Radon and children the nap room and the bedroom, not a special device
A child does not have a separate “children’s radon.” A child has more years of exposure ahead if the bedroom is high, and spends the night in one specific room. Health Canada defines an occupied zone as a place where a person stays more than four hours a day. A basement playroom meets that definition. A corridor does not.
The detector goes in the lower bedroom or the playroom, at breathing height, not on the window sill and not in the closet. If the children sleep on the second floor and nobody stays in the basement, still test the family’s lowest lived-in level, then you can add the bedroom.
School does not replace the house
A day at school and a night in a basement bedroom are two buildings. Daycare. Where not to place the detector.
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.
