Radon tests reported for Lander County, 2008 to 2017, laboratory
CDC holds 17 reported tests for Lander County over the 2008 to 2017 laboratory totals, with a median of 2.8 pCi/L: too few to describe a county (Radon411 reads a share from 30 tests up). Lander County beside the counties around it is how this page reads it.
What these figures count
Only 17 tests were reported to CDC for Lander 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).
Lander County, Compared
Lander County radon figures, compared
Calculated by Radon411CDC's largest figure for Lander County rests on 17 tests over the 2008 to 2017 laboratory totals, 5 of them at or above 4 pCi/L, so each test moves its share by 5.9 points and no rank or comparison is drawn from it. Results reached as high as 8.9 pCi/L, with a middle value of 2.8 pCi/L.
Of the counties bordering it, 4 have a figure over the 2008 to 2017 laboratory totals: Elko County reported the largest share at or above 4 pCi/L, 40.3%, and Nye County the smallest, 11.1%, with Humboldt County at 32.3% and Churchill County at 12.4% between. Farther out, White Pine County (119 miles away) at 39.1%, Lyon County (131 miles away) at 30.4% and Storey County (137 miles away) at 17.6% have figures too. Pooled across 16 Nevada counties, 22.8% of reported tests reached that level; across every county in the country with a figure, 35.7%.
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 Lander County in Zone 1, the map's highest label: a predicted county average above 4 pCi/L. USGS geology rates 66% of the county's land moderate radon potential.
Pooled shares: Radon411's sum of CDC's county counts for one period.

What the Nevada Radon Education Program reports for the ZIP codes in Lander County
The Nevada Radon Education Program publishes its figures by ZIP code, not by county. These are the 2 ZIP codes that lie wholly or partly in Lander County, each with the state's own figures for it. Period: 1989-2015.
| ZIP code | What the state reports |
|---|---|
| 89310 | average 6.1 pCi/L |
| 89820 | average 2.2 pCi/L |
- 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.

Lander County, Geology
The ground under Lander County
PredictedUSGS's geologic map splits Lander County: 66.0% of its land is moderate radon potential and 34.0% high. The map puts 65.4% of Lander County in the area it calls Great Basin and 34.0% in Great Basin, with one smaller area 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).
| Area | The rock, in USGS's words | Potential | Radon index | Share of land |
|---|---|---|---|---|
| Great Basin | Sandstone, shale, limestone, mafic volcanic rocks. | Moderate | 11 | 65.4% |
| Great Basin | Tertiary silicic ash-flow tuffs and granitic rocks. | High | 12 | 34.0% |
| Owyhee Upland | Tertiary and Quaternary basalt, andesite, and rhyolite. | Moderate | 9 | 0.6% |

Lander County beside the ground around it
Lander County has more high-potential ground than Nevada as a whole: 34.0% of its land against 17.3%. Of the 6 counties that border it, none has as large a share of high-potential ground; Humboldt County comes nearest at 25.2%.
