Peer Reviewed Study Shows 14,000 U.S. Deaths from Fukushima

"... To unpack a little more, the authors take mortality figures from the Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Reports. I talk a little about these reports in my original piece. Suffice it to say that they are an incomplete record of deaths in the U.S. (as the authors acknowledge). The authors draw a hard line at the week of March 20, 2011, the 12th week of the year. They sum up all deaths around the country for both the 14 weeks preceding and the 14 weeks following March 20, 2011. They do the same for 2010. They find the CDC reports include 4.46 percent more dead people in the 14 weeks after March 20, 2011, than the reports did in the 14 weeks after March 20, 2010. The 14 weeks preceding March 20, 2011 (presumably before the radiation plume arrived and spread across the land) include only 2.34 percent more dead people than the 14 weeks preceding March 20, 2010. Since the CDC only reports on about 23.5 percent of all deaths, the authors claim, they helpfully multiply the supposed “excess” by 1/0.235 to arrive at the final number of 13,893 deaths.

No attempt is made at providing systematic error estimates, or error estimates of any kind. No attempt is made to catalog any biases that may have crept into the analysis, though a cursory look finds biases a-plenty (the authors are anti-nuclear activists unaffiliated with any research institution). The analysis assumes that the plume arrived on U.S. shores, spread everywhere, instantly, and started killing people immediately. It assumes that the “excess” deaths after March 20 are a real signal, not just a statistical aberration, and that every one of them is due to Fukushima radiation.

The publication of such sloppy, agenda-driven work is a shame. Certainly radiation from Fukushima is dangerous, and could very well lead to negative health effects—even across the Pacific. The world needs to have a serious discussion about what role nuclear power should play in a power-hungry post-Fukushima world. But serious, informed, fact-based debate is a difficult enough goal to achieve without having to shout above noise like this.
