(Still head-down, working on the book. Likely to stay there for at least another couple of weeks ...)
Meanwhile, it occurs to me that when the definitive history of the Fukushima Daiichi accident is written, there will be a tally of casualties and fatalities at the end of the book.
I firmly believe that the fatalities will be dominated by iodine poisoning, self-administered by people in countries not exposed to emissions from the plant.
(So far there is one definite fatality at the plant: a crane operator who had the great misfortune to be sitting in the control cab of a crane when it was hit by a magnitude 9.0 earthquake.)
