Measurement of radioactivity in the environment — Air: radon 222 — Part 13: Determination of the diffusion coefficient in waterproof materials: membrane two-side activity concentration test method

Mesurage de la radioactivité dans l'environnement — Air: radon 222 — Partie 13: Détermination du coefficient de diffusion des matériaux imperméables: méthode de mesurage de l'activité volumique des deux côtés de la membrane

Abstract / 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.
