EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Yell County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Measured: tests reported to CDC

Radon tests reported for Yell County, 2008 to 2017, laboratory

CDC holds 2 reported tests for Yell County over the 2008 to 2017 laboratory totals, with a median of 0.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Yell County beside the counties around it is how this page reads it.

What these figures count

Only 2 tests were reported to CDC for Yell 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: 2006 to 2017 (every CDC figure on file).

Yell County, Compared

Yell County radon figures, compared

Calculated by Radon411

CDC's largest figure for Yell County rests on 2 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 0.8 pCi/L, with a middle value of 0.5 pCi/L.

Garland County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 45.8% of its tests at or above 4 pCi/L. Farther out, Saline County (48 miles away) at 31.9%, Pulaski County (64 miles away) at 6.8% and Washington County (81 miles away) at 14.3% 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 Yell 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.
