January is National Radon Action Month.
The U.S. Environmental Protection Agency is encouraging Americans in all areas of country to test their homes for radon, a naturally occurring radioactive gas.
“Many people don’t realize that radon is the second cause of lung cancer after smoking,” said EPA Administrator Gina McCarthy.
Each year, about 21,000 Americans die from lung cancer caused by exposure to radon.
Testing is the only way to know if a home has elevated levels of radon, McCarthy said. The U.S. Surgeon General and EPA recommend taking action to reduce the radon level if it’s at or above 4 picocuries per Liter of air.
