This comes as no surprise. The Japanese are zoning off areas as “uninhabitable”.
The most heavily contaminated spot was in the town of Okuma about two miles southwest of the plant, where someone living for a year would be exposed to 508.1 millisieverts of radiation — far above the level of 20 millesieverts per year that the government considers safe.
Yeah, ~510 mSv (51 rem) per year is quite a dose. And yet, in order to kill someone outright, you’d need to give them a decade’s worth of that exposure in a short amount of time.
It’s a terrible, terrible loss. But unlike other catastrophic industrial disasters, Fukushima’s death toll from radiation remains…zero.
