Best Radon Testing & Mitigation in Lethbridge
About Radon in Lethbridge, Alberta
Last updated: March 2026
Lethbridge is served by C-NRPP certified radon professionals listed on RadonFinder.ca. Alberta is the most heavily tested province in Canada for radon. The 2024 Cross-Canada survey, which covered nearly 20,000 Alberta homes, found that roughly one in six exceeds the national guideline of 200 Bq/m³, in line with the national average. The province's geology, dominated by uranium-bearing sedimentary rock and glacial soils, combined with cold winters that keep homes tightly sealed, creates ideal conditions for radon accumulation.
