What This Means

Perquimans County, North Carolina is in EPA Radon Zone 3, the lowest risk category. Predicted average indoor radon levels are below 2.0 pCi/L. However, the EPA recommends testing all homes — even in low-risk areas, individual homes can have elevated radon due to local geology and construction factors.

What You Should Do

1
Testing is still recommended. Even in low-risk zones, individual homes can have elevated radon due to localized geology, foundation type, and construction factors.
2
If your result is below 2.0 pCi/L, no action is needed. Re-test every 2–5 years, or after major renovations that alter your foundation or ventilation.
3
If your result is 4.0 pCi/L or above, install a mitigation system — even in low-risk zones, some homes require active radon reduction.

Radon & Your Basement in Perquimans County

Perquimans County is in EPA Zone 3, the lowest risk category. However, basements in any zone can have elevated radon due to local soil conditions, foundation cracks, and construction factors.

Radon concentrations are typically highest in the lowest level of a home. However, radon does not stay confined to the basement — it migrates to upper floors through stairways, HVAC ducts, and gaps in flooring. Even if your basement is unfinished or rarely used, elevated radon there can affect the air quality on your main living floors. Always test on the lowest livable level.
