Radon tests reported for Victoria County, 2008 to 2017, laboratory
CDC holds 5 reported tests for Victoria County over the 2008 to 2017 laboratory totals, with a median of 0.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Victoria County beside the counties around it is how this page reads it.
What these figures count
Only 5 tests were reported to CDC for Victoria 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).
Victoria County, Compared
Victoria County radon figures, compared
Calculated by Radon411CDC's largest figure for Victoria County rests on 6 tests over the 2006 to 2015 laboratory totals, 0 of them at or above 4 pCi/L, so each test moves its share by 16.7 points and no rank or comparison is drawn from it. Results reached as high as 2.6 pCi/L, with a middle value of 0.6 pCi/L.
The nearest counties with a figure are Nueces County (83 miles away) at 0.0%, Fort Bend County (88 miles away) at 3.4% and Brazoria County (96 miles away) at 6.3%. Pooled across 140 Texas counties, 10.4% of reported tests reached that level; across every county in the country with a figure, 35.8%.
Statewide for the same period, Randall County reported the highest share (71.4%) and Nueces County the lowest (0.0%). EPA's 1993 map puts Victoria 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.

Victoria County, Geology
The ground under Victoria County
PredictedUSGS's geologic map puts all of Victoria 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 7, in the low band (5 to 8).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Coastal Plain | Cretaceous through Quaternary marine sandstone, shale, chalk, limestone, siltstone, clay, and lignite. | Low | 7 | 100% |
Names, descriptions and indexes: U.S. Geological Survey, Geologic Radon Potential Map (2025). Shares: Radon411, from the map cut to the boundary.
Victoria County beside the ground around it
Across Texas 0.5% of the land is rated high; none of Victoria County's is. None of the 6 counties that border it has any moderate-potential ground either.
The map rates the ground, not the air in any home.
