Radon Zone Report
South Boston City is classified as EPA Radon Zone 3, the lowest risk category. The predicted average indoor radon screening level is below 2 pCi/L. However, elevated radon has been found in homes in all three zones, and the EPA recommends that all homes be tested.
Testing Recommendation
The EPA recommends testing all homes, even in Zone 3. While predicted levels are the lowest, elevated radon has been found in homes in every zone. Geology can vary significantly within a county, and individual home construction plays a major role. A simple test kit costs $15–$30.
Real Estate Considerations
While this area has the lowest predicted radon levels, it's still good practice to include radon testing in a home inspection, especially for homes with basements or slab-on-grade foundations. A basic test costs $15–$30 and provides peace of mind.
New Construction
While radon-resistant construction is not as critical in Zone 3, the incremental cost ($350–$500) during new construction is modest insurance. At minimum, consider installing a passive radon vent pipe during construction — it can easily be activated with a fan later if testing reveals elevated levels.
If Mitigation Is Needed
If your test results show 4 pCi/L or higher, contact a certified radon mitigation professional. The most common solution is a sub-slab depressurization system — a pipe and fan that pulls radon from beneath your foundation and vents it above your roof. These systems are highly effective, typically reducing radon by 80–99%. Installation usually takes less than a day. Retest your home after installation to confirm levels have dropped.
