Is Radon a Problem Where I Live in California?





Radon is a noteworthy problem in the state of California. The average level for radon in California is 2.3 pCi/L which is higher than the national average of 1.3 pCi/L. Radon is a problem in California, just like it is in every US state. Just two counties in California have been flagged by the EPA for having higher levels of radon than what is common, but tests show that radon is a major issue in several additional counties. These counties are Santa Barbara and Ventura.

If you live in either of these counties, please run a radon test as soon as you can. You can do these yourself, or you can hire professionals. If you choose to run your own radon test, please visit this article to read about and pick up either the radon test kit that we recommend or our favorite radon detectors. Again, these two aren’t the only counties that have problems, but they are the two that the EPA made note of.

There are 30 counties that are in the EPA’s Zone Two (radon levels between 2-4 pCi/L) range, which is an area where radon is still a problem, but is not quite as bad as it is in the Zone One areas. It’s recommended that you test your home’s air for radon if you’re in a Zone Two area.

Finally, there are 26 counties that the EPA classified as Zone Three (radon levels between 0-1.9 pCi/L) range. Radon is more of a minor issue in these counties, but that does not necessarily mean that you’re out of the woods. There are plenty of counties that the EPA said are in Zone Three that tested out and have some really high average radon levels. There are plenty of homes that have really high levels of radon sprinkled throughout the whole nation. The only way to find out if your home has a radon issue is to test for it.

At the end of the day, counties that are marked as Zone One by the EPA have an increased risk of having a radon problem that’s really high, areas that are Zone Two have a higher risk of having a mid-level radon threat, and Zone Three counties have the lowest risk. Whatever zoning you’re in, it’s wisest to test for radon in your home. The zone designations serve as more of an idea on what you might be able to expect from your radon test results.

Here’s a county by county breakdown of California’s radon levels, as per the EPA and radon.com. If you’d like to see the nationwide data that we collected presented on tables, then you can do so on our article here.
