ISO/TS 11665-13 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

Popis výsledku v původním jazyce

Radon diffusion coefficient is a parameter that determines the barrier properties of waterproof materials against the diffusive transport of radon. Applicability of the radon diffusion coefficient for radon-proof insulation can be prescribed by national building standards and codes. Requirements for radon-proof insulation as regards the durability, mechanical and physical properties and the maximum design value of the radon diffusion coefficient can also be prescribed by national building standards and codes. As no reference standards and reference materials are currently available for these types of materials and related values of radon diffusion coefficient, the metrological requirement regarding the determination of the performance of the different methods described in ISO/TS 11665-12 and this document, as required by ISO/IEC 17025, cannot be directly met. The authors contributed to the creation of a standard within Technical Committee ISO/TC 85, Nuclear energy, nuclear technologies and radiological protection, Subcommittee SC 2, Radiological protection.
