Radon tests reported for Marion County, 2008 to 2017, laboratory
CDC holds 1 reported test for Marion County over the 2008 to 2017 laboratory totals, a result of 1.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Marion County beside the counties around it is how this page reads it.
What these figures count
Only 1 test was reported to CDC for Marion 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).
Marion County, Compared
Marion County radon figures, compared
Calculated by Radon411CDC's largest figure for Marion County rests on 2 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 50.0 points and no rank or comparison is drawn from it. Results reached as high as 1.0 pCi/L, with a middle value of 0.8 pCi/L.
The nearest counties with a figure are Muscogee County (23 miles away) at 2.1%, Harris County (35 miles away) at 10.9% and Houston County (51 miles away) at 8.2%. 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 Marion County in Zone 3, its lowest label: a predicted county average under 2 pCi/L. USGS geology rates 100% of the county's land low radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.
Marion County, Geology
The ground under Marion County
PredictedUSGS's geologic map puts all of Marion County's mapped land in one class: low radon potential. All of it lies in the area the map calls Coastal Plain, to which USGS gives a radon index of 8, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Cretaceous and Tertiary marine and coastal sediments including limestone, sandstone, sand, silt, and clay. Coastal plan sands containing glauconite may generate locally elevated radon. | Low | 8 | 100% |

Marion County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Marion County's is. Of the 7 counties that border it, 1 has more moderate-potential ground, Talbot County the most at 43.2%.
The map rates the ground, not the air in any home.
