Radon is big problem for Iowans

David Osterberg, Clinical Professor, and Nancy Wyland, Research Support Specialist, Occupational and Environmental Health at the University of Iowa

Radon in our homes is a big problem for Iowans. It is the second-leading cause of lung cancer in our state, and unlike many environmental problems, you can do something about it. Everyone should test their home, whatever type it is. Testing is inexpensive, and winter is the best time for it, as doors and windows are closed.

Radon is a colorless, odorless, tasteless, radioactive gas produced from the decay of naturally occurring uranium in the soil. When this gas enters buildings in high concentrations and is breathed in, it can ultimately damage lung tissue, which can result in lung cancer. It doesn’t matter what type of foundation your home has or whether your home is new or old. Radon gas enters through openings between the foundation and the soil, including cracks in walls and floors, construction joints, gaps around service pipes, wires and sump pits.

Short-term tests can be purchased at most local hardware stores, or by contacting the Iowa Radon Hotline at 800-383-5992 or www.healthhouse.org.

Radon test kits provide results measured in picoCuries per liter. The U.S. Environmental Protection Agency recommends that homes and buildings with levels over 4.0 pCi/L have radon mitigation services performed to reduce exposure. Radon mitigation is a simple process that removes radon from under the foundation and vents it outside the home. A list of credentialed radon mitigation specialists for Iowa can be accessed at www.idph.state.ia.us/radon/Fix.aspx.

It is important to note that, as with all radioactive materials, there is no safe level of radon. Your family could be at risk for developing radon-induced lung cancer. So, test your home. It’s the right season, and the right thing to do.
