Radon
Radon is another hazardous material that has gained attention due to its presence in many homes across Iowa. It is a naturally occurring gas that originates from the decay of uranium in soil and rock. Since it is colorless and odorless, radon can accumulate in homes, particularly in basements, leading to elevated levels that increase the risk of lung cancer with prolonged exposure.
Radon is a natural radioactive gas that can cause cancer. You can’t see, smell or taste it, but radon may be in your home. Get more information about radon from the American Lung Association.
Iowa leads the nation in the percentage of homes over the EPA action level for radon (71.6%). Lung cancer caused by radon exposure results in 400 deaths annually in Iowa.
According to the Environmental Protection Agency (EPA), radon is the first leading cause of lung cancer in nonsmokers and the second leading cause of lung cancer in smokers.
High levels of radon can be found in any type of home, so it is important for everyone to test their home. You can order radon test kits by calling the Iowa Radon Hotline at 800-383-5992.
Iowa is designated by the EPA as an entirely Zone 1 state for radon, which means that at least 50% of the homes are above EPA's recommended action level.
Iowa has a law for radon testing and mitigation and Radon-Resistant New Construction Techniques (RRNC) in public schools, but there is currently no state law on RRNC regarding construction of new homes.
