Why Radon Levels Vary by Location

Geology, construction, and climate all play a role in your home’s radon risk.

🪨

Geology

Uranium-rich bedrock like granite, shale, and limestone produces higher radon. Regions near mountain ranges and glacial deposits are especially affected.

🏠

Construction

Homes with basements, crawl spaces, and foundation cracks allow more radon entry. Tight, energy-efficient construction can trap radon inside.

❄️

Climate

Cold climates with sealed homes see higher winter radon levels. High altitude and dry conditions can also concentrate radon gas indoors.
