The biggest misconception about radon.

One of the most common misunderstandings I hear is that radon “doesn’t apply” to certain homes or locations.

Homeowners often believe:

• New construction homes are safe

• City homes (including Chicago and surrounding suburbs) don’t have radon

• Slab-on-grade homes are exempt

• A basement that isn’t used doesn’t matter

• Health or fitness can offset exposure risk

• If a neighbor has low radon, nearby homes must be low too

After thousands of tests, I can say confidently: none of these assumptions reliably predict radon levels.
