Radon control options for new construction in low-rise residential buildings
1 Scope This National Standard of Canada (NSC) addresses requirements for radon control in the design and construction of new, low-rise residential buildings (see Definitions). This Standard provides design criteria, design tools, methods and techniques, and sample construction specifications to minimize radon entry into new homes prior to initial occupancy and prepare for future mitigation measures if deemed necessary after occupancy has occurred. This Standard specifically addresses mitigation techniques for radon emanating from soil gas sources. Units of measure – Quantities and dimensions in this standard are given in SI units with imperial equivalents, given in parentheses. Exclusions This Standard does not address the mitigation techniques for radon from other sources (see Annex D). This Standard does not address the mitigation of radon in existing buildings (see CAN/CGSB-149.12 - Radon mitigation options for existing low-rise residential buildings). This Standard does not address the mitigation of radon in high-rise residential buildings and low-rise, mid-rise or high-rise non-residential buildings (commercial, institutional and industrial). Application to these building typologies is not appropriate and should only be undertaken by registered professionals possessing expertise in reducing radon ingress, or C-NRPP certified practitioners/specialists. The testing and evaluation of a product against this standard may require the use of materials and/or equipment that could be hazardous. This standard does not purport to address all the safety aspects associated with its use. Anyone using this standard has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use.
