Louisville's health department is offering free radon testing kits.
Radon is a gas you can't smell, taste or see, but it's the second leading cause of lung cancer in the U.S, behind smoking. About 40 percent of Kentucky homes are estimated to have unsafe levels.
"Radon is a gas that you cannot smell, taste or see," a press release from the city's health department states. "It forms naturally when uranium, radium and thorium break down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in homes and other buildings. Radon can cause lung cancer through prolonged exposure."
The only way to know if you have radon in your home is to test for it.
