着重介绍了采用氡析出率测量仪定量确定模型体源氡的有效泄漏比率的简便方法，并介绍了采用中子水分计测量模型体源湿度所考虑的影响因素及其修正的方法。在通过试验确定上述方法后，对全国各地模型体源进行了氡泄漏和湿度测量，使模型体源的量值达到了更高程度的统一。 A simple and convenient method for quantitatively determining the effective leakage rate of radon in model body by radon exhalation rate meter is introduced emphatically. The influential factors and the corrections adopted by neutron moisture meter for measuring body source humidity are introduced. After the above methods were confirmed through experiments, radon leakage and humidity measurements were carried out on the body sources of the models across the country, so that the volume of the model body source reached a higher level of unity.
