About Radon in New Brunswick

Last updated: March 2026

New Brunswick has moderate to elevated radon risk, with the highest levels concentrated in areas underlain by uranium-bearing geological formations — particularly around Sussex, the Saint John River valley, and parts of the Fredericton region. The province's mix of older housing stock and varied geology means test results can differ significantly from one neighbourhood to the next. Health Canada surveys indicate a meaningful proportion of New Brunswick homes exceed the guideline, and testing is recommended across the province.

Frequently Asked Questions: Radon in New Brunswick

The Sussex area in Kings County, parts of the Saint John River valley, and some Fredericton-area communities sit over uranium-bearing geological formations and tend to record higher radon levels. However, every region of NB should be tested, as local geology varies.
New Brunswick follows Health Canada's national guideline of 200 Bq/m³. The New Brunswick Department of Health supports Health Canada's radon testing and mitigation recommendations.
Radon testing is not required by law in New Brunswick real estate transactions, though awareness is increasing. Some buyers in known higher-risk areas include radon testing in their inspection requests.
Radon enters through cracks in foundation walls and floor slabs, construction joints, gaps around pipes and posts, floor drains, and sump pits. In some areas, groundwater from drilled wells can also contribute radon to indoor air.
Health Canada recommends a minimum 91-day test during the heating season, placed in the lowest livable area of the home. This gives the most accurate picture of your average annual exposure.
Radon can dissolve in groundwater drawn from certain NB rock formations. If your home has a drilled well and your indoor radon tests high, a water test and point-of-entry aerator or carbon filter may be recommended alongside standard mitigation.
Use the city search above to find certified radon professionals serving Moncton, Fredericton, Saint John, and other New Brunswick communities.
