What is it?
Radon is a radioactive noble gas. It comes from the natural decay of uranium that is found
in nearly all soils. It typically moves up through the ground to the air above and into your
home through cracks and other holes in the foundation.

Why test?
Radon is the second leading cause of lung cancer in the US, after smoking. The U.S.
Environmental Protecting Agency (EPA) and the Surgeon General strongly recommend
taking further action when the home’s radon test results are 4.0 pCi/l (Picocuries per liter of
air) or greater. Radon levels less than 4.0 pCi/l still pose some risk . The national average
indoor radon level is about 1.3 pCi/l while outdoor radon levels average 0.4 pCi/l. The
higher a home’s radon level, the greater the health risk to you and your family. Smokers
and former smokers are at especially high risk.
