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 consistently records the highest median indoor radon levels of any province in Canada. Health Canada surveys have found that roughly one in four Alberta homes exceeds the national guideline of 200 Bq/m³ — a rate significantly higher than the national average of one in eleven. 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.
