Calculated by Radon411

Morgan County's 54 reported tests over the 2008 to 2017 laboratory totals had a middle value of 1.5 pCi/L and a maximum of 6.8 pCi/L, and 16.7% reached 4 pCi/L. Georgia as a whole (129 Georgia counties, pooled) comes to 24.8%: 8.1 points higher than here.

Among its state's counties it ranks 47th of 57 Georgia counties with 30 or more tests for the same period. Statewide for the same period, Barrow County reported the highest share (48.3%) and Richmond County the lowest (0.0%).

Below the action level, 33 tests (61.1%) came in under 2 pCi/L, against 44.0% statewide, and 12 tests (22.2%) fell between 2 and 4, against 31.2% statewide. CDC's ten-year totals for Morgan County went from 56 tests (2005 to 2014) to 54 (2008 to 2017), the share going from 8.9% to 16.7%.

EPA's 1993 zone map puts Morgan County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 92% of the county's land moderate radon potential.

Next door, the shares run from 17.6% in Greene County to 42.2% in Walton County.

The ground under Morgan County

Predicted

Most of the ground under Morgan County is one class on USGS's geologic map: 92.2% of its land is moderate radon potential, with 7.8% low. The map puts 92.2% of Morgan County in the area it calls Georgiabama Thrust Stack (South) and 7.8% 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).
