The data

Morgan County, At a glance

Morgan County at a glance

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Morgan 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.

USGS geologic potential: Moderate across 100% of the county's area

Measured: tests reported to CDC

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

CDC holds 18 reported tests for Morgan County over the 2008 to 2017 laboratory totals, with a median of 1.2 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Morgan County beside the counties around it is how this page reads it.

What these figures count

Only 18 tests were reported to CDC for Morgan 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).

Morgan County, Compared

Morgan County radon figures, compared

Calculated by Radon411

CDC's largest figure for Morgan County rests on 18 tests over the 2008 to 2017 laboratory totals, 1 of them at or above 4 pCi/L, so each test moves its share by 5.6 points and no rank or comparison is drawn from it. Results reached as high as 4.4 pCi/L, with a middle value of 1.2 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 Rowan County the smallest, 18.9%. Farther out, Breathitt County (28 miles away) at 19.1%, Carter County (30 miles away) at 31.7% and Montgomery County (37 miles away) at 51.4% 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 Morgan 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.
