测量低活度220 Rn的平均浓度。
The kind of multiple time analysis method was used to measure and track the basic principle of radon activity and the corresponding calculation formula. According to random nuclear signal in time a poison distribution, it produces the data of decay pulse serials of radon and its daughters by using matlab and using time interval method analyzed, the results show that the time interval analysis method was effectiveness for measuring the low activity radon events in the high background.
