MIT is mad. After the New York Times published an amazingly irresponsible map, MIT called them on it. The map makes it seem like America is getting slammed with radiation from the Fukushima reactors, when, in truth, the radiation reaching the U.S. is "barely detectible" and no threat to anyone's health. But you wouldn't know that from the map. The first time I saw it, I wanted to run to my fallout shelter and batten down the hatches. Then I realized, I don't know what "batten down the hatches" even means. Anyway, the text in the New York Times article does clear things up, but that doesn't excuse a really deceptive map. Just ask MIT—their full assessment here.
