Radon tests reported for White County, 2008 to 2017, laboratory
CDC holds 5 reported tests for White County over the 2008 to 2017 laboratory totals, with a median of 0.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). White County beside the counties around it is how this page reads it.
What these figures count
Only 5 tests were reported to CDC for White 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).
White County, Compared
White County radon figures, compared
Calculated by Radon411CDC's largest figure for White County rests on 7 tests over the 2006 to 2015 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 14.3 points and no rank or comparison is drawn from it. Results reached as high as 4.6 pCi/L, with a middle value of 1.7 pCi/L.
The nearest counties with a figure are Pulaski County (46 miles away) at 6.8%, Saline County (68 miles away) at 31.9% and Garland County (93 miles away) at 45.8%. 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 White 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.

White County, Geology
The ground under White County
PredictedUSGS's geologic map puts all of White County's mapped land in one class: low radon potential. The map puts 54.8% of White County in the area it calls Arkansas Valley and 39.3% in Mississippi Alluvial Plain, with one smaller area beside them. 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 |
|---|---|---|---|---|
| Arkansas Valley | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 54.8% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 39.3% |
| Athens Plateau/Fourche Mountains | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 5.9% |
