Radon tests reported for Perry County, 2007 to 2016, laboratory
CDC holds 1 reported test for Perry County over the 2007 to 2016 laboratory totals, a result of 4.9 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Perry County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Perry County over 2007 to 2016 (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: 2007 to 2016, laboratory. Measured data period: 2005 to 2016 (every CDC figure on file).
Perry County, Compared
Perry County radon figures, compared
Calculated by Radon411CDC's largest figure for Perry County rests on 1 test over the 2007 to 2016 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 100.0 points and no rank or comparison is drawn from it. Results reached as high as 4.9 pCi/L, with a middle value of 4.9 pCi/L.
Of the counties bordering it, 3 have a figure over the 2007 to 2016 laboratory totals: Garland County reported the largest share at or above 4 pCi/L, 45.8%, and Pulaski County the smallest, 6.8%, with Saline County at 31.9% between. Farther out, Washington County (102 miles away) at 14.3% and Benton County (121 miles away) at 31.0% 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 Perry 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.
Perry County, Geology
The ground under Perry County
PredictedUSGS's geologic map puts all of Perry County's mapped land in one class: low radon potential. The map puts 86.9% of Perry County in the area it calls Athens Plateau/Fourche Mountains and 13.1% 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 |
|---|---|---|---|---|
| Athens Plateau/Fourche Mountains | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 86.9% |
| Arkansas Valley | Mississippian and Pennsylvanian sandstones and shales. | Low | 8 | 13.1% |
