Questions about radon in Puerto Rico

Common questions

8 questions, answered from the figures above

Is radon a problem in Puerto Rico?

EPA's Map of Radon Zones places 0 of the 78 Puerto Rico municipios 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.

How do I get a radon test in Puerto Rico?

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.

Who does radon mitigation in Puerto Rico?

Which Puerto Rico counties have the highest radon?

EPA has not published a radon zone for Puerto Rico. 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 Puerto Rico are high?

CDC has published no statewide radon testing statistics for Puerto Rico, 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 Puerto Rico in?

Puerto Rico is in EPA Region 2: New Jersey, New York, Puerto Rico, U.S. Virgin Islands.

Do I need to test my home in Puerto Rico?

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 Puerto Rico?

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.
