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 2022: a percentage there is a share of radon tests reported to CDC for Petersburg Borough in 2022, 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 Petersburg Borough, 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 (1 for 2022). The median is the middle result of those tests, not of buildings.

Petersburg Borough'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 2022, counting radon tests reported to CDC, not homes. Petersburg Borough 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. Every Alaska county’s own figure is in the Alaska county table.

Measured: CDC tracking data. Measured data period: 2022.

What EPA radon zone is Petersburg Borough in?

Radon411 has no EPA Map of Radon Zones classification on file for Petersburg Borough, Alaska, so we are not going to state one. EPA's recommendation does not depend on the zone in any case: test every home.

Should I test my home in Petersburg Borough?

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.
