This paper presents radon diffusion coefficient values and radon resistance values determined for 650 widely-used waterproofing materials divided into 29 groups according to their chemical composition. The reliability of two different approaches for determining the radon resistance is discussed, and differences between the two approaches are identified. A comparison between the radon resistances of waterproofing materials and the requirements prescribed by various building standards indicates that some requirements are unnecessarily strict. It is shown that the most effective approach for setting the requirements is to prescribe several minimum radon resistance values in dependence on the parameters of the building and the subsoil.
本文提出了 650 种广泛使用的防水材料的氡扩散系数值和氡阻力值，这些材料根据其化学成分分为 29 组。讨论了两种不同方法确定氡阻力的可靠性，并确定了两种方法之间的差异。将防水材料的氡阻力与各种建筑标准规定的要求进行比较表明，有些要求过于严格。结果表明，最有效的方法是根据建筑物和地基的参数规定几个最小的氡阻力值。
