Radon tests reported for Hancock County, 2008 to 2017, laboratory
CDC holds 6 reported tests for Hancock County over the 2008 to 2017 laboratory totals, with a median of 1.4 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Hancock County beside the counties around it is how this page reads it.
What these figures count
Only 6 tests were reported to CDC for Hancock County over 2008 to 2017 (laboratory totals), and tests are often run on homes being sold or already suspected of a problem: so few describe neither the county nor this house.
Measured: CDC tracking data. Figure above: 2008 to 2017, laboratory. Measured data period: 2005 to 2017 (every CDC figure on file).
Hancock County, Compared
Hancock County radon figures, compared
Calculated by Radon411CDC's largest figure for Hancock County rests on 6 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 16.7 points and no rank or comparison is drawn from it. Results reached as high as 4.1 pCi/L, with a middle value of 1.4 pCi/L.
Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Breckinridge County reported the largest share at or above 4 pCi/L, 31.3%, and Daviess County the smallest, 20.0%. Farther out, Meade County (32 miles away) at 68.4%, Grayson County (35 miles away) at 27.8% and Henderson County (44 miles away) at 24.1% have figures too. Pooled across 120 Kentucky counties, 43.7% of reported tests reached that level; across every county in the country with a figure, 35.7%.
Statewide for the same period, Meade County reported the highest share (68.4%) and Hopkins County the lowest (9.5%). EPA's 1993 map puts Hancock County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Hancock County, Geology
The ground under Hancock County
PredictedUSGS's geologic map puts all of Hancock County's mapped land in one class: moderate radon potential. The map puts 87.0% of Hancock County in the area it calls Western Coalfield and 11.5% in Mississippian Plateau, with 2 smaller areas beside them. USGS gives the first a radon index of 9 and the second 11, both in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Western Coalfield | Limestones, shale, siltstone, and coal beds. | Moderate | 9 | 87.0% |
| Mississippian Plateau | Mississippian marine limestones, dolomites, marine sandstones, siltstones, and shales. | Moderate | 11 | 11.5% |
| Crawford Upland/Mitchell Plain/Norman Upland | Unglaciated, underlain by karsted Mississippian carbonate rocks. | Moderate | 11 | 0.9% |
| Wabash Lowland | Loess, pre-Wisconsinan glacial deposits, Pennsylvanian shale, sandstone, and carbonate bedrock. | Moderate | 10 | 0.7% |
