Lexington city, At a glance

Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Lexington city in and predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county. That is one forecast for the whole county, not a reading of any address in it; homes above EPA's turn up in all three zones.

Calculated by Radon411

Lexington city's 32 reported tests over the 2008 to 2017 laboratory totals had a middle value of 1.6 pCi/L and a maximum of 6.1 pCi/L, and 18.8% reached 4 pCi/L. Virginia as a whole (131 Virginia counties, pooled) comes to 30.4%: 11.6 points higher than here.

Among its state's counties it ranks 72nd of 84 Virginia counties with 30 or more tests for the same period. Statewide for the same period, Russell County reported the highest share (67.3%) and Norfolk city the lowest (2.7%).

Below the action level, 18 tests (56.3%) came in under 2 pCi/L, against 44.7% statewide, and 8 tests (25.0%) fell between 2 and 4, against 24.9% statewide. CDC's ten-year totals for Lexington city went from 23 tests (2005 to 2014) to 32 (2008 to 2017), the share going from 26.1% to 18.8%.

EPA's 1993 zone map puts Lexington city in Zone 1, a predicted county average above 4 pCi/L. USGS geology rates 100% of the county's land high radon potential.

Rockbridge County, the one bordering county with a figure for the same period, reported 50.9%.
