多时间分析方法测量220Rn的仿真研究

摘要

The kind of multiple time analysis method was used to measure and track the bas-ic principle of radon activity and the corresponding calculation formula .According to ran-dom 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 re-sults show that the time interval analysis method was effectiveness for measuring the low activity radon events in the high background .%采用多时间分析方法测量和追踪氡活度，以M atlab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。
