is EPA's lowest class, and its forecast for Pope 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.

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

CDC holds 13 reported tests for Pope County over the 2008 to 2017 laboratory totals, with a median of 2.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Pope County beside the counties around it is how this page reads it.

What these figures count

Only 13 tests were reported to CDC for Pope 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).

Pope County, Compared

Pope County radon figures, compared

Calculated by Radon411

CDC's largest figure for Pope County rests on 13 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 7.7 points and no rank or comparison is drawn from it. Results reached as high as 4.3 pCi/L, with a middle value of 2.7 pCi/L.

The nearest counties with a figure are Saline County (59 miles away) at 31.9%, Garland County (60 miles away) at 45.8% and Pulaski County (62 miles away) at 6.8%. 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 Pope 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.
