New definitions of the radon resistance and radon transmittance of waterproofing materials are introduced. They are based on the real steady-state radon distribution within the materials. Both quantities can therefore be considered as suitable parameters for the design of radon-proof insulations. A comparison between the existing definitions and the new definitions of radon resistance showed that the existing definition significantly underestimates the real radon resistance for a thickness to diffusion length ratio >0.8. It has also been proven that materials with different radon diffusion coefficients but with the same thickness to diffusion length ratio do not have the same radon resistance.
介绍了防水材料氡气抗性和氡气透过率的新定义。它们基于材料内部真实的稳态氡气分布。因此，这两个量都可被视为防氡绝缘设计的合适参数。现有氡气抗性定义与新定义之间的比较表明，对于厚度与扩散长度之比>0.8的情况，现有定义显著低估了实际的氡气抗性。还证明了具有不同氡气扩散系数但厚度与扩散长度之比相同的材料，其氡气抗性并不相同。
