Measured: tests reported to CDC
CDC holds 1 reported test for Crittenden County over the 2008 to 2017 laboratory totals, a result of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Crittenden County beside the counties around it is how this page reads it.
Only 1 test was reported to CDC for Crittenden 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).
Crittenden County, Compared
CDC's largest figure for Crittenden County rests on 1 test over the 2008 to 2017 laboratory totals, 0 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 0.1 pCi/L, with a middle value of 0.1 pCi/L.
Of the counties bordering it, 2 have a figure over the 2007 to 2016 laboratory totals: Shelby County, TN reported the largest share at or above 4 pCi/L, 7.0%, and Tipton County, TN the smallest, 4.5%. Farther out, Pulaski County (118 miles away) at 6.8%, Saline County (140 miles away) at 31.9% and Garland County (167 miles away) at 45.8% 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 Crittenden 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.

Crittenden County, Geology
USGS's geologic map puts all of Crittenden County's mapped land in one class: low radon potential. 99.4% of it lies in the area the map calls Mississippi Alluvial Plain, to which USGS gives 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 |
|---|---|---|---|---|
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 8 | 99.4% |
| Mississippi Alluvial Plain | Alluvial sand, silt, gravel, and clay. | Low | 7 | 0.6% |
