Radon levels in St. Louis can be a concern because the area's geology, with its limestone and shale, allows this radioactive gas to seep into basements and lower floors. Testing is simple and cheap, but many homes go unchecked despite the known health risks like lung cancer over long exposure. It's worth checking your own home's level, especially if you're in a neighborhood with older houses or known underground rock formations.
