摘　　要：氡在氡室中是一种动态稳定状态,为了更准确的监测氡室中氡浓度的变化,文章主要对氡室首次补氡期间氡及子体的平衡状态的变化进行理论推导和平衡系数对FD125监测曲线的影响进行了探讨并进行了修正,取得了比较好的效果,为氡室氡浓度监测曲线修正提供了一种方法。The radon in the radon chamber is in a dynamic steady state. In order to monitor the changes of the concentration of the radon in the radon chamber, this article primarily has a theoretical derivation according to the changes of the balance of the radon and its daughters during the first radon adding time,in addition to this, the article researches the impact of the balance coefficient on the FD125 monitoring curve and amends the impact. It has achieved relatively good results and provided a method of amending the monitoring curve of the radon concentration in the radon chamber.
