Cabell County radon figures, compared

Calculated by Radon411

Cabell County's 145 reported tests over the 2008 to 2017 laboratory totals had a middle value of 2.0 pCi/L and a maximum of 22.8 pCi/L, and 16.6% reached 4 pCi/L. West Virginia as a whole (55 West Virginia counties, pooled) comes to 37.5%: 20.9 points higher than here.

Among its state's counties it ranks 25th of 27 West Virginia counties with 30 or more tests for the same period. Statewide for the same period, Morgan County reported the highest share (58.1%) and Grant County the lowest (9.8%).

Below the action level, 72 tests (49.7%) came in under 2 pCi/L, against 37.7% statewide, and 49 tests (33.8%) fell between 2 and 4, against 24.7% statewide. CDC's ten-year totals for Cabell County went from 132 tests (2005 to 2014) to 145 (2008 to 2017), the share going from 15.9% to 16.6%.

EPA's 1993 zone map puts Cabell County in Zone 2, a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.

Next door, the shares run from 23.1% in Putnam County to 30.3% in Lawrence County, OH.

CDC also counts 5 tests taken after mitigation in Cabell County for the same period: tests in homes where a fix was already in.

Cabell County, Cities and towns

Cities and towns in Cabell County

About 91,183 people live in Cabell County by the Census Bureau's estimate for July 1, 2025, 3,062 fewer than in 2020 (−3.2%). That works out to 324 people per square mile of land. Huntington, the largest place on its list (44,815 residents in all), extends beyond Cabell County, so no share of the total is worked out for it. Reported testing is thin here: 145 tests over 2008 to 2017, or 1.6 for every 1,000 residents (2025 estimate), where West Virginia as a whole comes to 5.7.

From Huntington to Milton, CDC publishes no figure by town: each reads Cabell County's.
