Radon is a radioactive gas found in many buildings, including schools, homes, and offices. The breakdown of uranium in soil, rocks, and water forms radon’s radioactive gas. Radon exposure is the second leading cause of lung cancer deaths in the United States, second only to smoking. The ideal time for radon testing in the home is during late fall and winter months.
The American Lung Association and the Pennsylvania Department of Environmental Protection are working together to provide radon test kits to Pennsylvania residents who have not yet tested their homes for dangerous radon gas.
