Predicted: EPA radon zone

EPA Zone 2: moderate predicted potential

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.

What EPA predicts hereScreening level, geology

EPA predicts an average indoor of 2 to 4 pCi/L (75 to 150 Bq/m³) across the county as a whole.

USGS geologic potential: Moderate across 54% of the county's area

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

What these figures count

Distribution of radon tests reported to CDC, not this house. People testing before a sale, or because they suspect a problem, are over-represented in any reported testing data.

The figures at the top are for 2008 to 2017 (laboratory totals): a percentage there is a share of radon tests reported to CDC for Livingston County over 2008 to 2017, laboratory, and a percentage in a view below is a share of the tests reported for the year or period it names. It is not a share of homes in Livingston County, and it is not a random sample: it counts only the tests people chose to run and that were reported.

CDC works out the shares and the median over pre-mitigation tests, counting a test not marked as before or after mitigation as one of them (4,885 for 2008 to 2017, laboratory). The median is the middle result of those tests, not of buildings. CDC also reports the number of buildings tested (3,306), a different count, so the two totals are not interchangeable.

Livingston County's own published CDC figures beside those of the counties that border it, for the same period.

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

Questions about radon in Livingston County

Common questions

8 questions, answered from the figures above

How do I get a radon test in Livingston 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 radon testing business listed on Radon411 has an address in Livingston County or names it as a service area yet. The Michigan radon program is the place to ask about certified testers and any test kit offer it runs.

Are radon levels high in Livingston County?

Over the 2008 to 2017 laboratory totals, 43.1% of the radon tests reported to CDC for Livingston County, Michigan were at or above 4 pCi/L, and the median reported pre-mitigation result was 3.4 pCi/L. That is a share of reported tests, not of homes. EPA places Livingston County in Zone 2, moderate predicted potential, a predicted average indoor screening level 2 to 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.

Who does radon mitigation in Livingston County?

No listed mitigator names Livingston County as a service area yet; the Michigan directory lists 69 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 Michigan requires one.

What EPA radon zone is Livingston County in?

EPA places Livingston County, Michigan in Zone 2, which EPA describes as moderate 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 Livingston 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 Livingston County?

Livingston 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.
