Learn the Risks of Radon during National Radon Action Month

January 16, 2019 


COLUMBIA, S.C. – To coincide with National Radon Action Month, the S.C. Department of Health and Environmental Control (DHEC) encourages South Carolinians to become familiar with the risks of radon when it’s present inside homes.


Radon is an invisible, odorless and tasteless gas that naturally exists in outdoor air, but it can be harmful to humans when too much of the gas is trapped inside buildings. High levels of radon exposure have been linked to more than 20,000 lung cancer deaths per year, according to the Environmental Protection Agency (EPA).


Radon comes from the natural breakdown of uranium in soil, rock and water, and it finds its way into homes through cracks and holes in the foundation, construction joints and plumbing fixtures. Any home can have a radon problem, and elevated levels of radon have been found in homes in almost every county of South Carolina.


“The only way to know if a home has high radon levels is to perform a test,” said Rhonda Thompson, DHEC’s Bureau of Air Quality Chief. “Two homes right next to each other can have different radon levels.”


DHEC has a limited number of free home radon kits that residents can use to test their homes. Test kits also may be purchased for about $15 from the National Radon Program.


Residents should closely follow the directions to receive accurate results. If the test kit indicates high levels of radon, the EPA recommends contacting a certified radon mitigation provider to review methods for preventing radon from entering a home.


South Carolina has nationally certified radon professionals who can measure radon levels and help fix homes with elevated radon levels,” said Leslie Coolidge, DHEC’s South Carolina Radon Program Coordinator. “We provide a list of these radon professionals on the DHEC website.”
