The Environmental Protection Agency strongly advocates regular radon inspections, stating “All homes should be tested regardless of geographic location.” To make a better-informed decision as to whether you should request a Radon test we have provided the EPA’s map of Radon Zones below. Inspect-It 1st St. Charles recommends radon testing in all areas, especially those in zones 1 and 2.
What is Radon?
Radon is a naturally occurring, invisible, odorless, tasteless gas that is dispersed in outdoor air, but which can reach harmful levels when trapped in buildings. Scientists have long been concerned about the health risk of radon, but never before has there been such overwhelming proof that exposure to elevated levels of radon causes lung cancer in humans.
The U.S. Environmental Protection Agency estimates that radon is responsible for more than 20,000 lung cancer deaths per year. Radon is the second leading cause of lung cancer in the U.S. after smoking and the leading cause of lung cancer among non-smokers.

|Zone 2 counties have a predicted average indoor radon screening level between 2 and 4 pCi/L (orange zones)|
|Zone 3 counties have a predicted average indoor radon screening level less than 2 pCi/L (yellow zones)|
