常用氡子体测量方法模拟比较

摘要

介绍了氡子体最小二乘拟合测量法的测量结果,并进行了分析.主要结论是:(1)氡子体最小二乘拟合测量法在不同氡子体间平衡比、不同浓度下,均与期望值偏离较小,测量结果的离散性也较低;(2)托马斯法和库斯尼兹法的PAEC测量结果离散性较低,但与期望值有一定系统偏离;(3)马尔科夫法的测量结果与氡子体间平衡比关系较大.%By simulating radioactive decay process with Mont Carlo method,some common used Radou progeny measuring methods in China are analyzed,that include least square method developed by author of the paper,Thomas Method,Malkov Method and Kusnetz Method.The results show that:1) The least square method matches the expect value closely,and has the least relative standard deviation;2) Thomas Method and Kusnetz Method also have a small relative standard deviation but a relative large deviation from expect value;3) An relative obvious relationship between Malkov Method and the ratio of Radon progeny.
