Ohio Radon Potential

Know Your Zone. Test Your Home.

What does the EPA radon map tell you about Ohio? It shows county-level radon potential—a useful starting point for understanding the area where you live.

What the Map Tells You

The U.S. Environmental Protection Agency developed its radon zones map using measurements and information about geology, soil, and building foundations. It helps organizations direct resources and plan radon-resistant construction.

What It Cannot Tell You

A county’s color is not a measurement of your home. Elevated radon levels have been found in all three zones, and EPA recommends testing every home regardless of location.

Your home needs its own test. Use the map for regional context and a radon test to find out what is happening inside your property.

Understanding the Three Zones

Zone 1 — Red

Highest Radon Potential

Predicted average indoor screening level: greater than 4 pCi/L.

Zone 2 — Orange

Moderate Radon Potential

Predicted average indoor screening level: 2 to 4 pCi/L.

Zone 3 — Yellow

Low Radon Potential

Predicted average indoor screening level: less than 2 pCi/L.

These are county-level predictions, not individual property results. A Zone 3 designation does not mean a home is free of radon or cannot need mitigation.

Know what you're breathing

It starts underground.
It shouldn't stay in your air.

You can't see or smell radon. But this naturally occurring radioactive gas can enter homes and businesses, collect indoors, and increase the risk of lung cancer over time.

How radon gets inside

Detailed house cutaway showing common radon entry routes A cutaway shows a furnished living area above a basement, surrounded by soil and rock. Green arrows show radon entering through a foundation floor crack, a wall-floor joint, a gap around a service pipe, and an uncovered sump pit. Green haze illustrates potential indoor accumulation. Radon itself is invisible. LIVING SPACE BASEMENT 1 2 3 4 RADON RELEASED FROM SOIL & ROCK
  1. 1 Cracks in the foundation floor
  2. 2 Wall and floor joints
  3. 3 Gaps around service pipes
  4. 4 Sump holes and openings
Simplified illustration—not to scale. Green arrows and haze show the pathway; radon itself is invisible. Buildings without basements can also have elevated radon.

01 / What it is

Natural gas. Hidden risk.

Radon is a radioactive gas produced as naturally occurring elements break down in soil and rock. It has no color or smell. Outdoors it disperses; inside a building, it can accumulate.

02 / How it enters

Small openings. A way inside.

Radon moves from the ground through foundation cracks, construction joints, sump openings, and gaps around pipes. It can affect homes, apartments, offices, and other commercial buildings—including properties without basements. Groundwater supplies can also be a source.

03 / Why it matters

The damage happens over time.

As radon decays, it produces radioactive particles. When inhaled, those particles can damage cells lining the lungs. Long-term exposure increases lung cancer risk, and smoking raises that risk further. Testing reveals what your senses cannot.

~21,000

U.S. lung cancer deaths each year are attributed to radon by EPA estimates.

#2

Leading cause of lung cancer in the United States overall, after smoking.

#1

Leading cause of lung cancer among nonsmokers, according to the EPA.

You can't see it. You can test for it.
