Radon levels in Greene County, New York
ModerateEPA Zone 1Predicted long-term basement average of 2.3 pCi/L (model estimate) across 33 ZIP codes - about 1.2× the US average of 1.8, about 1.7× the New York average of 1.4. Ranked #17 of 62 New York counties.
Test Greene County, NY - the EPA says "consider fixing" in this range
The predicted basement average here is 2.3 pCi/L, in the 2-4 pCi/L band where the EPA recommends considering mitigation. Plenty of individual homes in a moderate area test above 4. Start with a short-term test; if it comes back at 2 or higher, follow up with a long-term test or a continuous monitor.

Predicted (model estimate). The pCi/L figures on this page are long-term area averages from a peer-reviewed national model built on millions of real radon tests (2001-2021). They describe the typical home in this area - not your home, which can be several times higher or lower. The EPA radon zone is a separate, 1993 county-level classification. How the numbers work.

What this means for Greene
The typical Greene County home is predicted in the 2-4 pCi/L band. The EPA's guidance for this range is to consider fixing, because there is no known safe level and roughly one home in several in a moderate area will test above 4.
Note that the EPA classifies Greene County as Zone 1 while the newer model predicts 2.3 pCi/L. The zone map predates two decades of test data; where they disagree, we grade on the model but show both. County figures weight each ZIP by its 2010 Census population, so they describe where people live rather than empty land.
Comparable New York counties: Ulster County (2.2), Sullivan County (2.3), Yates County (2.2), Genesee County (2.3). The state's highest is Schuyler County at 2.8 pCi/L.

Mitigation is a routine job: a fan-driven pipe that vents soil gas from under the slab to above the roofline, typically $800-$2,500 installed (typical range; local quotes vary). Use certified professionals: EPA find-a-professional. Read the full mitigation guide.
Greene County radon questions
- Is radon high in Greene County, New York?
- Moderate. The model predicts a long-term basement average of 2.3 pCi/L in Greene County (about 1.2× the US average of 1.8 and about 1.7× the New York average of 1.4). That is in the 2-4 pCi/L range where the EPA recommends considering mitigation. Ranked 17 of 62 New York counties.
- Should I test for radon in Greene County?
- Yes, soon. With a predicted average of 2.3 pCi/L, many homes in Greene County will test above the 4 pCi/L action level. Use a short-term kit first; if it reads 2 or higher, confirm with a long-term test or continuous monitor before deciding on mitigation.
- What does EPA Radon Zone 1 mean for Greene County?
- Zone 1 - highest potential (predicted average > 4 pCi/L). The zone map dates from 1993 and classifies whole counties. The newer model's predicted average of 2.3 pCi/L does not line up with Zone 1, which is common - the EPA itself says high-radon homes exist in every zone. Neither replaces a test of your own home.
- How much does radon mitigation cost in Greene County?
- A standard active sub-slab depressurization system typically runs $800-$2,500 installed nationally; New York quotes vary with foundation type (slab, crawlspace, basement), home size and local labor. Get two or three bids from certified mitigators listed by your state radon program or the EPA's find-a-professional page.
