IEER: "Seven major sources of radioactivity still pose a considerable threat to people in Japan."

The Asia Pacific Journal's “Long Since Passed the Level of Three Mile Island – The Fukushima Crisis in Comparative Perspective" spotlights The Institute for Energy and Environmental Research (IEER) head Arjun Makhijani's March 25, 2011 analysis of Fukushima radiation emissions:

"Whatever the ultimate estimates, it is clear that the Fukushima accident is far beyond the U.S. Three Mile accident in 1979 in every respect, and much closer to the more terrible Chernobyl accident.

Fortunately, much of the radioactivity has been blown over the Pacific Ocean and by the time it reached North America the plumes were very dilute. They were even more dilute by the time they reached Europe.

Unfortunately, much of the radioactivity ahs also affected food and water in Japan. Sadly, the accident is not over and the situation is not yet under control. Seven major sources of radioactivity still pose a considerable threat to people in Japan. That is a completely unprecedented situation. I deeply appreciate the struggle of the workers to contain this terrible accident, for they have been able to prevent an even worse situation from developing."

TEPCO, the Japanese government, and other organizations have been getting more open with data, but many important documents are not being translated quickly and there is little effort to bring the findings together in an easily understood way. See here for TEPCO’s analysis of the radioactive water in the No. 3 reactor building. Satoko Norimatsu has provided English translations of the compounds being measured...

Here (in Japanese) is Japanese government (Nuclear Safety Commission) simulation data that estimates that some areas have already reached the threshold of internal radiation exposure at which iodine tablets become necessary to reduce cancer risk.
