Why Residential Radon Testing is Essential
Early detection helps reduce long-term risk. The EPA has designated Ohio as Zone 1, its highest radon-potential category, and Franklin County, along with the rest of Central Ohio, falls squarely within it. Zone maps only indicate regional probability. They can’t tell you what’s happening inside a specific house in Columbus, Dublin, or any neighboring community.
Two homes built side by side, on the same soil, can produce very different readings depending on foundation design, ventilation, and how air moves through the structure. Testing is the standard the EPA recommends for every home in the region.

Radon Levels in Columbus &
Central Ohio
Franklin County and most of Central Ohio fall under the EPA’s Radon Zone 1 classification, meaning the predicted average indoor radon level is 4 pCi/L or higher, the same threshold the EPA sets as the action level for reducing exposure. Homes throughout Columbus, Dublin, Westerville, Hilliard, and the surrounding communities can test above this level no matter when they were built.
The reason ties back to the region’s underlying geology. Central Ohio sits on glacial till and limestone bedrock that lets radon gas move upward through soil and enter homes through cracks in foundations, sump pits, and other openings. Because levels vary house to house even on the same street, the only way to know where your home stands is a professional radon test.
FAQs
Frequently Asked Questions
Radon is a naturally occurring radioactive gas released as uranium in soil and rock breaks down. It enters homes through foundation cracks, sump pits, and other gaps below grade, and can't be detected by sight or smell.
Ohio is classified by the EPA as Zone 1, its highest radon-potential category, which is why testing is strongly recommended for homes throughout Columbus and Central Ohio.
The only reliable method is a test using calibrated equipment, either a short-term monitor or a continuous radon monitor.
The EPA recommends taking action to reduce radon levels at or above 4.0 pCi/L. Some homeowners choose to mitigate at lower levels as well, since no level of radon exposure is considered entirely risk-free.
Most standard radon tests take between 48 hours and a few days to complete. After testing, results are quickly analyzed and shared with you in a clear, easy-to-understand format.
Testing is recommended for homes that have never been tested, homes involved in a real estate transaction, homes that have undergone renovation or structural changes, and homes with an existing mitigation system that hasn't been verified recently.
No. Radon levels are determined primarily by geology and how a specific structure interacts with the soil beneath it, not by the age of the building. New construction and decades-old homes can both test above the action level.
If elevated radon levels are detected, a radon mitigation system can be installed to safely reduce levels. These systems are highly effective and can significantly improve indoor air quality.
While DIY kits are available, professional radon testing provides more accurate and reliable results using certified equipment. It also ensures proper placement, monitoring, and interpretation of the data.
It is recommended to test your home every 2–5 years, or sooner if you make structural changes or move into a new property.
Yes. We provide radon testing for homes throughout Columbus and the surrounding Central Ohio region. See our full list of service areas →
