Radon in Gaspé 25.3% of homes in the Gaspésie health region
The Gaspésie–Îles-de-la-Madeleine health region was 25.3% of 174 homes above 200 Bq/m³, and 3.5% above 600. That is the highest Quebec region in the 2012 tables. The Bas-Saint-Laurent next door was 14.0% of 171. Montreal was 6.9%.
Gaspé, Chandler, Sainte-Anne-des-Monts and the Magdalen Islands share a regional line and not a basement. The French page is radon en Gaspésie.
What the percentage does not measure
The survey describes homes recruited in a health region, not your house. The slab, the footing drain, the cracks and how many hours the windows stay shut change the number from one address to the next. The reading that matters is the lowest lived-in room, during the heating season.
If the report is over 200
In that survey, Health Canada asked participants to act within two years between 200 and 600 Bq/m³, and within one year above 600. Next steps: radon above 200. Quebec Montreal
The 4-day test is a first reading. The 91-day test is the length Health Canada uses to judge a 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. Gaz Radon is C-NRPP certified for testing and for mitigation, and ships kits across Canada. Start from the Canada test page.
