Radiation in the news

For those of us in Japan, the daily news of radiation being found in the food supply (both in vegetables and in seafood) brings with it more questions and (justified or not) more worry.

In this article from the Wall Street Journal, former nuclear adviser Toshiso Kosako provides a grim prediction of what is to come when the autumn harvest begins in a couple of months.

And this article from Bloomberg, reports that radioactive cesium has been found in Tokyo's water supply for the first time since April. The amount is small, but given that it is the cumulative exposure to radiation that is worrisome and given that we still don't know ALL the sources of radiation that we are being exposed to on a daily basis, what is a level of radiation that can be considered safe?
