Post Mitigation Radon Test Horizon

Why a Post-Mitigation Radon Test Is Non-Negotiable

Radon is a silent hazard. It has no smell, no color, and no taste, yet it remains the leading cause of lung cancer among non-smokers in the United States. In places like York and Adams County, Pennsylvania, where the geology is rich in uranium-bearing granite and shale, elevated indoor radon levels are common. Many homeowners take the right step by installing a mitigation system. But there is a critical follow-up step that far too many skip: the post-mitigation radon test.
