Is Bradford County, FL a radon risk area?

EPA's own radon map rates Bradford County zone 3 - low potential, predicting a county-wide average indoor level below 2 pCi/L. That puts Bradford County in the 17th percentile nationally for radon potential — higher than 17% of the counties EPA has rated.

Where Bradford County sits nationally

About 28,075 people live in Bradford County, Florida, spread over 293.966 square miles. Population density there runs about 96 people per square mile. Rank 508 by population within its EPA zone puts Bradford County at the 51st percentile among zone peers. Geologically, Bradford County is grouped into EPA Region 4 alongside 735 other counties that share its rock and soil setting.

Why the zone isn't the answer by itself

Bradford County's Zone 3 prediction undercuts the roughly 1.3 pCi/L most US homes average, nowhere near EPA's 4 pCi/L threshold for recommending mitigation. A Zone 3 label describes Bradford County's average, not any one basement or slab in it — testing is still the only way an individual homeowner actually finds out.

If Bradford County tests above the action level

Nothing about Bradford County'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.
