Radon Levels in Monroe County, Pennsylvania
What this means for you
- Your area: EPA rates Monroe County Zone 1, the highest of its three radon zones. That is a prediction for the whole county, and homes with elevated levels occur in all three zones.
- Local tests: Of 1,649 radon tests reported to CDC for Monroe County (2020), 30.7% were at or above 4 pCi/L, EPA's action level.
- Your home: The only way to know your home’s level is to test it.
pCi/L (picocuries per liter) is the unit radon is measured in. EPA recommends fixing a home at 4 pCi/L or above, its action level.
In 2020, 30.7% of the radon tests reported to CDC for Monroe County, Pennsylvania came back at or above the EPA action level of 4 pCi/L, and the median result was 2.1 pCi/L. EPA's Map of Radon Zones places the county in Zone 1, highest predicted potential. Radon levels vary from home to home, so only a test measures the level in yours.
Predicted: EPA radon zone
EPA Zone 1: highest predicted potential
EPA predicts an average indoor of greater than 4 pCi/L (greater than 150 Bq/m³) across the county as a whole.
This is a county-level geologic prediction. It is not a measurement of any address, and houses with elevated radon are found in all three zones.
USGS geologic potential: Moderate across 68% of the county's land area

Of 1,649 pre-mitigation tests reported to CDC, not homes in this area. CDC publishes the share in each band, not a count per band, so the per-band counts in the table are calculated by Radon411 and rounded to add up to the published total.
| Result band | Tests Calculated by Radon411 | Share Measured |
|---|---|---|
| Under 2 pCi/L | 798 | 48.4% |
| 2 to 4 pCi/L | 345 | 20.9% |
| 4 pCi/L and above | 506 | 30.7% |
Distribution of tested buildings, not this house. People testing before a sale, or because they suspect a problem, are over-represented in any reported testing data.

Monroe County in figures
What the published data says about Monroe County, in words. A zone and a share of tests describe an area, never the level in any one home.
Predicted
PredictedEPA places Monroe County in Zone 1, highest predicted potential, as it does 48 other counties of Pennsylvania's 67.
Of the 8 bordering counties, EPA places Carbon County, Lackawanna County, Luzerne County, Northampton County, Sussex County and Warren County in Zone 1 and Pike County and Wayne County in Zone 2.
Reported tests
MeasuredCDC has annual figures for Monroe County for 7 years, 2014 to 2020. In 2020, 30.7% of 1,649 reported tests were at or above 4 pCi/L.
Across those years the share ranged from 30.7% (2020) to 44.8% (2015). Few tests in a year can move it a long way.
Local record
Pennsylvania's radon program is the Radon Division, run by Department of Environmental Protection; its contacts are under Local resources.
The county's largest incorporated places are East Stroudsburg, Stroudsburg and Mount Pocono; the figures here cover them as part of the county.

What these figures count
Every percentage here is a share of radon tests reported to CDC for Monroe County in 2020. It is not a share of homes in Monroe County, and it is not a random sample: it counts only the tests people chose to run and that were reported.
The shares and the median are calculated from pre-mitigation tests (1,649 for 2020). CDC also reports the number of buildings tested (1,204), a different count, so the two totals are not interchangeable.

Each figure is that county’s own published CDC figure for 2020, counting radon tests reported to CDC, not homes. Monroe County is this page. Nothing is averaged or combined across counties. The test count beside each county is CDC’s published number of pre-mitigation tests behind its figures. Figures from few tests can swing widely from year to year. Every Pennsylvania county’s own figure is in the Pennsylvania county table.
CDC publishes this figure only for counties here, so there is no state or national number to compare Monroe County, Pennsylvania with.

Monroe County, Questions
Questions about radon in Monroe County
Common questions8 questions, answered from the figures above
Are radon levels high in Monroe County?
In 2020, 30.7% of the radon tests reported to CDC for Monroe County, Pennsylvania were at or above 4 pCi/L, and the median reported pre-mitigation result was 2.1 pCi/L. That is a share of reported tests, not of homes. EPA places Monroe County in Zone 1, highest predicted potential, a predicted average indoor screening level greater than 4 pCi/L. Homes with elevated levels occur in all three zones, so the figures describe the area, not your house. Testing is the only way to know the radon level in a specific building.
How do I get a radon test in Monroe County?
EPA says you can test your home yourself or hire a qualified radon test company, and that either approach takes only a small amount of time and effort. No certified tester listed on Radon411 names Monroe County as a service area yet. The Pennsylvania radon program is the place to ask about certified testers and any test kit offer it runs.
How to test a homeTest kits comparedFree and low-cost kits by statePennsylvania radon program
Who does radon mitigation in Monroe County?
No listed mitigator names Monroe County as a service area yet; the Pennsylvania directory lists 755 companies. EPA recommends having a qualified contractor fix a home with a radon problem, because lowering high radon levels takes technical knowledge and special skills, and some states require the work to be done by a licensed or certified professional. Your state radon program is the place to check whether Pennsylvania requires one.
How radon mitigation worksWhat mitigation costsMitigators in Pennsylvania
What EPA radon zone is Monroe County in?
EPA places Monroe County, Pennsylvania in Zone 1, which EPA describes as highest predicted potential for the area. A zone is a prediction for the whole county and never determines whether a particular home should be tested. EPA recommends testing every home regardless of zone.
Should I test my home in Monroe County?
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.
When is the best time of year to test?
EPA says short-term tests stay in the home from 2 to 90 days and that all radon tests should run a minimum of 48 hours; long-term tests stay more than 90 days. EPA's guides do not name a best season: they say radon levels tend to vary from day to day and season to season, so a long-term test is more likely than a short-term test to tell you the year-round average.
What does it cost to test?
EPA's Citizen's Guide calls testing easy and inexpensive, and EPA's Home Buyer's and Seller's Guide says passive short-term and long-term devices are generally inexpensive, while active devices may cost more. No national average price is published for this, so Radon411 does not give one. What testing costs.
Which counties border Monroe County?
Monroe County borders 8 counties, derived from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county's report can be relevant.
What these figures mean if you own, buy, sell or rent
The reported-test figures on this page describe Monroe County, Pennsylvania in 2020. They describe tests other people carried out in other buildings, and none of them measures yours.
- How to test a home
If you own your home
Test the lowest lived-in level; a short-term kit screens in days, a long-term kit reflects the year.
- Buying a house: radon guide
If you are buying
Ask for past results and any system's post-mitigation test, and test during the sale.
- Selling a house: radon guide
If you are selling
Testing before you list puts the timing in your hands; disclosure rules differ by state.
- Radon in rental homes
If you rent, or rent out a home
A tenant can test; a fix is the owner's to make, and duties differ by state.
