Radon tests reported for Cumberland County, 2008 to 2017, laboratory
CDC holds 18 reported tests for Cumberland County over the 2008 to 2017 laboratory totals, with a median of 4.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Cumberland County beside the counties around it is how this page reads it.
What these figures count
Only 18 tests were reported to CDC for Cumberland 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).
Cumberland County, Compared
Cumberland County radon figures, compared
Calculated by Radon411CDC's largest figure for Cumberland County rests on 18 tests over the 2008 to 2017 laboratory totals, 10 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 17.5 pCi/L, with a middle value of 4.6 pCi/L.
Of the counties bordering it, 6 have a figure over the 2008 to 2017 laboratory totals: Monroe County reported the largest share at or above 4 pCi/L, 52.9%, and Russell County the smallest, 25.0%, with Clinton County at 47.5%, Metcalfe County at 45.5% and Adair County at 43.4% between. Farther out, Wayne County (31 miles away) at 60.9%, Barren County (33 miles away) at 51.6% and Green County (34 miles away) at 32.3% 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 Cumberland County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 86% of the county's land high radon potential.

The ground under Cumberland County
PredictedMost of the ground under Cumberland County is one class on USGS's geologic map: 86.4% of its land is high radon potential, with 13.6% moderate. The map puts 59.9% of Cumberland County in the area it calls Nashville Basin and 26.5% in Eastern Pennyroyal, with one smaller area beside them. USGS gives the first a radon index of 14 and the second 12, both in the high band (12 to 17).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Nashville Basin | Mississippian Limestone. | High | 14 | 59.9% |
| Eastern Pennyroyal | Marine shale, sandstone and limestone. | High | 12 | 26.5% |
| Mississippian Plateau | Mississippian marine limestones, dolomites, marine sandstones, siltstones, and shales. | Moderate | 11 | 13.3% |
