Radon is a natural form of radiation that can cause serious health problems and is often found in igneous rock and soil. An odorless, colorless radioactive gas; it forms from the radioactive decay of small amounts of uranium naturally present in rocks and soils.

Radon element from periodic table

Radon is estimated to be second only to tobacco smoking as the leading cause of lung cancer, responsible for over 20,000 estimated lung cancer deaths each year. Breathing air with a concentrated level of radon gas can result in an increased risk of developing lung cancer. Radon is second only to tobacco smoking as the leading cause of lung cancer. Radon is the primary cause of lung cancer among non-smokers in the United States, causing up to 14% of all lung cancers.

Two-thirds of our average annual dose from natural sources of radiation comes from radon, but we can take steps to reduce harmful levels of exposure. Radon can be found in workplaces, homes, and schools. Exposure from radon can occur through breathing outdoor air, in buildings and homes, and by eating or drinking.

EPA Map of Radon Zones in United States by state and county

Much of central Ohio is in Zone 1, which has the highest predicted indoor radon levels, over 4 pCi/L. The EPA action level for USA is 4 pCi/L. Many counties in Ohio have indoor radon concentrations that average much higher than the EPA action level, based on data from the Ohio Department of Health.

Any home can have a radon problem. You cannot predict radon levels inside a house based on state, local, or neighborhood radon measurements. Testing is the only way to know if you or your family are at risk from radon.

The EPA recommends that every home be tested for radon. Changes to your home such as additions, remodeling, or even a new roof or siding can change the level of radon inside your home. You can call 614-782-1705 or click the button below to schedule a radon test at your home.
