Last year Helen Caldicott, author of such books as Nuclear Power is Not the Answer and The New Nuclear Danger, joined us to discuss the dangers of nuclear power in the immediate wake of the Fukushima disaster. Now, one year after the disaster unfolded, we talk to Dr. Caldicott once again, this time to take about the legacy of Fukushima, what we now know actually took place in the days, weeks and months after the triple meltdowns, the likely long-term health effects of this disaster, and much more.

Paul Gunter is the Director of the Reactor Oversight Project at BeyondNuclear.org. As a long-time anti-nuclear activist, Gunter and Beyond Nuclear have been ringing the alarm bells about the GE Mark I Boiling Water Reactors in the United States–reactors with the exact same flawed design as the Fukushima Daiichi plant in Japan–for decades. Now, in the “Freeze our Fukushimas” campaign, Gunter and others are seeking to permanently suspend operations at all of the Mark I plants across the US.
