New Brunswick,
mapped to the bedrock.
Not every home faces the same risk. Radon levels follow the geology of the land itself, which is why they vary so much across New Brunswick. Find your region below to see what the bedrock beneath it means for your home.

Dive into the geology, risk profile, and towns served for every region of New Brunswick.
Moncton and Southeast
The Moncton region sits on sedimentary bedrock — mainly sandstone and shale — known to off-gas radon. Elevated levels have been documented across Southeastern New Brunswick.
View Region
Saint John and Fundy
The Fundy coast's sedimentary geology combined with older volcanic intrusions creates pockets of elevated radon, particularly in finished basements.

Fredericton and River Valley
The river valley's alluvial soils sit atop uranium-bearing bedrock. Oromocto, Nackawic, and Woodstock all warrant testing.
View Region
Charlotte County
Southwestern Charlotte County has some of the province's highest documented radon levels due to granitic intrusions near St. George and St. Stephen.

Bathurst and Acadian Peninsula
The Acadian Peninsula's metasedimentary geology produces moderate but variable readings. Coastal homes with sealed basements should still test.
