Yes. Many counties across Central Ohio have moderate to high radon potential. The EPA classifies several Ohio counties in Zone 1 (the highest of three radon zones), and the Ohio Department of Health actively licenses radon professionals to ensure accurate testing and effective mitigation. Testing is the only way to determine levels in a specific home or building.
The Ohio Department of Health licenses radon professionals to ensure they meet state requirements for measurement and mitigation work. A Licensed Radon Specialist (RS) is qualified to conduct radon testing across residential and commercial settings. Shad has held license RS157 continuously since 2004, and the Protect Environmental Ohio entity holds Radon Contractor license RC 174.
Multi-family properties often have interconnected soil gas pathways and diverse foundation types, requiring layered mitigation design and performance testing to ensure consistency and occupant safety across units. NRPP multi-family certifications (which Shad holds) are the recognized credential for this work, and AARST/ANSI multi-family measurement standards apply.
