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.

Generally, the air inside a home is lower pressure than the air outside, and combined with the warmer air rising inside, up to 20 percent of the air inside a house can come from the basement. When soil gas and air from fill enter the basement, it may include radon, which is then trapped inside house.

Radon gas continues to radioactively decay once inside the house, producing polonium, bismuth, and lead, which are also radioactive. As these radioactive elements transform, radioactive alpha and beta particles are released, and when inhaled and in contact with living lung tissue, can lead to cancer.

Any home can have a radon problem, the only way to know is to test. Some new homes are built with radon resistant construction techniques, it is still a good idea to plan a radon test to ensure the radon concentration is below the EPA action level. It is easy to add a professional radon test to your home inspections when buying a house.

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.

How does radon get into my home?

Radon is odorless, colorless, and tasteless; it is an inert noble gas. Radon is a naturally-occurring, carcinogenic, radioactive gas produced by the decay of radium in the soil. Radon gas exposure is the greatest single source of natural, ionizing, background radiation, only surpassed by medical radiation.
