Radon Levels in Muskingum County, Ohio

Zone 1Highest predicted potential673 square miles · 6 bordering counties

What this means for you

  • Your area: EPA rates Muskingum 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 391 radon tests reported to CDC for Muskingum County (2008 to 2017), 56.3% 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.

Over the 2008 to 2017 laboratory totals, 56.3% of the radon tests reported to CDC for Muskingum County, Ohio came back at or above the EPA action level of 4 pCi/L, and the median result was 4.9 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.

Each figure is that county’s own published CDC figure for 2008 to 2017, laboratory, counting radon tests reported to CDC, not homes. Muskingum 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 Ohio county’s own figure is in the Ohio county table.

CDC publishes this figure only for counties here, so there is no state or national number to compare Muskingum County, Ohio with.

Questions about radon in Muskingum County

Common questions8 questions, answered from the figures above

Are radon levels high in Muskingum County?

In 2017, 56.3% of the radon tests reported to CDC for Muskingum County, Ohio were at or above 4 pCi/L, and the median reported pre-mitigation result was 4.9 pCi/L. That is a share of reported tests, not of homes. EPA places Muskingum 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.

What a radon level meansRadon in Ohio

How do I get a radon test in Muskingum 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 Muskingum County as a service area yet. The Ohio radon program is the place to ask about certified testers and any test kit offer it runs.

Who does radon mitigation in Muskingum County?

No listed mitigator names Muskingum County as a service area yet; the Ohio directory lists 6 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 Ohio requires one.

How radon mitigation worksWhat mitigation costsMitigators in Ohio

What EPA radon zone is Muskingum County in?

EPA places Muskingum County, Ohio 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 Muskingum 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 Muskingum County?

Muskingum County borders 6 counties, derived from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county's report can be relevant.
