I'm quite willing to admit that the ones within the same distance will be the ones who are similarity affected. Chernobyl stopped spewing radiation, there is no 'guarantee' that these ones will be capped by the end of this year. Should it go on that long (at present rates) how much will eventually be released. Just because you are safe are you saying the subject doesn't deserve to be 'explored'? Do you downplay all the dangers, short term and long term? Here is one more vid about Chernobyl, if it's false then you should buy up all the properties in the 'hot zone' and rent them out once the Gov declares it 'all clear'. Think of the money you would make, .....at least until the law suits started.

As we would only get a 'tiny amount' you are right it is no big deal, until you add in all the other 'stuff' that tends to make the body weaker, say some GMO pesticide and a few other things like mercury in vaccines and you just might have to be a tad more concerned over each of the parameters individually.
As the **** had hit the fan on day one, I hope they did the evac needed even if they lied about the severity of the 'known situation'. If nothing else the public (in Japan) should be insisting on 'watchdogs' checking all given data and given access to requested data that is available. If the Gov was ready to ditch Tokoyo as the operating center then they could also be lying when they say the move is for other reasons.
