My inlaws smoked for many years. Neither got lung cancer. My father never smoked. He died of lung cancer.

I was looking at radon maps and my home county of Douglas County Kansas is a top radon county with many homes tested of 4 pCi/L or more. Cook County, where we live now is supposed to be averaging around 2 to 4. But there are homes in the low risk areas that measure quite badly and homes tested in the high risk areas that measure quite nicely.

Has anyone had any experience with testing and venting radon gas? I never have.
