Radon Testing


​​Radon is a gaseous radioactive element that occurs from the natural breakdown of uranium in the soil and rocks. It is colorless, odorless, and tasteless. Over time, it builds up in homes and is the second leading cause of lung cancer. 

O'Neil Home Inspections, LLC

​What We Provide

We use RadStar Continuous Radon Monitoring tests. These are short -term (approx. 2-4 days) and results are provided as soon as the testing is complete.

We do not do mitigation as to avoid conflicts of interest. 

O'Neil Home Inspections Can Help

​Radon is a risk to homeowners and it is recommended by the EPA that all homes in Oregon are tested. The EPA recommends that if the radon levels are at or above 4.0 pCi/L, then remediation should be done to lower the risk. Combined with smoking, the risk of cancer is even higher.

We are certified to perform these tests and provide you with the information you need to avoid the hazards that radon ​create.
