The bombs dropped on Hiroshima and Nagasaki casue no problems in the US from fallout and this meltdown seems as though it would have to become much worse than Hiroshima and Nagasaki to get enough contaminated material more than 7 mile in the air to hit the jet stream and stay together long enough to reach the US. Doom and gloom predictions for the US is premature. Even if the map is correct there is nothing we can do to prevent it from happening so why run around in a panic. Even if the end of life on Earth were going to end , in say 2012, there would be nothing we can do about it so why panic and cry over it. There is no way we can build a protective bubble around the US so wringing our hands and worrying over it will do us no good. Just go about our lives and live as full a life as we can until the day we do finally die is all we can do.
