Between 200 and 600 Bq/m³ act within two years
Health Canada’s guide for measurements in homes says: between 200 and 600 Bq/m³, take steps to reduce radon within two years. Above 600, within a year. The higher the level, the sooner you act. There is no risk-free level under 200.
The usual fix is a fan that pulls under the slab. The price changes with the sump, the slab and the pipe route, not with the slogan “two years.” While you wait, opening the windows for an hour a day does not create an average under 200. What happens next. What changes the price.
Reference points: Health Canada, what you need to know about radon and the 200 Bq/m³ guideline. The two-year timeline between 200 and 600, and one year above 600, comes from Health Canada’s guide for radon measurements in homes.
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.
