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 Ithaca, so every radon figure on this page belongs to a county and is labelled with it. Only a test tells you about one home.
Tompkins County has an EPA zone and its own CDC test figures, shown below. About 33,632 people live in Ithaca.

What it means
Ithaca, Questions
Questions about radon in Ithaca
What radon zone is Ithaca in?
EPA's Map of Radon Zones classifies counties, not cities. Tompkins County is in Zone 1 (highest predicted potential). A zone is a prediction for a whole county and never tells you the level in one home.
How many radon tests come back high in Ithaca's counties?
For 2023, the share of radon tests reported to CDC that were at or above 4 pCi/L was 38.9% in Tompkins County (18 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 Ithaca?
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.
The answers use the published figures of Tompkins County, the county Ithaca lies in.
