Did You Know?
RADON is the second leading cause of lung cancer after smoking.
RADON levels in your home can vary significantly from your neighbor's.
RADON can be found in homes with all types of construction, including slab-on-grade foundations, crawlspaces, and basements.
You can't see radon. And you can't smell it or taste it. But it may be a problem in your home. Radon is estimated to cause many thousands of deaths each year. That's because when you breathe air containing radon, you can get lung cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths.
Should I Test My Home for Radon?
The U.S. Surgeon General recommends that all homes be tested for radon. The U.S. Environmental Protection Agency (EPA) recommends taking a short-term test first that take from two to 90 days and allow for quick results. If your short-term results come back between 4 and 8pCi/L, the EPA suggests following up with a long-term test to confirm your results. Long-term tests run from 91 days to a year and can offer a more accurate measurement. If your short-term results come back over 8 pCi/L, perform another short-term test to confirm the results.
RECOMMENDATION: If your test results are 4 pCi/L or higher, the EPA recommends that you take immediate measure to lower radon levels in your home.
Testing Your Home for Radon
To determine if you have high levels of radon in your home, you have a couple options:
Where Can I Purchase Radon Detectors?

Please note that Portland Fire & Rescue does not have radon kits for purchase or donation.
What If the Test Reveals High Level of Radon?
The important thing is not to panic. Radon levels can fluctuate widely over time. Reducing radon levels in your home requires technical knowledge and skill, and typically involves hiring a radon mitigation contractor.
The most common approach to mitigating a radon problem is referred to as sub-slab depressurization or sub-slab suction. This technique draws radon-filled air from beneath the foundation through a pipe using a fan, and vents the radon outside. Sealing cracks and holes in the foundation makes this technique more effective.
