Authority resource FAQ
Common Ohio Radon Resource Questions
Frequently Asked Questions
Where can I download the EPA radon guide for free?
The EPA "A Citizen's Guide to Radon" (EPA 402/K-12/002) is published free at epa.gov/radon. It is the foundational US consumer guide to indoor radon — covering health effects, testing methods, mitigation options, and the EPA action level. Spanish-language version also available at the same URL. The companion document, "Home Buyer's and Seller's Guide to Radon" (EPA 402/K-13/002), addresses real-estate-transaction-specific guidance.
How do I verify an Ohio radon contractor's NRPP certification?
Search the National Radon Proficiency Program directory at nrpp.info — enter the contractor's name or NRPP certification number to see active credentials, certification type (measurement vs mitigation), and expiration date. NRPP certifications expire every 2 years; verify the contractor's cert is current before scheduling work. For Ohio-specific dual-credential verification, also check the ODH Radon Division registration list.
How do I verify an Ohio radon contractor's ODH certification (Ohio Admin. Code Chapter 3701-69)?
Ohio requires both NRPP/NRSB national certification AND Ohio Department of Health (ODH) state registration for any radon mitigation work in Ohio. Call the ODH Radon Division at 614-466-0061 to verify a specific contractor's state registration, or request the current list of registered Ohio mitigators. Ohio Radon Experts verifies both credentials independently before routing leads to any partner contractor.
Where can I find Ohio school radon test results?
Ohio does not legally mandate school radon testing; ODH Bureau of Environmental Health and Radiation Protection encourages voluntary testing in EPA Zone 1 counties to test occupied ground-contact spaces every 5 years. Test results are filed with the Ohio Department of Education and ODH. Public-records requests for specific school results can be submitted through the Ohio Department of Education or directly through the school district. Aggregate Ohio school radon data is published in academic literature, notably by the The Ohio State University College of Public Health.
What Ohio universities or institutions conduct radon research?
The The Ohio State University College of Public Health conducts ongoing residential radon research (one of the largest US case-control studies linking residential radon to lung cancer outcomes). Ohio Geological Survey (Ohio Department of Natural Resources Division of Geological Survey) publishes on Ohio-specific radon geology (uranium-bearing Devonian Ohio Shale + Appalachian Plateau Devonian shale + Cambrian-Ordovician carbonate karst). Both maintain publication archives accessible through their respective university libraries.
Is residential radon testing covered by Ohio Medicaid?
No. Residential radon test kits and professional mitigation are NOT covered by Ohio Medicaid, Ohio Medicare, or any major commercial health insurance carrier in 2026. Radon is classified as an environmental hazard rather than a medical service. Self-pay test kits cost $15-30 (hardware store, ALA, or ODH); professional mitigation $800-$2,500. Some Energy Efficient Mortgage (EEM) products allow mitigation cost to be financed into a home loan.
Need to act on a radon test result?
Ohio Radon Experts routes Ohio homeowners to NRPP-certified + ODH-certified partner contractors. Free quote within 24 hours · $800-$2,500 typical install.
