Montgomery County, Compared
Montgomery County radon figures, compared
Calculated by Radon411No CDC figure names Montgomery County, in any year or ten-year total; over the 2007 to 2016 laboratory totals, the agency's counts reach 137 Georgia counties without it. Pooled across 137 Georgia counties, 23.9% of reported tests reached that level; across every county in the country with a figure, 35.8%.

Montgomery County, Geology
The ground under Montgomery County
PredictedUSGS's geologic map puts all of Montgomery 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% |

Montgomery County beside the ground around it
Across Georgia 26.5% of the land is rated moderate; none of Montgomery County's is. None of the 5 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.

Cities and towns in Montgomery County
The Census Bureau estimates 8,635 residents in Montgomery County for July 1, 2025, 70 more than in 2020 (+0.8%). That works out to 36 people per square mile of land. Vidalia, the largest place on its list (10,885 residents in all), extends beyond Montgomery County, so no share of the total is worked out for it. CDC publishes no radon test count for Montgomery County; across Georgia its counts for 2007 to 2016 come to 2.6 tests for every 1,000 residents (2025 estimate).
From Vidalia to Tarrytown, CDC publishes no figure by town: each reads Montgomery County's.
