Taylor County, Compared
Taylor County radon figures, compared
Calculated by Radon411More than half: 57.1% of the 91 radon tests reported to CDC for Taylor County over the 2008 to 2017 laboratory totals read at least 4 pCi/L. That places it 8th of 69 Kentucky counties with 30 or more tests for the same period. That is 13.4 points above the 43.7% pooled from 120 Kentucky counties.
The median result, 4.4 pCi/L, sits above EPA's 4 pCi/L action level, and the top reported result was 32.8 pCi/L. The rest split 19.8% under 2 pCi/L and 23.1% from 2 to 4 (Kentucky: 33.2% and 23.1%). Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 57.1% share point the same way here.
No bordering county with a figure for the same period reported a higher share; the closest is Marion County at 48.6%, the lowest Green County at 32.3%. Statewide for the same period, Meade County reported the highest share (68.4%) and Hopkins County the lowest (9.5%).
CDC's ten-year totals for Taylor County went from 95 tests (2005 to 2014) to 91 (2008 to 2017), the share going from 55.8% to 57.1%.

USGS gives the first a radon index of 12, in the high band (12 to 17), and the second 11, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Eastern Pennyroyal | Marine shale, sandstone and limestone. | High | 12 | 86.0% |
| Mississippian Plateau | Mississippian marine limestones, dolomites, marine sandstones, siltstones, and shales. | Moderate | 11 | 13.6% |
