Radon Levels in Arnold, MO

Radon is a naturally occurring radioactive gas that can pose significant health risks when it accumulates indoors. Jefferson County, where Arnold is located, is classified by the Environmental Protection Agency (EPA) as a Radon Zone 2 area, meaning predicted indoor radon levels typically range between 2 and 4 picocuries per liter (pCi/L). While these levels are considered moderate, the EPA strongly recommends mitigation for levels at or above 4 pCi/L and suggests considering mitigation for levels between 2 and 4 pCi/L.

In Missouri, an estimated 1 in 5 homes may have radon levels exceeding the EPA’s recommended limit, making radon testing an essential step for homeowners in Arnold. Ensuring that your home is tested and, if necessary, equipped with a mitigation system can protect your family from long-term health risks associated with radon exposure.
