What Is Radon?
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. It seeps into homes through cracks in foundations, gaps around pipes, and other openings — accumulating to dangerous levels in enclosed spaces.
You can't see it, smell it, or taste it. The only way to know if your home has dangerous radon levels is through professional testing. The EPA recommends action when radon levels reach 4 pCi/L or higher.
Missouri is classified as a Zone 1 (highest risk) state by the EPA, meaning the average indoor radon levels are predicted to be above 4 pCi/L. Don't gamble with your family's health — get tested today.
