What is radon and where does it come from?

 
 

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 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.

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.

Any home can have a radon problem, the only way to know is to test.

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.

Radon Information

What are radon levels in Franklin county, Ohio?

Central Ohio has high radon potential according to the EPA. Average radon levels recorded and submitted to the Ohio Department of Health range from 2 to 4 Pci/L (picoCuries per liter), shown in light blue in the graphic below, to ZIP Codes with averages over 10 Pci/L, shown in red in below.

Although there is no safe level of radon exposure, the EPA Action Level for indoor radon is 4.0 Pci/L. The first step to understanding the radon level inside your own home is to test–this is something you can include with your home inspections when buying a home, or anytime for your current home. Even if you already have a radon mitigation system, the EPA recommends that you test your home every two years–many changes to your home can change the amount of radon trapped inside the living area, including new windows, siding, or roof.

What is radon gas?


Radon is an odorless, colorless, tasteless, radioactive gas. Radon comes from the decay of radioactive uranium that can be found in small amounts in rocks and soil throughout nature. In areas with disturbed earth, and loose fill, like when a home is built, radon escapes from the soil.

Radon gas exposure is the number one cause of cancer for non-smokers, even greater than second-hand smoke. Most people are exposed to radon gas inside their own homes, and this is their greatest exposure to natural ionizing radiation.

Radon gas in Ohio

Central Ohio has relatively high natural concentrations of uranium from glacial deposits and shale, which during radioactive decay, produces radium and radon.

The EPA’s current radon action level is four picocuries of radon per liter of air (4 pCi/L). Most counties in central Ohio have high potential for radon, with predicted average indoor greater than the EPA action level. According to one study cited by Ohio Department of Natural Resources Department of Geological Survey, 38% of Ohio’s 88 counties had average indoor radon levels above 4.0 pCi/L, but Licking County’s average was above 8.0 pCi/L. Seven Ohio counties—Carroll, Fairfield, Franklin, Harrison, Knox, Pickaway, and Ross—had average indoor Radon concentrations between 6 and 8 pCi/L.
