Certified radon testing in Portland, Oregon
Radon testing is the only way to know if your home has elevated radon levels. Radon is a colorless, odorless, radioactive gas that can lead to lung cancer — and it's present in homes throughout the Portland area. MTSO provides certified radon testing for residential and commercial properties in Portland, OR and Southwest Washington.
What to expect from MTSO's radon testing process
MTSO uses professionally calibrated radon testing equipment to measure radon concentrations in homes and businesses. Testing is non-invasive and typically requires 48 to 96 hours to complete, during which the monitoring device remains in the lowest occupiable level of the property.
Once testing is complete, a professional report is generated outlining the results and whether elevated radon levels were identified. As an independent testing company, MTSO does not perform radon mitigation and therefore has no financial interest in the outcome of the testing. If elevated levels are detected, referrals to qualified local mitigation contractors can be provided upon request.

Radon is odorless, tasteless, and invisible, and symptoms do not arise when a person has been exposed to it. In the air, radon is unstable and breaks down into other products. We inhale and exhale radon gas, but radon decay particles stay in the lungs. Over time, these particles can damage cells, which can mutate and cause lung cancer.
If radon is in your home at high concentration levels — brought in through the natural vacuum between the soil and the foundation of your home — it becomes a Class A carcinogen, a risk for lung cancer similar to cigarette smoking.
Radon is the second leading cause of lung cancer in the United States, following smoking. Even short-term exposure to high radon levels can be dangerous.
Radon is invisible and undetectable by the human senses. Testing is the only way to determine the radon levels in your home.
