Radon tests reported for Greene County, 2008 to 2017, laboratory
CDC holds 3 reported tests for Greene 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). Greene County beside the counties around it is how this page reads it.
What these figures count
Only 3 tests were reported to CDC for Greene 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).
Greene County, Compared
Greene County radon figures, compared
Calculated by Radon411CDC's largest figure for Greene County rests on 3 tests over the 2008 to 2017 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 1.4 pCi/L.
The nearest counties with a figure are Pulaski County (136 miles away) at 6.8%, Saline County (157 miles away) at 31.9% and Garland County (181 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 Greene County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 63% of the county's land low radon potential.

The ground under Greene County
PredictedUSGS's geologic map splits Greene County: 63.4% of its land is low radon potential and 36.6% moderate. The map puts 63.3% of Greene County in the area it calls Mississippi Alluvial Plain and 36.6% in Crowley's Ridge. USGS gives the first a radon index of 8, in the low band (5 to 8), and the second 9, in the moderate band (9 to 11).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 63.3% |
| Crowley's Ridge | Loess. | Moderate | 9 | 36.6% |
