| 摘 要： | 对衡水某土坯房居室内220Rn浓度及其子体平衡当量浓度（EECTn）进行了累积测量和瞬时测量，通过计算得到居室内距各发射源不同距离的220Rn平衡因子FTh。室内不同位置处累积测量和瞬时测量的FTh范围分别为0.003～0.065和0.008～0.045,平均值为0.03。结果表明，220Rn平衡因子的空间分布具有一定规律性。

| Abstract: | Passive method and positive measurement were used to measure 220Rn and its daughters equilibrium equivalent concentrations(EECTn),and equilibrium factors of 220Rn for different distances from different sources were calculated based on the mea-surement.The equilibrium factors of 220Rn are 0.003-0.065 by passive measurement and 0.008-0.045 by positive measurement,respectively.The equilibrium factor of 220Rn appears a certain regular change in the spatial distribution. |
