ISO-11665-12 › Measurement of radioactivity in the environment - Air: radon-222 - Part 12: Determination of the diffusion coefficient in waterproof materials: membrane one-side activity concentration measurement method
The following bibliographic material is provided to assist you with your purchasing decision:
This document specifies the method 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 which will be met during the test.
The test method described in this document allows to estimate the radon diffusion coefficient in the range of 10-5 m2/s to 10-12 m2/s[8][9] with an associated uncertainty from 10 % to 40 %.
