Popis
PD CEN ISO/TS 11665-12:2021
This standard PD CEN ISO/TS 11665-12:2021 Measurement of radioactivity in the environment. Air: radon-222 is classified in these ICS categories:
- 17.240 Radiation measurements
- 13.040.01 Air quality in general
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 %.
