The Louisville Metro Department of Public Health and Wellness is giving away free radon testing kits. Radon is the second leading cause of lung cancer in the U.S., behind smoking.
Radon doesn't have a smell, and can't be tasted, and it's a natural gas that is released when metals break down in rocks, soil and groundwater. About 40 percent of homes in Kentucky are estimated to have unsafe levels. And the only way to know if a home has unsafe levels is to test for radon.
Experts suggest opening windows and using ceiling fans to circulate indoor air to avoid exposure to radon. You can also seal cracks in floors with plaster and caulk to keep radon from leaking in.
