Radon Levels in Taylor County, Texas

EPA puts Taylor County in Zone 3, its lowest radon zone, and only 28 radon tests from it are on file with CDC (2008 to 2017, laboratory totals). Homes with elevated levels occur in all three zones, so only a test measures yours.

EPA Zone 3: lower predicted potential

is EPA's lowest class, and its forecast for Taylor County as a whole is an average indoor of less than 2 pCi/L (less than 75 Bq/m³). A low zone clears no address in it: homes above EPA's turn up in all three zones.

Radon tests reported for Taylor County, 2008 to 2017, laboratory

CDC holds 28 reported tests for Taylor County over the 2008 to 2017 laboratory totals, with a median of 0.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Taylor County beside the counties around it is how this page reads it.

What these figures count

Only 28 tests were reported to CDC for Taylor 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).

Taylor County, Compared

Taylor County radon figures, compared

Calculated by Radon411

CDC's largest figure for Taylor County rests on 28 tests over the 2008 to 2017 laboratory totals, 2 of them at or above 4 pCi/L, so each test moves its share by 3.6 points and no rank or comparison is drawn from it. Results reached as high as 6.2 pCi/L, with a middle value of 0.8 pCi/L.

The nearest counties with a figure are Midland County (129 miles away) at 1.0%, Lubbock County (144 miles away) at 57.8% and Tarrant County (155 miles away) at 10.6%. 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 Taylor 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.

The ground under Taylor County

Predicted

USGS's geologic map puts all of Taylor County's mapped land in one class: low radon potential. All of it lies in the area the map calls Central Texas, to which USGS gives a radon index of 7, in the low band (5 to 8).

Testing a home in Taylor County

No CDC figure names Taylor County; the nearest county with one, Midland County (129 miles away), reported 1.0% of its tests at or above 4 pCi/L over the 2007 to 2016 laboratory totals, the only reading nearby until a test of this home. Zone 3 is the lowest label, yet homes at or above 4 pCi/L occur in every zone: a short-term kit (2 to 90 days) is the quick first check in Taylor County.

Taylor County, Cities and towns

Cities and towns in Taylor County

The Census Bureau estimates 150,077 residents in Taylor County for July 1, 2025, 6,593 more than in 2020 (+4.6%). That works out to 164 people per square mile of land. Abilene, the largest place on its list (131,588 residents in all), extends beyond Taylor County, so no share of the total is worked out for it. CDC's 28 reported tests for 2008 to 2017 work out to 0.2 per 1,000 residents (2025 estimate), close to Texas' 0.1.

From Abilene to Impact, CDC publishes no figure by town: each reads Taylor County's.
