摘要
本文从放射性平衡及理想气体有关定律出发，分析了Ｒｎ－１５０固体氡气源的标定原理，计算了源内含镭量及与之平衡状态下的氡气质量、原子数、体积及其产生的分压。讨论了影响Ｒｎ－１５０固体氡气源分配剂量精度的几种因素，及其误差修正方法。
Scaling principle of Rn-150 solid Source is discussed in the paper according tothe balance of radioactivity element and the law of ideal gas.Radium content in Rn sourceand corresponding radon mass,atomicity and volume under equilibrium have been calculated.Influence of several tactors on does precision of Rn-150 solid Rn source is also analyzed,andcorrect method of the error has been presented.
