Hansford County, TX: EPA's radon zone, explained

EPA places Hansford County in Zone 2 - Moderate Potential — a predicted county-wide average indoor radon level between 2 and 4 pCi/L, based on the geology, soil and aerial radioactivity data behind EPA's national map. Hansford County sits at the 36th percentile nationally for radon potential — above 36 of every 100 rated counties.

By population, Hansford County is the 943rd largest of every county sharing its EPA zone — the 9th percentile by population within that zone.

Zone vs. an actual test

Call it a middle case: above the 1.3 pCi/L most US homes average, below the 4 pCi/L line EPA uses to recommend mitigation — that's Hansford County's Zone 2 prediction. Middle-of-the-pack doesn't mean risk-free for any one Hansford County address — a moderate county average still leaves individual homes to test either side of it.

Testing and mitigation in Hansford County

For a Hansford County homeowner, the order is simple: test first, since a kit costs a small fraction of what mitigation would. Only if the result clears 4 pCi/L does a system — typically $800–$2,500, about $1,200 for a common install — become worth pricing out.
