Radon is the second-largest cause of lung cancer, and though it represents a far smaller risk than cigarette smoking according to the National Cancer Institute, scientists estimate 15,000 to 22,000 lung cancer deaths in the U.S. annually are related to radon. According to the American Lung Association, all of Iowa has elevated radon levels, meaning Iowans have a high potential for elevated levels of radon gas statewide.

The Environmental Protection Agency recommends that homes be tested for radon about every three years, and when buying or selling a home. Radon can be a risk for those with or without a basement, and Iowa is known to be in a hot pocket of radon levels in the U.S. 

According to the EPA, radon reduction systems work. Some radon reduction systems can

reduce radon levels in your home by up to 99 percent. Radon mitigation systems pull the air from the soil and vent it outdoors. Most homes can be fixed for $1,500-$3,000. Your costs may vary depending on the size and design of your home and which radon reduction methods are needed. 

November is Lung Cancer Awareness Month, and some instances of lung cancer can be prevented if homeowners monitor their radon levels and take proper mitigation steps.
