Are there building code guidelines for radon in new home construction?

Health Canada has proposed that for newly constructed homes, the guideline should be 100 Bq/m3 or less. To meet that target, under the National Building Code of Canada some measures may be required to prevent radon from entering the home. These measures would include minimizing potential entry routes into the home in the basement floor of foundation walls, proper choice of heating and ventilation that reduce forces that may draw radon into the home, and including provisions for an active soil depressurization system.
