EPA Zone 2: moderate predicted potential

Habersham County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

Habersham County radon figures, compared

Calculated by Radon411

In Habersham County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (48 of 128) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 1.8 points higher. Across 129 Georgia counties pooled together, 24.8% of tests reached that level, so Habersham County runs 12.7 points above its state.

Of 7 neighbours with a figure, 2 reported a larger share at or above 4 pCi/L and 5 a smaller one; the spread is 25.3% (Stephens County) to 42.6% (Oconee County, SC). By share, Habersham County is 13th of 57 Georgia counties with 30 or more tests for the same period.

Half the tests came in under 3.1 pCi/L and half over it; the single highest reached 29.9 pCi/L. Below the action level, 30 tests (23.4%) came in under 2 pCi/L, against 44.0% statewide, and 50 tests (39.1%) fell between 2 and 4, against 31.2% statewide.

Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 37.5% share point the same way here. USGS geology rates 100% of the county's land moderate radon potential. CDC also counts 9 tests taken after mitigation in Habersham County for the same period: tests in homes where a fix was already in.

CDC's ten-year totals for Habersham County went from 150 tests (2005 to 2014) to 128 (2008 to 2017), the share going from 28.7% to 37.5%.
