Fukushima radiation fell on US West Coast and Pacific

Interview with nuclear engineer Hiroaki Koide (translation by Prof. Robert Stolz, transcription by Akiko Anson), published Mar 8, 2016 (emphasis added):

• Now, strontium-90 [Sr-90] has been leaking from Fukushima into the ocean, so it will eventually reach the United States, especially the west coast. This much we are sure of… it is the masses of people who need to realize the impact of the contamination on them. In the case of the Fukushima disaster, for example, they need to be aware that some radioactive material is reaching the North American coast, and the prevailing westerly winds will carry anything released into the atmosphere to the US…
• While we are not really sure [how much radioactive material has leaked from Fukushima] we do know that a portion of this material will ride the prevailing winds across the Pacific Ocean. On the other hand, closer to the ground, the winds will be east, south, and north, and therefore this other portion will fall on Japan―and we can investigate the actual levels here: how much fell on this town, on this prefecture? Adding these up, it seems to be only 2.4 PBq. Which is to say of the total fifteen PBq, 2.4, or roughly only 16%, fell on Japanese soil. If the totals are higher, still a smaller share of the total contamination will have fallen on Japan compared with the Pacific, with the largest portion falling on the west coast of the United States.
• So why don’t we hear complaints from the US? Why are there no calls for compensation? Whenever someone asks me this, I simply say that there just aren’t any such complaints. Why is this so? Well the levels released by the US during the atmospheric testing were tens of times greater than Fukushima. They are the criminals, so they cannot ask for compensation from Japan. The U.S. government does not want to have to reflect on its own past, and I think they are eager to completely avoid bringing up anything like that conversation.
