Information:

Radon data is published by county, not by city

Radon data is published by county, not by city. EPA assigns radon zones to counties, and CDC publishes radon test figures by county. Neither publishes a figure for Reno, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.

Washoe County has an EPA zone and its own CDC test figures, shown below. About 283,621 people live in Reno.

Questions about radon in Reno

What radon zone is Reno in?

EPA's Map of Radon Zones classifies counties, not cities. Washoe County is in Zone 2 (moderate predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.

For 2008 to 2017, laboratory, the share of radon tests reported to CDC that were at or above 4 pCi/L was 22.2% in Washoe County (5,046 tests). Each is that county's own figure, counting tests reported to CDC, not homes. Radon411 does not average or combine them into a figure for the city.

Should I test my home in Reno?

Yes. Testing is the only way to know the radon level in a specific building. EPA recommends fixing a home when the radon level is 4 pCi/L or higher. EPA recommends considering a fix when the level is between 2 and 4 pCi/L. How to test a home.
