Radon in Sherbrooke 9.3% in Estrie, from 54 homes
In the Health Canada survey, the Estrie region had 9.3% of homes above 200 Bq/m³, from only 54 homes, and none above 600. Sherbrooke is in that region. So are Magog and the townships. Fifty-four addresses are not a street map.
Quebec’s raw average was 10.1%. Estrie is not an outlier in that table. A single house can be. Estrie. The provinces.
The 4-day test gives a first reading. The 91-day test covers the three-month minimum Health Canada asks for. Both are $59 before tax: shipping, return and the laboratory are included, taxes extra. The PDF report is sent within 2 business days after the laboratory receives the detector.
Above 200 Bq/m³, mitigation is confirmed with a quote. Gaz Radon is C-NRPP certified for measurement and mitigation.
