American Samoa Radon Map and Levels by County Equivalent

EPA's Map of Radon Zones places 0 of the 3 American Samoa county equivalents it classifies in Zone 1, the highest predicted potential, 0 in Zone 2 and 0 in Zone 3. An EPA radon zone describes predicted potential across a whole county. It is not intended to determine whether any individual home should be tested, and homes with elevated levels occur in all three zones. EPA recommends testing every home regardless of zone, and testing is the only way to know the radon level in a specific building.

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. Your state radon program is the place to ask about certified testers and any test kit offer.

Radon411 has no radon business listed for American Samoa yet. 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.

EPA has not published a radon zone for American Samoa. Radon411 will not rank counties on data it does not hold, and a zone is a prediction for an area rather than a measurement of any building.

CDC has published no statewide radon testing statistics for American Samoa, so we cannot give a figure. Where CDC does publish one, the percentage describes radon tests reported to CDC, not homes.

American Samoa is in EPA Region 9: Pacific Southwest.

Yes, wherever you live in the state. 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.

A statewide figure averages counties with very different geology and very different numbers of reported tests, so it hides more than it shows. The county report is the level at which the EPA zone, the geologic potential and the reported testing statistics are actually published, which is why the county table above links to every one of them.
