Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Norton city 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.

Measured: tests reported to CDC

Radon tests reported for Norton city, 2008 to 2017, laboratory

CDC holds 5 reported tests for Norton city over the 2008 to 2017 laboratory totals, with a median of 1.0 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Norton city beside the counties around it is how this page reads it.

What these figures count

Only 5 tests were reported to CDC for Norton city 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).

Norton city radon figures, compared

Calculated by Radon411

CDC's largest figure for Norton city rests on 6 tests over the 2006 to 2015 laboratory totals, 2 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 16.4 pCi/L, with a middle value of 1.3 pCi/L.

Wise County, the one bordering county with a figure over the 2006 to 2015 laboratory totals, reported 20.4% of its tests at or above 4 pCi/L. Farther out, Scott County (15 miles away) at 44.1%, Russell County (29 miles away) at 68.5% and Bristol city (34 miles away) at 40.2% have figures too. Pooled across 132 Virginia counties, 30.7% of reported tests reached that level; across every county in the country with a figure, 36.3%.

Statewide for the same period, Russell County reported the highest share (68.5%) and Norfolk city the lowest (5.3%). EPA's 1993 map puts Norton city in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 100% of the county's land moderate radon potential.
