Vapour barrier membranes are often used as soil gas retarder in building construction. While vapour permeance characteristics of these membranes are well known and specified in Canadian standards, their radon diffusion coefficients are yet not available. This study provides test results of radon diffusion coefficients for 10 vapour barrier membranes commonly used in Canadian building construction.
防潮膜在建筑施工中常被用作土壤气体阻滞剂。虽然这些膜的透汽性能在加拿大标准中有明确规定且广为人知,但其氡扩散系数尚无相关数据。本研究给出了加拿大建筑施工中常用的10种防潮膜的氡扩散系数测试结果。
