Dutchess County, At a glance

Dutchess County at a glance

Predicted: EPA radon zone

EPA Zone 1: highest predicted potential

EPA puts all of Dutchess County in and predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county. That is one forecast for the whole county, not a reading of any address in it; homes above EPA's turn up in all three zones.

What these figures count

Only 11 tests were reported to CDC for Dutchess County over 2023, 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: 2023. Measured data period: 2005 to 2023 (every CDC figure on file).

Dutchess County, Compared

Dutchess County radon figures, compared

Calculated by Radon411

In Dutchess County, about 4 in 10 reported tests over the 2008 to 2017 laboratory totals (871 of 2,133) were at or above EPA's action level. Against the national pool of 35.7%, the gap is 5.1 points higher. Across 62 New York counties pooled together, 24.5% of tests reached that level, so Dutchess County runs 16.3 points above its state.

The newest figure, in 2023, counts only 11 tests (45.5% at or above 4 pCi/L), too few to compare, so this reading uses the 2,133-test figure.

Of 7 neighbours with a figure, none reported a larger share at or above 4 pCi/L; the spread is 24.7% (Putnam County) to 39.8% (Columbia County). By share, Dutchess County is 7th of 61 New York counties with 30 or more tests for the same period.

Year by year, 2014 opened at 47.5% and 2022 closed at 8.3% (down 39.2 points), with 2018 the high at 50.0%. Half the tests came in under 3.0 pCi/L and half over it; the single highest reached 133.1 pCi/L. Below the action level, 783 tests (36.7%) came in under 2 pCi/L, against 51.7% statewide, and 479 tests (22.5%) fell between 2 and 4, against 23.7% statewide.

Zone 1 on EPA's map (predicted average above 4 pCi/L) and a 40.8% share point the same way here. USGS geology rates 100% of the county's land high radon potential. CDC also counts 154 tests taken after mitigation in Dutchess County for the same period: tests in homes where a fix was already in.

The busiest year on file was 2016, with 205 tests reported; the quietest, 2021, had 1.

Share of reported tests at or above 4 pCi/L by year, Dutchess County against New York2014 to 2022, years with 30 or more tests: Dutchess County 47.5% to 8.3%, the state's pooled share 22.4% in 2022.

Tests behind these figures

41.8 tests a year on average

  • Every figure is a five-year rolling average: the average result is the rolling average of each year's mean, and the test count is an average per year.
  • The data only include tests requested through the NYSDOH Radon Program, and therefore may not capture all radon tests performed in a county.
  • The data include both screening tests and post-mitigation tests, as it is not always possible to tell them apart.
  • Radon testing by homeowners is optional in New York, so the values may not be representative of every home in the county.
  • These figures describe tests reported to the New York State Department of Health in this area. They count a different set of tests than CDC's figures and are not a reading of any one home.
