Radon tests reported for Crawford County, 2008 to 2017, laboratory
CDC holds 9 reported tests for Crawford County over the 2008 to 2017 laboratory totals, with a median of 0.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Crawford County beside the counties around it is how this page reads it.
What these figures count
Only 9 tests were reported to CDC for Crawford 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).
Crawford County, Compared
Crawford County radon figures, compared
Calculated by Radon411CDC's largest figure for Crawford County rests on 9 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 11.1 points and no rank or comparison is drawn from it. Results reached as high as 8.8 pCi/L, with a middle value of 0.7 pCi/L.
Washington County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 14.3% of its tests at or above 4 pCi/L. Farther out, Benton County (52 miles away) at 31.0%, Garland County (93 miles away) at 45.8% and Saline County (110 miles away) at 31.9% have figures too. Pooled across 60 Arkansas counties, 22.7% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Garland County reported the highest share (45.8%) and Pulaski County the lowest (6.8%). EPA's 1993 map puts Crawford 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.
Pooled shares: Radon411's sum of CDC's county counts for one period.

The ground under Crawford County
PredictedUSGS's geologic map puts all of Crawford County's mapped land in one class: low radon potential. The map puts 74.7% of Crawford County in the area it calls Boston Mountains and 25.3% in Arkansas Valley. USGS gives both a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
