Exposure to radon, an odorless, tasteless and invisible gas, is estimated to cause thousands of deaths each year and is the leading cause of lung cancer in nonsmokers.
This week is National Radon Awareness Week.
South Carolina’s Department of Health and Environmental Control experts said any home in one of South Carolina’s 46 counties may have a radon problem. High levels are not only possible in older homes or in certain areas of the state.
“There is a potential for a high reading in a low-risk area,” said Aimee Morrow, DHEC radon coordinator.
Radon comes from the breakdown of naturally occurring radium. It gets into your home through cracks and holes in the foundation, construction joints and plumbing fixtures.
It forms from the decay of naturally occurring uranium-238, which is found in soil and rock throughout the world. Exposure in homes mostly results from radon-contaminated gas rising from the soil, the American Cancer Society reports.
