I've wondered the same thing, although I have no idea how much iodine-131 is necessary to raise the radiation level to that 200 Bq level we saw the other day. It may not take that much at all, but I have no idea.

The other worrying thing was the discovery of vegetables grown in Tokyo being found with cesium-137 above the legal limits. If the vegetables grown in your own city are becoming contaminated with unhealthy levels of radiation, I'm sure it's making the people wonder about the safety of their own bodies more and more.
