Radon is the second-leading cause of lung cancer and Iowans should test their homes during this National Radon Action Month. Environmental Protection Agency Administrator Andrew Wheeler states, “Nearly 21,000 people die each year from lung cancer caused by exposure to radon.” Iowa has a predicted average indoor radon screening at a high level. Radon is a radioactive gas that is tasteless and odorless and found in all kinds of soil and then seeps up. There are do-it-yourself radon test kits as well as qualified professionals to run tests. If a home presents high levels, there are mitigation systems that can be installed to safely remove the gas.
