Radon Levels in Nye County, Nevada

EPA puts Nye County in Zone 2, its middle radon zone, and most reported tests there come back low, though 11.1% of 81 (2008 to 2017, laboratory totals) reached 4 pCi/L. Homes with elevated levels occur in all three zones, so only a test measures yours.

Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

Nye 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.

Nye County, Compared

Nye County radon figures, compared

Calculated by Radon411

Nye County reports fewer high tests than Nevada overall. 11.1% of its 81 tests over the 2008 to 2017 laboratory totals were at or above 4 pCi/L. That is 11.7 points below the 22.8% pooled from 16 Nevada counties.

Ordered from highest share down, it comes 10th of 11 Nevada counties with 30 or more tests for the same period. Nationally, every county with a figure for the same period pools to 35.7%; Nye County sits 24.6 points below it.

Next door, the shares run from 8.1% in Clark County to 39.1% in White Pine County, with Clark County below Nye County. Zone 2 on EPA's map (predicted average between 2 and 4 pCi/L) and a 11.1% share point the same way here.

Half the tests came in under 1.3 pCi/L and half over it; the single highest reached 7.1 pCi/L. The rest split 70.4% under 2 pCi/L and 18.5% from 2 to 4 (Nevada: 52.5% and 24.8%).

CDC's ten-year totals for Nye County went from 76 tests (2005 to 2014) to 81 (2008 to 2017), the share going from 11.8% to 11.1%.

What the Nevada Radon Education Program reports for the ZIP codes in Nye County

The Nevada Radon Education Program publishes its figures by ZIP code, not by county. These are the 9 ZIP codes that lie wholly or partly in Nye County, each with the state's own figures for it. Period: 1989-2015.

  • 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 Nye County

Predicted

Most of the ground under Nye County is one class on USGS's geologic map: 83.0% of its land is moderate radon potential, with 16.4% high and 0.6% low. The map puts 83.0% of Nye County in the area it calls Great Basin and 14.4% in Great Basin, with 3 smaller areas beside them. 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).
