Pickett County, Compared
Pickett County radon figures, compared
Calculated by Radon411In Pickett County, about 5 in 10 reported tests over the 2008 to 2017 laboratory totals (20 of 43) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 10.8 points higher. Across 95 Tennessee counties pooled together, 33.3% of tests reached that level, so Pickett County runs 13.2 points above its state.
Of 6 neighbours with a figure, 2 reported a larger share at or above 4 pCi/L and 4 a smaller one; the spread is 2.6% (Scott County) to 60.9% (Wayne County, KY). By share, Pickett County is 12th of 80 Tennessee counties with 30 or more tests for the same period.
Half the tests came in under 3.5 pCi/L and half over it; the single highest reached 22.7 pCi/L. Below the action level, 15 tests (34.9%) came in under 2 pCi/L, against 42.4% statewide, and 8 tests (18.6%) fell between 2 and 4, against 24.3% statewide.
Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 46.5% share point the same way here. USGS geology rates 81% of the county's land moderate radon potential. CDC also counts 6 tests taken after mitigation in Pickett County for the same period: tests in homes where a fix was already in.
CDC's ten-year totals for Pickett County went from 38 tests (2005 to 2014) to 43 (2008 to 2017), the share going from 39.5% to 46.5%.
