Is Radon a Problem Where I Live in Idaho?


Radon is indeed a problem in the state of Idaho. The average level for radon in Idaho is 7.3 pCi/L which is alarmingly higher than the national average of 1.3 pCi/L. Radon is a severe problem in Idaho, more so than most every US state. Idaho has a worse radon problem than most of the US. 18 different counties in Idaho have been flagged by the EPA for having higher levels of radon than what is common. These counties include Benewah, Blaine, Boise, Boundary, Butte, Camas, Clark, Clearwater, Custer, Elmore, Fremont, Gooding, Idaho, Kootenai, Latah, Lemhi, Shoshone, and Valley.

If you live in any 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.

There are 21 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 just 5 counties that the EPA classified as Zone Three (radon levels between 0-1.9 pCi/L) range. This would suggest that radon is more of a minor issue in these counties, but that isn’t really the case. Tests have shown that radon is indeed quite the issue in most of these Zone Three counties. There are plenty of homes that have really high levels of radon sprinkled throughout the whole nation and 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.
