From the video information: "Dr Helen Caldicott spoke to a standing room only crowd at the Faulkner Gallery in Santa Barbara on Friday evening March 23, 2012 on 'The Medical Implications of Fukushima, Nuclear Power and Nuclear Proliferation'". This is so worth the fourteen minutes and 43 seconds it takes to watch this, it's stunning. Link: http://en.wikipedia.org/wiki/Dr._Helen_Caldicott
