Radon Mitigation and Testing in Portland

Oregon’s rain, rich soils and unique geology result in elevated radon levels that are more common than people realize. This gas can be present in unexpected places, from properties on the hills of Forest Park to the flats of East Portland.

The good news is that testing is simple, and radon mitigation is possible with the right system. At SWAT Environmental, we’re here to ensure Portlanders can breathe easily, knowing their air is safe and their property is protected.

The Hidden Risk of Radon in Portland Homes and Businesses

Radon is an invisible, radioactive gas that forms naturally underground when uranium breaks down in soil and rocks. When it escapes from the soil and becomes trapped inside buildings, it can build up to reach dangerous levels over time.

Long-term exposure to radon is the second-leading cause of lung cancer in the U.S., and Oregon’s Department of Health identifies much of the Portland area as having moderate to high radon potential.

Testing results across Multnomah, Washington and Clackamas counties show that many Portland-area homes exceed the recommended action level of 4.0 pCi/L set by the Environmental Protection Agency (EPA). That’s why regular testing is key for homeowners and commercial properties.

Testing for Radon Is Your First Step to Safer Air in Portland, Oregon

Radon testing is the only way to know your property’s levels. You can choose from two main types of test kits, both available at local stores or online:

• Short-term kits deliver results in just a few days, making them perfect for quick assessments.
• Long-term kits monitor radon over at least 90 days, providing a more comprehensive view of year-round exposure.

Testing is especially important before real estate transactions, after major renovations, or as part of routine property care every one to two years. SWAT Environmental makes it easy by offering free radon test kits to Portland residents.

Radon Mitigation Tailored for Portland Properties

SWAT Environmental customizes every radon mitigation solution to fit the unique needs of Portland properties. We’ll start with a detailed assessment of your building’s structure and foundation to identify the most effective mitigation strategy. Our team will design and install a system to safely vent radon outside, often using advanced sub-slab depressurization.

Most systems are installed in a single day with minimal disruption. We also provide clear instructions for ongoing system care and support, so you can feel confident your property is protected for the long term.

What is radon?

Radon is a naturally occurring, radioactive gas that escapes when uranium in the soil decays. Radon becomes concentrated in a home, school or workplace as it seeps through cracks in the foundation or other natural openings in a structure.

At SWAT Environmental, we are dedicated to protecting families in and around Portland from radon exposure. Through our radon remediation process, our radon mitigation technicians have installed radon mitigation systems that reduce radon gas and make the air you breathe safer.

Any home in the Portland area is at risk for elevated radon levels. Radon testing is the only way to know if your home has harmful radon levels.

According to the Oregon Public Health Division‘s radon gas initiative:

• Portland is designated a radon gas Zone 2 by the EPA, having average radon levels of 3.0 pCi/L or higher.
• Radon gas causes over 20,000 radon-related death each year.
• The Surgeon General has warned that radon gas exposure is the second leading cause of lung cancer in the United States.
