Results of novel theoretical approaches show a possible underestimation of building materials contribution to indoor radon levels
Published 2025-02-01“…The simplified approach has been shown to provide accurate results—the error on radon activity concentration is below 10%—when the pressure gradient across the building structure is negligible and the building material radon diffusion length is low, so for partition walls. For perimetral walls, especially when the pressure-gradient across the building envelope is not negligible and for high permeable building materials, the simplified approach may return even severe (about 50%) underestimation of the resulting radon activity concentration indoors.…”
