Radon tests reported for Montague County, 2008 to 2017, laboratory
CDC holds 16 reported tests for Montague County over the 2008 to 2017 laboratory totals, with a median of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Montague County beside the counties around it is how this page reads it.
What these figures count
Only 16 tests were reported to CDC for Montague 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).
Montague County, Compared
Montague County radon figures, compared
Calculated by Radon411CDC's largest figure for Montague County rests on 16 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 6.3 points and no rank or comparison is drawn from it. Results reached as high as 19.6 pCi/L, with a middle value of 0.1 pCi/L.
The nearest counties with a figure are Denton County (48 miles away) at 7.2%, Tarrant County (67 miles away) at 10.6% and Collin County (75 miles away) at 7.7%. 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 Montague 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.

The ground under Montague County
PredictedUSGS's geologic map puts all of Montague County's mapped land in one class: low radon potential. The map puts 54.7% of Montague County in the area it calls Central Texas/Gulf Coast Plain and 45.2% in Central Texas. 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/Gulf Coast Plain | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 54.7% |
| Central Texas | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 45.2% |
