Emigration?

Japanese Government has recommended today the rate of contamination by the 3/11 accident on Nuclear Power Plant at Level 7 at last, that's the same rate as the miserable Chornobil Accident in 1986.
From their standing point of view, they were informed by US on the rate of the Nuclear Accident, how much severe that was from the beginning, no matter how Japanese Government had recognized actually or not. Some rumor says US helping proposal was refused at the beginning?
But Japanese Government has no experience on this kind of disaster, just laymen or mob?
Probably, this is the last chance to tell the public the Truth, don't miss the good opportunity, now is the time, so advised by US?
It was a good choice for foreigners to escape from Japan at very early stage.
Living in South Eastern portion as I am, may be better to escape to another country, because Japan land and the thing there must be contaminated with any harmful Radiation Materials sooner or later?
