Measurement of radioactivity in the environment. Air: radon 222 - Determination of the diffusion coefficient in waterproof materials: membrane two-side activity concentration test method Ingestion-build-48974 Additional terminology1 Scope This document specifies the different methods intended for assessing the radon diffusion coefficient in waterproofing materials such as bitumen or polymeric membranes, coatings or paints, as well as assumptions and boundary conditions that shall be met during the test. This document is not applicable for porous materials, where radon diffusion depends on porosity and moisture content.
