South Carolina Brochure: Building Radon Out: What you need to know to keep you and your family safe

by Margaret Henderson

Based on data collected from testing, almost every county in South Carolina has test results that are elevated (above 4 pCi/L, the recommended USEPA action level). A county map shows number of tests, average results and highest levels. http://www.scdhec.gov/HomeAndEnvironment/Docs/Radon/Radon_Map_2015.pdf

Because the potential exists for new homes to have high levels and need remediation, the South Carolina Department of Health and Environmental Control Radon Program encourages radon resistant new construction. The department has published a brochure with the basic information about radon and about Building Radon Out: What you need to know to keep you and your family safe. http://www.scdhec.gov/Library/CR-010089.pdf

The brochure discusses radon in South Carolina and why radon is dangerous. It explains about building radon out and the importance of testing after occupying the new home. A diagram is given with explanations about the “Features of Radon-Resistant Construction:”
• Gravel
• Soil-gas retarder
• Vent pipe “T
• Sealing
• Vent pipe
• Electrical junction box
• Roof flashing
• Vent pipe identification
