OK, I am taking the CERTI online course on Radon Measurement and Mediation and my head is about to explode. Physics of Radon! Yikes. Anyways I am trying to teach this old dog to learn again, but in the mean time I hope someone can help clarify what if anything is required of Home Inspectors in Oregon when it comes to testing for Radon? The question that I have not found on the state website stating that Oregon Home Inspectors must be Radon Certified to offer radon testing. Can anyone show me the light? I am going to complete my course at CERTI, but learning physics and the math behind it all is going to take this old dog a little more time and I would like to offer the testing asap. Thanks in advance.
