'Anyone living within 1km of the coast near Fukushima should get out'

But I want to make two other points. The first is that the Pacific Ocean is big enough for this level of release not to represent the global catastrophe that some are predicting.  Let's get some scoping perspective on this. The volume of the North Pacific is 300 million cubic kilometers. The total inventory of the four Fukushima Daiichi reactors, including their spent fuel pools, is 732 tons of Uranium and Plutonium fuel which is largely insoluble in sea water. The inventory in terms of the medium half-life nuclides of radiological significance Cs-137, Cs-134 and Strontium-90, is 3 x 1018 becquerels (Bq) each. Adding these up gives about 1019 Bq. If we dissolve that entire amount into the Pacific, we get a mean concentration of 33 Bq per cubic meter - not great, but not lethal. Of course this is ridiculous since the catastrophe released less than 1017 Bq of these combined nuclides and even if all of this ends up in the sea (which it may do), the overall dilution will result in a concentration of 1 Bq per cubic meter. So the people in California can relax. In fact, the contamination of California and indeed the rest of the planet from the global weapons test fallout of 1959-1962 was far worse, and resulted in the cancer epidemic which began in 1980. The atmospheric megaton explosions drove the radioactivity into the stratosphere and the rain brought it back to earth to get into the milk, the food, the air, and our children's bones. Kennedy and Kruschev called a halt in 1963, saving millions.
