On October 21, 2014, I was invited to be a speaker at the Eastern Washington American Nuclear Society Meeting. That talk was recorded and produced by volunteers at the section.
Perhaps as a result of jet lag or nervousness, I neglected to provide proper credit for borrowed slides. Though the words were mine, the slides I used were a remix of several presentations produced by others. Sources include Dr. Robert Hargraves excellent “Radiation is Safe Within Limits” and Dr. Bobby Scott’s 2008 presentation titled “Radiation activated natural protection against cancer and other diseases.”
Here is the video of the presentation.
