The sensationalism, ignorance and scaremongering in what is being reported and said at the moment is so bad I can't believe it.
The only people who will be significantly affected by what happens to the Fukushima reactors will be the workers still there and the townspeople. It will not affect Tokyo. It will not affect other countries (except by people hijacking the incident for their pro- or anti-nuclear causes).
An oil store exploded in Chiba, releasing huge plumes of toxic smoke, yet nobody said anything! I live in Fukuoka, where we are regularly told to stay indoors because of toxic clouds of chemicals drifting over from China, yet people are worried about receiving a tiny amount of radiation in a city that is very polluted!
Currently, there are half a million people in shelters in the north of the country,
800,000 without electricity, 1 million without water and a death toll of 11,000+ and people are worried about something that would have only a fraction of the effect of smoking a cigarette or having an X-ray, at its very worst.
If those things don't drive it home, check out how many earthquakes have hit since Friday on
this map. There are millions of people afraid to go out or sleep who are stripping the shelves of supermarkets in a panic (even here, at the other end of the country) when half a million people up north don't have any food, water or gas.
