Jefferson County radon levels can be surprisingly high, especially in basements and lower floors. I live here and tested my home last year, finding levels above the EPA action limit. It's a colorless, odorless gas from uranium decay in the soil, and since our county sits on granite bedrock, it seeps in through cracks. Mitigation systems are common here, and local health departments offer affordable test kits.
