Radon tests reported for Eastland County, 2008 to 2017, laboratory
CDC holds 2 reported tests for Eastland 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). Eastland County beside the counties around it is how this page reads it.
What these figures count
Only 2 tests were reported to CDC for Eastland 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).
Eastland County, Compared
Eastland County radon figures, compared
Calculated by Radon411CDC's largest figure for Eastland County rests on 3 tests over the 2007 to 2016 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 33.3 points and no rank or comparison is drawn from it. Results reached as high as 2.6 pCi/L, with a middle value of 0.1 pCi/L.
The nearest counties with a figure are Tarrant County (95 miles away) at 10.6%, McLennan County (110 miles away) at 17.1% and Denton County (117 miles away) at 7.2%. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%). EPA's 1993 map puts Eastland County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.

Eastland County, Geology
The ground under Eastland County
PredictedUSGS's geologic map puts all of Eastland County's mapped land in one class: low radon potential. The map puts 55.6% of Eastland County in the area it calls Central Texas and 44.4% in Central Texas/Gulf Coast Plain. USGS gives both a radon index of 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Central Texas | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 55.6% |
| Central Texas/Gulf Coast Plain | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 44.4% |

Eastland County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Eastland County's is. None of the 7 counties that border it has any moderate-potential ground either.
