Where not to place a radon detector
Health Canada wants the normal occupancy area of the lowest lived-in level: a room someone uses more than four hours a day. Bedroom, living room, family room, playroom. Not the bathroom, kitchen, laundry room, closet, cupboard, sump, crawl space or a nook in the foundation.
Height: 0.8 to 2 m from the floor, at least 50 cm from the ceiling and 20 cm from other objects, about 40 cm from an interior wall. Away from HVAC vents, doors, fans, windows, fireplaces, direct sun and electronics. A detector on the fridge is not the guide.
The basement is a test location only if it is used more than four hours a day, or it is about to be. Where to place it. The garage.
References: Health Canada, radon: what you need to know and the 200 Bq/m³ guideline. The two-year window between 200 and 600, and the one-year window above 600, come from Health Canada’s guide for radon measurements in homes.
The 4-day test is a first reading. The 91-day test covers the minimum of three months Health Canada asks for. Both are $59 before tax. Shipping, the prepaid 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 for testing and for installation, and ships kits across Canada.
