The data

Wolfe County, At a glance

Wolfe County at a glance

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Wolfe County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

Measured: tests reported to CDC

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

CDC holds 4 reported tests for Wolfe County over the 2008 to 2017 laboratory totals, with a median of 0.1 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Wolfe County beside the counties around it is how this page reads it.

What these figures count

Only 4 tests were reported to CDC for Wolfe 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).

Wolfe County, Compared

Wolfe County radon figures, compared

Calculated by Radon411

CDC's largest figure for Wolfe County rests on 4 tests over the 2008 to 2017 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 25.0 points and no rank or comparison is drawn from it. Results reached as high as 0.9 pCi/L, with a middle value of 0.1 pCi/L.

Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Menifee County reported the largest share at or above 4 pCi/L, 22.0%, and Breathitt County the smallest, 19.1%. Farther out, Estill County (26 miles away) at 44.1%, Montgomery County (31 miles away) at 51.4% and Rowan County (32 miles away) at 18.9% have figures too. Pooled across 120 Kentucky counties, 43.7% of reported tests reached that level; across every county in the country with a figure, 35.7%.

Statewide for the same period, Meade County reported the highest share (68.4%) and Hopkins County the lowest (9.5%). EPA's 1993 map puts Wolfe County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
