While you wait for radon mitigation
Between 200 and 600 Bq/m³, Health Canada’s guide says act within two years. Above 600, within a year. Airing the house for an hour drops the number while the window is open. It climbs back when the window closes.
If a basement bedroom is very high, sleeping elsewhere cuts hours in the most concentrated air. That is not a repair. The fan under the slab is. An air purifier is not. Windows. 200 to 600.
The 4-day test is a first reading. The 91-day test covers the three-month minimum Health Canada asks for. Both are $59 before tax. Shipping, the return and the lab are included. Tax is extra. The PDF report goes out within 2 business days after the lab receives the detector.
Above 200 Bq/m³, mitigation starts with a quote. Gaz Radon is C-NRPP certified and ships kits across Canada. See the Canada test page.
