Radon In New York

Radon levels vary by geology, not by city limits, so two houses on the same street can read differently. The only way to know a home’s level is to test it. The map shows EPA radon zones across New York, which predict what is likely rather than what any individual house will measure.

Of the 62 counties in New York on this map, 34 are in EPA Zone 1, the highest of the three predicted levels.

Zone 1, highest: 34
Zone 2, moderate: 13
Zone 3, lowest: 15

Zones predict what is likely across a county. They say nothing about one house, and homes in every zone test high.

New York runs its own radon program, and it is worth a call before you spend anything: several states hand out discounted or free test kits, and the office can tell you what the rules are where you live.
