Radon Levels in U.S. Virgin Islands
What this means for you
- Your area: EPA has not published a radon zone for U.S. Virgin Islands.
- Local tests: CDC has published no radon test results for U.S. Virgin Islands.
- 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.
Predicted: EPA radon zone
No EPA zone on file for any county here
EPA has not published a radon zone for U.S. Virgin Islands.
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.
Predicted: EPA Map of Radon Zones
Measured: tests reported to CDC
CDC has published no radon test figures for U.S. Virgin Islands or its counties. Only a test tells you the level in a home.

Questions about radon in U.S. Virgin Islands
Common questions8 questions, answered from the figures above
Is radon a problem in U.S. Virgin Islands?
EPA's Map of Radon Zones places 0 of the 3 U.S. Virgin Islands counties 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 U.S. Virgin Islands?
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 U.S. Virgin Islands?

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.

Which U.S. Virgin Islands counties have the highest radon?
EPA has not published a radon zone for U.S. Virgin 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 U.S. Virgin Islands are high?
CDC has published no statewide radon testing statistics for U.S. Virgin 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 U.S. Virgin Islands in?
U.S. Virgin Islands is in EPA Region 2: New Jersey, New York, Puerto Rico, U.S. Virgin Islands.
Do I need to test my home in U.S. Virgin 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 U.S. Virgin 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.
What these figures mean if you own, buy, sell or rent
This page holds no radon measurement for U.S. Virgin Islands yet, so there is nothing here that could stand in for testing your building.
- How to test a home
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.
- Buying a house: radon guide
If you are buying
Ask for past results and any system's post-mitigation test, and test during the sale.
- Selling a house: radon guide
If you are selling
Testing before you list puts the timing in your hands; disclosure rules differ by state.
- Radon in rental homes
If you rent, or rent out a home
A tenant can test; a fix is the owner's to make, and duties differ by state.
How long a test has to run, under what conditions, and what EPA says a result means: the testing standard, in full.

Testing and mitigation products
Whatever the figures for U.S. Virgin Islands show, only a test tells you about one home.
Testing
- Short-term test kitsPassive detectors exposed for a few days under closed-building conditions, then analyzed by a lab.
- Long-term test kitsDetectors exposed for more than 90 days, for a closer picture of the annual average.
- Continuous monitorsPowered devices that log radon on a repeating cycle, often used for transaction tests.
- Digital detectorsConsumer devices that display a running radon reading without a lab.
- Water radon testsKits for radon dissolved in well water, analyzed by a lab.
Mitigation
- Mitigation fansThe inline fan that keeps a soil depressurization system running, sized by the installer.
- System indicatorsU-tube manometers and fan alarms that show whether a mitigation system is still working.
- Sealing materialsCrack, joint and sump sealing used alongside a mitigation system, not instead of one.
