Radon Website: Website

Active Radon Program: Yes
Require License for Radon Professionals: No

South Carolina is the 40th most expansive state in terms of size and the 24th most populous in the entire US.

South Carolina does have an active radon program, dedicated to educating citizens about the risks associated with the deadly gas. You can find more information on Radon, testing and mitigation at the official page.

The radon levels in South Carolina are about average in many areas of the state. That being said, there is an increased risk for all homeowners, which is why we recommend testing exposure levels at least twice a year.

South Carolina Radon Levels

Map of South Carolina Radon Levels

Zone 1 (1): Potential for radon levels above 4 pCi/L according to EPA
Zone 2 (2): Potential for radon levels between 2 pCi/L and 4 pCi/L according to the EPA
Zone 3 (3): Lowest EPA level with expected radon levels at or below 2 pCi/L
Disclaimer: It is strongly recommended that all households, schools and office spaces test radon levels individually. The EPA Radon Zone data is not an indicator of individual test results, but a guideline for strategic planning. Toxic radon levels can be found in all counties, regardless of their zone rating. While we make efforts to keep this information up to date, it is derived from third­party sources which may not be accurate or reflect the most current statistics.

South Carolina Radon Statistics

South Carolina has 46 counties and 1 (2%) have been assigned Zone 1 counties by the EPA. Zone 1 counties have the highest potential to have homes test higher than 4 pCi/L. South Carolina's state radon zone average is 2.78, which is the average of all county zone ratings the EPA has assigned the state, ranking it 45 among all states.

South Carolina Radon Contractor License Information

Does South Carolina require contractors to be licensed? No.

What are the licensing requirements? There are no state mandated requirements to become a licensed radon contractor in South Carolina. Those looking for a radon certification can take qualified third party courses that are offered through the NRPP or AARST.

South Carolina Radon Real Estate Requirements

Does the state of South Carolina require radon testing for all real estate transactions? No

However both the state of South Carolina and the EPA recommend that a home or residence should be tested before a real estate transaction is carried out. Even though South Carolina does not require radon testing, we certainly recommend you have a test performed before you purchase a home. If you decide to perform a test after and find elevated levels, there is no reason to panic. South Carolina radon mitigation is not expensive compared to the dangers and a system can be implemented in a relatively short period of time.
