Kaku’s statements about the exposure due to I-131 is off base. This fission product has a half life of about 8 days. It is mostly out of the picture, unless a new criticality occurs. He does not address this issue. If a new criticality were to occur a much larger region in Japan may become contaminated. If the criticality happened and conditions were appropriate to allow a super critical chain reaction, a nuclear explosion would result and would likely result in even more wide spread contamination IMHO.
I consider that the most likely health issues will result from mobile radioactive isotopes with relatively long half-lives contaminating the ground water. These include C -12, I-129, Se-79, Sr-90, Tc-99 Cs-137 and radioactive actinides soluble in water as a carbonate complex ion. The geochemistry at the site effects the concentration of the complex carbonate ions. The “nuclear village” in Japan is the biggest issue the population faces IMHO. Kaku does a reasonable job of identifying this problem.
