Radon in Manitoba Winnipeg and Brandon are not one reading
Manitoba appears often beside Saskatchewan in public surveys of homes over the guideline. Clay soils, basements, and a long heating season are the practical picture. A utility financing program has existed for mitigation. Confirm it is still open before you budget around it. The test comes first.
What to measure
Health Canada’s guideline is 200 Bq/m³ in a room where people actually spend time. A provincial average, a postal code, and the house next door do not give you that number. The detector goes in the lowest lived-in room.
When
Close the house and heat it. October through April is the useful window for a 91-day test. A 4-day test can answer a deadline. It does not replace the long test when you are deciding on mitigation. See when to test.
If the report is high
Mitigation is not an air purifier and not a season of open windows. How the system works and what changes the price.
The 4-day test is a first reading. The 91-day test is the length Health Canada uses to judge a full heating season. Both are $59 before tax. Shipping, the prepaid return, and the lab are included. Tax is extra. The PDF report is emailed within 2 business days after the lab receives the detector.
Above 200 Bq/m³, the fix is a fan that pulls soil gas from under the slab and exhausts it above the roof. Radon Gas is C-NRPP certified for testing and for mitigation, and ships kits across Canada. Start from the Canada test page.
What the 2009–2011 survey measured in Manitoba
Population-weighted estimate: 19.4% of people in homes above 200 Bq/m³. Raw: 23.7% of homes tested. Winnipeg’s health region was 12.1% of 66 homes. Brandon was 44.3% of 79. Winnipeg, Brandon, the full table.
