CDC publishes this figure only for counties here, so there is no state or national number to compare Alachua County, Florida with.
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 2023: a percentage there is a share of radon tests reported to CDC for Alachua County in 2023, 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 Alachua 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 (659 for 2023). The median is the middle result of those tests, not of buildings. CDC also reports the number of buildings tested (624), a different count, so the two totals are not interchangeable.
Alachua County'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 2023, counting radon tests reported to CDC, not homes. Alachua County 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 2023: Bradford County, FL; Union County, FL; Gilchrist County, FL. Every Florida county’s own figure is in the Florida county table.

Alachua County, Questions
In 2023, 21.4% of the radon tests reported to CDC for Alachua County, Florida were at or above 4 pCi/L, and the median reported pre-mitigation result was 2.4 pCi/L. That is a share of reported tests, not of homes. EPA places Alachua 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.

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. No radon testing business listed on Radon411 has an address in Alachua County or names it as a service area yet.

No listed mitigator names Alachua County as a service area yet; the Florida directory lists 74 companies.

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

EPA places Alachua County, Florida 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.
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.
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.
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.
