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 2020: a percentage there is a share of radon tests reported to CDC for Vermilion Parish in 2020, 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 Vermilion Parish, 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 2020). The median is the middle result of those tests, not of buildings. CDC also reports the number of buildings tested (1), a different count, so the two totals are not interchangeable.

Vermilion Parish's own published CDC figures beside those of the counties that border it, for the same period.

Each figure is that county’s own published CDC figure for 2020, counting radon tests reported to CDC, not homes. Vermilion Parish is this page. Nothing is averaged or combined across counties. The test count beside each county is CDC’s published number of pre-mitigation tests behind its figures. Figures from few tests can swing widely from year to year. No published CDC figure for 2020: Acadia Parish, LA; Iberia Parish, LA; Jefferson Davis Parish, LA; Cameron Parish, LA. Every Louisiana county’s own figure is in the Louisiana county table.

Who does radon mitigation in Vermilion Parish?

Radon411 has no radon business listed for Louisiana yet.

What EPA radon zone is Vermilion Parish in?

EPA places Vermilion Parish, Louisiana in Zone 3, which EPA describes as lower 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 Vermilion Parish?

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 Vermilion Parish?

Vermilion Parish borders 5 parishes, derived from Census county geometry. Radon potential follows geology rather than county lines, so a bordering county's report can be relevant.
