| Popis: | New definitions of the radon resistance and radon transmittance of waterproofing materials are introduced. They are based on the real steady-state radon distribution within the materials. Both quantities can therefore be considered as suitable parameters for the design of radon-proof insulations. A comparison between the existing definitions and the new definitions of radon resistance showed that the existing definition significantly underestimates the real radon resistance for a thickness to diffusion length ratio >0.8. It has also been proven that materials with different radon diffusion coefficients but with the same thickness to diffusion length ratio do not have the same radon resistance. |
