Radon testing in Charlottetown

Health Canada's 2012 survey found 3.5% of 113 homes tested in the Prince Edward Island health region above the guideline. The larger 2024 Cross-Canada survey reports About 1 in 5 at or above the guideline (unweighted value for PEI.

The two surveys aren't directly comparable: the 2024 study pooled about 69,000 volunteer tests and more of them were taken in basements, which partly explains its higher numbers. Neither can tell you about a single house, because neighbouring homes can differ widely.

• Use a long-term test of at least three months, with most of it in the heating season, which gives the most conservative result.
• Place the detector in the lowest level you spend four or more hours a day in, away from drafts, and follow the kit's instructions.
• If the result is above 200 Bq/m³, Health Canada recommends fixing it within a year, sooner if it's much higher.

• Kits can be borrowed through the Provincial Library Service or ordered from LungNSPEI.
• For a professional measurement or mitigation, search the C-NRPP directory by your Charlottetown postal code; it lists certified measurement and mitigation professionals.

• PEI requires new homes to include a vapour barrier and a rough-in for a radon reduction system.
• The province points residents to the Canadian Lung Association's Lungs Matter program (up to $1,500) for mitigation funding.
• If your level is high, mitigation (usually a sub-slab depressurization fan system installed by a C-NRPP-certified professional) typically costs $2,000–$4,000.
