NASHVILLE, Tenn. (AP) -- Two state agencies, the federal government and the American Lung Association are encouraging Tennesseans to test their homes for radon.
Radon is a naturally occurring gas that can enter homes through foundation cracks or openings. It's invisible and odorless and high concentrations can cause health problems including lung cancer.
The Environmental Protection Agency estimates that 70 percent of Tennesseans live in areas with high or moderate risk of radon.
The Tennessee Health Department and the state Department of Environment and Conservation are offering more information about radon and radon testing on their websites or by calling toll free to (800) 232-1139.
State officials recommend testing for radon during consistently cold weather.
