Radon is a colorless, odorless gas that causes up to 20,000 lung cancer deaths in the US each year. The only way to know if your home has dangerous levels of radon is to have it tested. You can buy radon test kits at local hardware stores and numerous places online including the Oregon State Health Authority.
It is important to understand that radon testing in Oregon is in its infancy with many zip codes having results from only a few tests. It is common for homes next to each other to radically different radon concentrations. While it is interesting to see what radon levels have been reported in your zip code, it is important to understand that radon concentrations can vary with different soil conditions and home constructions methods. The only way to know if your home is safe is to test.
Zip codes in the Eugene-Springfield area show moderate levels of radon with 5-10% of homes tested above the minimum level for remediation.
Many of us work hard to lead a healthy lifestyle, testing our homes for radon is an important part of the overall health picture!
