Radon is a radioactive gas that you can't see, smell, or taste, but it's the second leading cause of lung cancer in the United States. Unfortunately, Idaho's geology makes it a hotspot for high radon levels.
Why Idaho?
The geology of the Gem State, particularly the uranium deposits in our soil and rock, naturally produces radon gas as it decays. When this gas rises, it gets trapped in our homes—especially in basements and crawlspaces during our long, sealed-up winters.
The Numbers Don't Lie
According to the Idaho Department of Health and Welfare, nearly 40% of homes tested in Idaho have elevated radon levels (above 4.0 pCi/L). In some counties like Ada and Blaine, that number is even higher.
Testing is Easy (and Essential)
A standard home inspection doesn't automatically include radon testing, but it's an affordable add-on (usually $150-$200).
- Passive Devices: Charcoal canisters left for 48 hours.
- Continuous Monitors: Digital devices that measure hourly fluctuations.
Can It Be Fixed?
Yes! A mitigation system typically costs between $1,200 and $2,500. If you're buying a home with high radon, this is a standard negotiation item. Don't walk away from a dream home because of radon—just ensure it's fixed.
