What EPA predicts hereScreening level, geology

What these figures count

Distribution of radon tests reported to CDC, not this house. People testing before a sale, or because they suspect a problem, are over-represented in any reported testing data.

The figures at the top are for 2018: a percentage there is a share of radon tests reported to CDC for Newport County in 2018, and a percentage in a view below is a share of the tests reported for the year or period it names. It is not a share of homes in Newport County, and it is not a random sample: it counts only the tests people chose to run and that were reported.

CDC works out the shares and the median over pre-mitigation tests, counting a test not marked as before or after mitigation as one of them (3 for 2018). The median is the middle result of those tests, not of buildings. CDC also reports the number of buildings tested (2), a different count, so the two totals are not interchangeable.

That is a share of reported tests, not of homes. EPA places Newport County in Zone 2, moderate predicted potential, a predicted average indoor screening level 2 to 4 pCi/L. Homes with elevated levels occur in all three zones, so the figures describe the area, not your house. Testing is the only way to know the radon level in a specific building.

How do I get a radon test in Newport County?

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.

Who does radon mitigation in Newport County?

No listed mitigator names Newport County as a service area yet; the Rhode Island directory lists 35 companies.

Your state radon program is the place to check whether Rhode Island requires one.

What EPA radon zone is Newport County in?

EPA places Newport County, Rhode Island in Zone 2, which EPA describes as moderate predicted potential for the area. A zone is a prediction for the whole county and never determines whether a particular home should be tested. EPA recommends testing every home regardless of zone.

Should I test my home in Newport County?

Yes. 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. How to test a home.

When is the best time of year to test?

EPA says short-term tests stay in the home from 2 to 90 days and that all radon tests should run a minimum of 48 hours; long-term tests stay more than 90 days. EPA's guides do not name a best season: they say radon levels tend to vary from day to day and season to season, so a long-term test is more likely than a short-term test to tell you the year-round average.

What does it cost to test?

EPA's Citizen's Guide calls testing easy and inexpensive, and EPA's Home Buyer's and Seller's Guide says passive short-term and long-term devices are generally inexpensive, while active devices may cost more. No national average price is published for this, so Radon411 does not give one. What testing costs.

Which counties border Newport County?

Newport County borders 1 county, derived from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county's report can be relevant.

Why bordering counties matter

One county shares a boundary with Newport County, computed from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county’s report can be worth reading alongside this one.
