Upson County, At a glance

Upson County at a glance

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Upson 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 Upson County, 2008 to 2017, laboratory

CDC holds 15 reported tests for Upson County over the 2008 to 2017 laboratory totals, with a median of 0.7 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Upson County beside the counties around it is how this page reads it.

What these figures count

Only 15 tests were reported to CDC for Upson 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).

Upson County radon figures, compared

Calculated by Radon411

CDC's largest figure for Upson County rests on 15 tests over the 2008 to 2017 laboratory totals, 3 of them at or above 4 pCi/L, so each test moves its share by 6.7 points and no rank or comparison is drawn from it. Results reached as high as 11.2 pCi/L, with a middle value of 0.7 pCi/L.

Monroe County, the one bordering county with a figure over the 2007 to 2016 laboratory totals, reported 23.8% of its tests at or above 4 pCi/L. Farther out, Spalding County (26 miles away) at 33.0%, Bibb County (35 miles away) at 0.0% and Harris County (37 miles away) at 10.9% have figures too. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.

Statewide for the same period, Barrow County reported the highest share (51.0%) and Dougherty County the lowest (0.0%). EPA's 1993 map puts Upson County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 84% of the county's land moderate radon potential.

Upson County, Geology

The ground under Upson County

Predicted

Most of the ground under Upson County is one class on USGS's geologic map: 84.1% of its land is moderate radon potential, with 15.9% low. The map puts 84.1% of Upson County in the area it calls Georgiabama Thrust Stack (South) and 15.9% in Little River Thrust Stack. USGS gives the first a radon index of 9, in the moderate band (9 to 11), and the second 7, in the low band (5 to 8).
