Radon in Yukon: Levels by Health Region

Updated November 2026 · Data: Health Canada Cross-Canada Survey of Radon Concentrations in Homes (2012), 2024 Cross-Canada Survey · Sources

In Health Canada’s national radon survey, 19.6% of homes tested in Yukon were above the Canadian guideline of 200 Bq/m³, and 5.8% were above 600 Bq/m³. Weighted by population, Health Canada estimated that 19.6% of people in Yukon lived in homes above 200 Bq/m³ (national figure: 6.9%). The 2024 Cross-Canada survey, which found radon levels rising across the country, estimates high radon in the Pacific Interior and Yukon: about one in three homes.

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.

Frequently asked questions

Is radon a problem in Yukon?

Yes. In Health Canada’s survey, 19.6% of homes tested in Yukon were above 200 Bq/m³, and the 2024 Cross-Canada survey found radon levels rising nationally. Any home can have high radon, so testing is the only way to know.

What is the radon guideline in Canada?

200 Bq/m³ in the normal occupancy area of a home. If a long-term test is above that, Health Canada recommends fixing the home within one year.

How do I test for radon in Yukon?

Use a long-term test kit for at least 91 days during the heating season, placed in the lowest lived-in level. If the result is above 200 Bq/m³, hire a C-NRPP certified professional.
