This paper describes a new device and a method to determine the radon diffusion coefficient in damp-proof membranes developed in the Czech Republic. The main advantage of the device is that it enables tests to be carried out in all the known measuring modes used throughout Europe. Two recently developed computer programs are presented for the numerical modelling of the time-dependent radon transport through damp-proof membranes. According to this method, the radon diffusion coefficient is derived from the process of fitting the numerical solution to the measured curve of radon concentration in a receiver container. Numerical simulation and measured data are also compared. Reasons for disagreements between different methods and specific configurations of the measuring device are also discussed.
本文介绍了一种用于测定捷克共和国研发的防潮膜中氡扩散系数的新装置和方法。该装置的主要优点是能够在欧洲各地使用的所有已知测量模式下进行测试。文中给出了两个最近开发的计算机程序，用于对氡在防潮膜中随时间传输的过程进行数值模拟。根据该方法，氡扩散系数是通过将数值解与接收器容器中氡浓度的测量曲线进行拟合的过程得出的。还对数值模拟和测量数据进行了比较。文中还讨论了不同方法和测量装置的特定配置之间存在差异的原因。
