Reading this page

In Winkler, the published mean indoor radon reading is 256.7 Bq/m³, based on Health Canada survey sampling from 99 home readings in the Winnipeg metropolitan area. 47.5% of tested homes in this sample exceed the 200 Bq/m³ guideline, and the highest single reading recorded was 1220 Bq/m³.

Local geology is recorded as mixed. Geology helps explain regional averages; individual homes still vary with foundation type, ventilation, and soil contact, so a moderate regional average does not rule out a high reading in any single home.

How to read this

Figures come from Health Canada's Cross-Canada Survey of Radon Concentrations in Homes: long-term tests in participating dwellings, aggregated by geography. The 200 Bq/m³ guideline applies to the normal occupancy area (lowest lived-in level). A city mean is not a reading for your address.

Start with the mean and the share of homes at or above 200 Bq/m³, then check whether this page is labeled direct or regional. Direct means the survey geography matches this municipality or its named metro breakout. Regional means you are seeing a broader area average that may not match your street. Compare with the provincial reading only as context; house-to-house variation is usually larger than city-to-city gaps.

Prefer a three-month (or longer) alpha-track test that includes heating season. Short-term tests are screening tools. Place the detector on the lowest lived-in level, away from exterior walls and high airflow. For elevated results, hire a C-NRPP measurement or mitigation professional, then retest after any work.

Mixed beneath Winkler

Winkler sits on Mixed bedrock or surficial deposits. Radon enters homes through cracks in foundations, sump pits, and utility penetrations. Geology explains regional averages, but individual home levels depend on construction, ventilation, and soil contact.

Mitigation recommended

Average indoor radon in this area exceeds Health Canada's 200 Bq/m³ reference level. If your home tests high, hire a C-NRPP certified mitigator.

  • 1Confirm levels with a long-term test kit (minimum 3 months)
  • 2If results exceed 200 Bq/m³, contact a C-NRPP certified professional
  • 3Sub-slab depressurization typically reduces levels by 80–90%
  • 4Retest after mitigation to verify the system works
