About Radon
Radon is an odorless, colorless gas formed from the natural decay of Uranium.  Uranium is commonly found in rocks and soil.  As Radon gas is formed, it has a tendency to move along the path of least resistance, which is often upwards through the ground.  Radon most commonly enters a home through cracks in the foundation that come in contact with rocks or soil.  Radon easily becomes trapped in homes, especially when the home is well-sealed above ground, and can accumulate to dangerous levels.  Outdoors, radon is not harmful because the concentration is diluted in the air.

Radon is a radioactive gas and can lead to serious health problems if high levels go undetected in a home.  Researchers have shown evidence of a link between radon in the indoor environment and lung cancer.  It is estimated that radon causes 21,000 lung cancer deaths per year in the United States.  Research also suggests that smokers have a significantly higher risk of developing lung cancer from radon.

The amount of radon formed depends on soil chemistry, which can vary greatly in a small geographic area.  This is often why one home may have high levels of radon, while a neighboring home has acceptable levels.  Since there are no immediate symptoms that may alert you to the presence of radon in your home, testing is the only way to accurately determine a home’s radon level.  A quality do-it-yourself radon test kit can be purchased at a home improvement store; however, if you are buying or selling a home, a qualified radon professional should be contacted. 

Radon is measured in pico-Curries per Liter (pCi/L).  Levels above 4 pCi/L are considered elevated.  If a home test kit reveals a level above 4pCi/L, a radon professional should also be contacted as they have more sophisticated test equipment that may validate your do-it-yourself results.  A professional can also help determine the proper course of action to correct the problem, which usually involves installation of a radon mitigation system.  Depending on your home, radon levels, and soil characteristics, there are multiple types of radon mitigation systems available.  Most systems either prevent radon from entering a home or reduce radon levels after it has entered a home.

Please note that our department does not have licensed radon inspectors on staff. If you are interested in determining the radon levels in your home, please purchase a do-it-yourself radon test kit, or search for licensed radon professionals in the phone book or on the Ohio Department of Health (ODH) website at http://www.odh.ohio.gov/odhPrograms/rp/radlic/radon.aspx.
