South Carolina Presents Radon Data by County in State Map

by Margaret Henderson

The South Carolina Department of Health and Environmental Control (SCDHEC) used results from test kits analyzed by its laborary, from kits provided to residents who tested their homes. Test kit data through December 31, 2015, is presented on-line in a county map, giving average in-home radon concentrations.

For each county, the average result, highest level and number of tests are given. The highest level of 126.6 pCi/L was in Greenville County [Number of Test: 4654; Average Result: 4.2 pCi/L].

The map advises, “Just because the average for your county may not be as high as others, it is possible that you have elevated radon levels in your home. The only way to know for sure is to test. This map may differ from the EPA predicted risk Radon Zone Map since it is based on radon test kit results.”

For homeowners who have tested and need to mitigate, other helpful information is provided on the department’s website, including
• a checklist for radon mitigation to check the contractor’s work;
• a brochure on building radon out; and
• listings of certified measurement and mitigation specialists.
