Clinton County, Compared

Clinton County radon figures, compared

Calculated by Radon411

In Clinton County, about 5 in 10 reported tests over the 2008 to 2017 laboratory totals (19 of 40) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 11.8 points higher. Across 120 Kentucky counties pooled together, 43.7% of tests reached that level, so Clinton County runs 3.8 points above its state.

Of 4 neighbours with a figure, 1 reported a larger share at or above 4 pCi/L and 3 a smaller one; the spread is 25.0% (Russell County) to 60.9% (Wayne County). By share, Clinton County is 19th of 69 Kentucky 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 36.2 pCi/L. Below the action level, 10 tests (25.0%) came in under 2 pCi/L, against 33.2% statewide, and 11 tests (27.5%) fell between 2 and 4, against 23.1% statewide.

Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 47.5% share point the same way here. USGS geology rates 83% of the county's land moderate radon potential.

CDC's ten-year totals for Clinton County went from 24 tests (2005 to 2014) to 40 (2008 to 2017), the share going from 58.3% to 47.5%.
