Esmeralda County, Compared

Esmeralda County radon figures, compared

Calculated by Radon411

Esmeralda County has no radon test figure of its own from CDC, whose counts over the 2008 to 2017 laboratory totals name 16 other Nevada counties and leave it out. Pooled across 16 Nevada counties, 22.8% of reported tests reached that level; across every county in the country with a figure, 35.7%.

Nye County, the one bordering county with a figure over the 2008 to 2017 laboratory totals, reported 11.1% of its tests at or above 4 pCi/L. Farther out, Lyon County (120 miles away) at 30.4%, Churchill County (130 miles away) at 12.4% and Douglas County (133 miles away) at 37.0% have figures too. Statewide for the same period, Carson City reported the highest share (40.6%) and Clark County the lowest (8.1%).

EPA's 1993 map puts Esmeralda County in Zone 2, its middle label: a predicted county average between 2 and 4 pCi/L. USGS geology rates 87% of the county's land moderate radon potential.

  • NBMG says the results are based on independently tested homes, not scientific sampling.
  • The service publishes an average for each ZIP code but no count of tests.
  • Site specific testing is the only way to determine local radon concentrations.
  • A ZIP code that crosses the county line is listed whole; its figures cover all of it.

The ground under Esmeralda County

Predicted

Most of the ground under Esmeralda County is one class on USGS's geologic map: 87.0% of its land is moderate radon potential, with 13.0% high. The map puts 86.9% of Esmeralda County in the area it calls Great Basin and 13.0% in Great Basin. USGS gives the first a radon index of 11, in the moderate band (9 to 11), and the second 12, in the high band (12 to 17).
