There are a number of concerns when buying or owning a home, but the state Department of Environmental Protection is hoping homeowners pay attention to a specific odorless and radioactive gas — radon.

Bob Lewis, the program manager for DEP’s Radon Division, finds that most people don’t really think of radon, even though Pennsylvania residents should worry about the levels in their home.

“Pennsylvania could be one of the worst states in the country,” Lewis said. “There’s a handful of states that show high levels of radon, and we’re up there. I think about 49 of the 67 counties in the state are EPA zoned 1 counties. It’s just a characteristic of our geography. It’s easy for gas to migrate through the ground.”

The federal Environmental Protection Agency splits the country into three zones of radon levels, with Zone 1 being the highest and Zone 3 having the lowest levels. Pennsylvania just happens to find itself in a Zone 1 hotspot, where levels of radon are most often above the acceptable limit. Not all of Pennsylvania is Zone 1.

Radon is a gas that rises from the soil. Radon levels are low enough outside that no one really has to worry about the risk being outside. However, radon can build up in enclosed spaces, such as homes, and increase the level of indoor radon to dangerous levels.

Radon is the second leading cause of lung cancer, and the leading cause in non-smokers. Radon is expected to be the cause of 20,000 lung cancer deaths every year, according to the DEP.

“Radon affects the lungs,” Lewis said. “Because it’s a gas, you breathe it in. The particles lodge on the lining tissue in the tracheal/bronchial part of the lung, and those particles are radioactive. It gives off radioactive emissions in the lung, which affects the DNA.”

There isn’t a set exposure level of radon that means all residents will get lung cancer. Those who smoke are much more likely to get lung cancer when being additionally exposed to radon, while it could be hit-and-miss for non-smokers who live in homes with high levels of radon, especially depending on how long a person has lived in that home.

“The best possible thing you can do is test your house,” Lewis said. “It’s so easy to do. You can get a test kit that costs $25 or $30 from a home center and test your house. We generally test in the basement, so you get the worst-case scenario number. People don’t realize they could test for it. I’ve been doing this for 25 years, and that seems to be the biggest misconception.”

    I see Lewis is a geologist and MD now. Sorry about that.

    Radon in air and water is an issue – your indoor air and water should be check and do not forget to check you well water quality. Make sure at a minimum to test for at least pH, conducitivity, nitrate, total coliform, and total dissolved solids.
