Is Radford city, VA a radon risk area?

Radford city is mapped as Zone 1 - Highest Potential by EPA — meaning the county-wide average indoor level is predicted above 4 pCi/L. Rank it against the rest of the country and Radford city lands in the 80th percentile for radon potential.

Radford city by the numbers

About 17,273 people live in Radford city, Virginia, spread over 9.676 square miles. Population density there runs about 1,785 people per square mile. Rank 612 by population within its EPA zone puts Radford city at the 43rd percentile among zone peers.

Why the zone isn't the answer by itself

Radford city's predicted average sits above EPA's own action level of 4 pCi/L — the concentration at which EPA recommends fixing a home — versus a national average around 1.3 pCi/L indoors and 0.4 pCi/L outdoors. Being in Zone 1 raises the odds Radford city homes test above the action level, but it does not mean any specific house does — EPA recommends every home be tested, in every zone, because the only way to know is to test.

Testing and mitigation in Radford city

Nothing about Radford city's EPA zone changes the mitigation number: $800–$2,500 nationally (around $1,200 typical), set by the house's foundation rather than the county it sits in — and only relevant once a test actually clears 4 pCi/L.
