Radon levels in Missouri vary significantly by region, with higher concentrations often found in the northern and central parts of the state due to uranium-rich bedrock. Testing is recommended for homes, especially in basements, as this odorless gas can accumulate and pose health risks over time. Many counties, like those in the Ozarks, show elevated levels, prompting local health departments to offer free or low-cost test kits.
