Exclusion Zone And Criticality
The news from the Japanese reactor incident is not getting better. Why should it? The spew of radiation is still going on.
The International Atomic Energy Agency has told Japan that radiation levels recorded at a village near a stricken nuclear reactor are over recommended levels, a senior IAEA official said on Wednesday.The IAEA guys are not going to be very popular in Japan.
"The first assessment indicates that one of the IAEA operational criteria for evacuation is exceeded in Iitate village," Denis Flory, a deputy director general of the International Atomic Energy Agency (IAEA), said.Save face or save lives? For now a few extra days of exposure are not going to be very hazardous. Unless radiation levels go up considerably. But that is not all the bad news.
In a potentially negative development, Flory said the agency had heard there might be "recriticality" at the plant, in which a nuclear chain reaction would resume, even though the reactors were automatically shut down at the time of the quake.Yep. It might be a minor blip or it could be really serious. But they do confirm that my suspicions expressed at
were not unreasonable.
Why are the Japanese having so much trouble? It may be their Culture.

But it is a serious setback for the world's #3 economy and thus it will be a setback for the rest of the world especially because of the supply disruptions. And we won't notice those (because they are not yet severe) for another month or two. Where will the real hit come? Products for the December holiday season which will go into production (if they haven't already started) by June at the latest.
As to the radiation dangers? They are probably only severe in Japan. For the rest of the world it is the equivalent to a few above ground atomic tests at worst. Not a good thing to be sure. Also not the end of the world.
