Upshur County, At a glance

Upshur County at a glance

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Upshur County is a county: EPA's forecast for it as a whole is an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³). It describes no single address, and homes above EPA's are found in every zone, this one included.

USGS geologic potential: Moderate across 100% of the county's area

Measured: tests reported to CDC

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

CDC holds 29 reported tests for Upshur County over the 2008 to 2017 laboratory totals, with a median of 2.6 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Upshur County beside the counties around it is how this page reads it.

What these figures count

Only 29 tests were reported to CDC for Upshur 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).

How to read these figures

Upshur County, Compared

Upshur County radon figures, compared

Calculated by Radon411

Upshur County's 30 reported tests over the 2005 to 2014 laboratory totals had a middle value of 1.8 pCi/L and a maximum of 16.4 pCi/L, and 16.7% reached 4 pCi/L. West Virginia as a whole (55 West Virginia counties, pooled) comes to 37.3%: 20.6 points higher than here.

The newest figure, over the 2008 to 2017 laboratory totals, counts only 29 tests (20.7% at or above 4 pCi/L), too few to compare, so this reading uses the 30-test figure.

Among its state's counties it ranks 21st of 26 West Virginia counties with 30 or more tests for the same period. Statewide for the same period, Morgan County reported the highest share (61.4%) and Grant County the lowest (7.1%).

Below the action level, 16 tests (53.3%) came in under 2 pCi/L, against 38.4% statewide, and 9 tests (30.0%) fell between 2 and 4, against 24.4% statewide. CDC's ten-year totals for Upshur County went from 30 tests (2005 to 2014) to 29 (2008 to 2017), the share going from 16.7% to 20.7%.

EPA's 1993 zone map puts Upshur 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 35.6% in Harrison County to 36.6% in Randolph County.
