The data

Elliott County, At a glance

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Elliott 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 Elliott County, 2008 to 2017, laboratory

CDC holds 5 reported tests for Elliott County over the 2008 to 2017 laboratory totals, with a median of 3.5 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Elliott County beside the counties around it is how this page reads it.

What these figures count

Only 5 tests were reported to CDC for Elliott 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).

Elliott County, Compared

Elliott County radon figures, compared

Calculated by Radon411

CDC's largest figure for Elliott County rests on 5 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 20.0 points and no rank or comparison is drawn from it. Results reached as high as 17.9 pCi/L, with a middle value of 3.5 pCi/L.

Of the counties bordering it, 2 have a figure over the 2008 to 2017 laboratory totals: Carter County reported the largest share at or above 4 pCi/L, 31.7%, and Rowan County the smallest, 18.9%. Farther out, Boyd County (28 miles away) at 17.9%, Menifee County (30 miles away) at 22.0% and Greenup County (31 miles away) at 12.5% 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 Elliott 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.

Elliott County, Geology

The ground under Elliott County

Predicted

USGS's geologic map puts all of Elliott County's mapped land in one class: moderate radon potential. The map puts 89.2% of Elliott County in the area it calls Cumberland Plateau and 10.8% in Central Allegheny Plateau. USGS gives the first a radon index of 9 and the second 10, both in the moderate band (9 to 11).
