@Seth I think you're over reacting. (pun not intended)

Saw someone post this somewhere else. When the explosions first happened radiation spiked to the equivalent of eating 30 bananas a day for a year (which is crazy, but not likely to kill you from radiation poisoning), and now it has dropped back down to eating 1 - 2 bananas a day for a year.
Unless you're equally worried about the radioactivity of bananas, I think you're gonna be alright.
