Decades of research have shown that smoking is the leading cause of lung cancer in America, but non-smokers are not entirely free from risk either.

Scientists have found a link between radon exposure and lung cancer. This finding is of particular concern to Iowans because Iowa has the highest average radon concentration in the United States.

Radon is an odorless, tasteless and invisible radioactive gas. It can seep into your house through cracks and gaps in the foundation and get into the air you breathe.

See the EPA Radon Zones map to determine what radon zone your county falls into.

Radon test kits are available for $10 from the Iowa Department of Public Health (1-800-206-7818) and many major retail stores. If you find that your home contains unsafe levels of radon (more than 4 pCi/L) contact the Iowa Radon Line (1-800-383-5992) for a list of certified radon mitigation professionals in your area.
