Why are Californians buying up iodine tablets?
Same for the Hawaiians?
Seriously - does anyone actually think that a localized meltdown in Japan could exceed what happened at Chernobyl?
Or for that matter - we detonated two nuke bombs in Japan at the end of WWII - and those bombs sprayed particulate radioactive debris into the atmosphere that went all over the northern hemisphere.
There were no demonstrable adverse health affects for any Americans after Chernobyl - and none for Americans after the nukes at Nagasaki and Hiroshima.
Just seems plain silly and a gross understanding of both history and disaster scale by people who are supposed to be ... intelligent?
