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. The 2024 Cross-Canada survey found about 27% of New Brunswick homes exceed the guideline, and testing is recommended across the province.

Radon levels vary from house to house and even neighbouring homes can have very different readings. A long-term test of at least 91 days during the heating season is the most reliable method.
