Questions about radon in Northern Mariana Islands

Common questions

8 questions, answered from the figures above

Is radon a problem in Northern Mariana Islands?

EPA's Map of Radon Zones places 0 of the 4 Northern Mariana Islands 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.

Which Northern Mariana Islands counties have the highest radon?

EPA has not published a radon zone for Northern Mariana Islands. 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.

What share of radon tests in Northern Mariana Islands are high?

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

Which EPA region is Northern Mariana Islands in?

Northern Mariana Islands is in EPA Region 9: Pacific Southwest.

Do I need to test my home in Northern Mariana Islands?

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.

Why does this page show coverage rather than one radon level for Northern Mariana Islands?

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.
