Researchers at the National Research Council (NRC) of Canada have been conducting experimental studies related to radon control in buildings since 2011, in collaboration with Health Canada’s National Radon Program. The presentation outlines the research outcomes covering the topics ranging from the impact of active soil depressurization on heating energy consumption and indoor environment, leakage through radon control fan enclosure, performance of passive radon stacks in Canadian homes, to the effectiveness of using heat recovery ventilator for radon control in airtight houses. In order to verify the effectiveness of sub-slab air barrier systems in reducing radon ingress, the NRC has developed the Radon Infiltration Building Envelope Test System (RIBETS) and Radon Diffusion Test Chamber (RDTC). The paper will focus on the testing from the RIBETS and the RDTC, summarizing the Radon Diffusion Coefficient and Radon Resistance results measured from 10 building materials that are used beneath concrete slabs.
