Is radon a problem in Puerto Rico?

Puerto Rico has 78 municipios on EPA's Map of Radon Zones: Zone 1, the highest predicted potential, for 0; Zone 2 for 0; Zone 3 for 0. An EPA radon zone predicts a whole county. It is not intended to determine whether any individual home should be tested: homes with elevated levels occur in all three zones, and EPA recommends testing every home regardless of zone.

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 Puerto Rico. 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.
