Recent disclosures of tons of radioactive water from the damaged Fukushima reactors spilling into the ocean are just the latest evidence of the continuing incompetence of the Japanese utility, TEPCO. The announcement that the Japanese government will step in is also not reassuring since it was the Japanese government that failed to regulate the utility for decades. But, bad as it is, the current contamination of the ocean should be the least of our worries. The radioactive poisons are expected to form a plume that will be carried by currents to coast of North America. But the effects will be small, adding an unfortunate bit to our background radiation. Fish swimming through the plume will be affected, but we can avoid eating them.
