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, 16.3% of homes tested in Saskatchewan were above the Canadian guideline of 200 Bq/m³, and 1.0% were above 600 Bq/m³. Weighted by population, Health Canada estimated that 15.7% of people in Saskatchewan 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 Prairies and Northwest Territories: about one in five 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.

Radon test results by community in Saskatchewan
The 100 Radon Test Kit Challenge, run by Take Action on Radon (a Health Canada-funded initiative), gives communities long-term 91-day alpha track tests and publishes a report for each one. These are recent results, mostly from 2019 to 2026, and are a useful local snapshot, but each is based on a limited number of volunteer homes.
| Community | Homes tested | Above 200 Bq/m³ | Report |
|---|---|---|---|
| Caronport | 39 | 46% | |
| Eatonia | 52 | 52% | |
| Edenwold | 69 | 51% | |
| Estevan | 66 | 24% | |
| Eston | 85 | 60% | |
| Miry Creek | 37 | 70% | |
| Weyburn | 117 | 55% |
Highest shares above the guideline (40+ homes tested): Eston (60%), Weyburn (55%), Eatonia (52%).
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 Saskatchewan?
Yes. In Health Canada’s survey, 16.3% of homes tested in Saskatchewan 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 Saskatchewan?
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.
