Regional results are not your home’s level. Neighbouring homes can have very different radon levels. The only way to know yours is a long-term test.

How to test your home

  • Health Canada recommends a long-term test of at least 91 days, with at least 91 days during the heating season (fall and winter), when radon levels are usually highest.
  • Test the lowest level of the home where someone spends at least four hours a day.
  • Long-term test kits are sold by hardware stores, online and by some health units and lung associations.

If your level is above 200 Bq/m³

The Canadian guideline is 200 Bq/m³ (about 5.4 pCi/L; the U.S. EPA action level of 4 pCi/L is about 148 Bq/m³). If your result is above 200 Bq/m³, Health Canada recommends taking corrective action to lower the level within one year, and hiring a professional certified by the Canadian National Radon Proficiency Program (C-NRPP). The most common fix is sub-slab depressurization: a pipe and fan draw radon from under the foundation and vent it outside.
