Radon Levels in Grady County, Georgia

Zone 3Lower predicted potential459 square miles · 5 bordering counties

What this means for you

  • Your area: EPA rates Grady County Zone 3, the lowest 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 radon tests reported to CDC for Grady County (2005 to 2014), 0.0% 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 2005 to 2014 laboratory totals, 0.0% of the radon tests reported to CDC for Grady County, Georgia came back at or above the EPA action level of 4 pCi/L, and the median result was 0.1 pCi/L. EPA's Map of Radon Zones places the county in Zone 3, lower predicted potential. Radon levels vary from home to home, so only a test measures the level in yours.

Predicted: EPA radon zone

EPA Zone 3: lower predicted potential

EPA predicts an average indoor of less than 2 pCi/L (less than 75 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 2005 to 2014, laboratory, counting radon tests reported to CDC, not homes. Grady 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 Georgia county’s own figure is in the Georgia county table.

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

Questions about radon in Grady County

Common questions8 questions, answered from the figures above

Are radon levels high in Grady County?

In 2014, 0.0% of the radon tests reported to CDC for Grady County, Georgia were at or above 4 pCi/L, and the median reported pre-mitigation result was 0.1 pCi/L. That is a share of reported tests, not of homes. EPA places Grady County in Zone 3, lower predicted potential, a predicted average indoor screening level less than 2 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 Georgia

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

Who does radon mitigation in Grady County?

No listed mitigator names Grady County as a service area yet; the Georgia directory lists 2 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 Georgia requires one.

How radon mitigation worksWhat mitigation costsMitigators in Georgia

What EPA radon zone is Grady County in?

EPA places Grady County, Georgia in Zone 3, which EPA describes as lower 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 Grady 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 Grady County?

Grady County borders 5 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 Grady County, Georgia in 2014. They describe tests other people carried out in other buildings, and none of them measures yours.

  • 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.

    How to test a home
  • If you are buying

    Ask for past results and any system's post-mitigation test, and test during the sale.
