NASHVILLE, Tenn. (AP) -- State officials 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.
State officials recommend testing for radon during consistently cold weather.
The Tennessee Health Department and the state Department of Environment and Conservation will hold educational events from Oct. 16 to 22 in observance of Radon Awareness Week.
More information about radon can be found on the state Health Department's website. (link)
