Japan Times (Hotline to Nagatacho — Brian Victoria, Kyoto), Nov 4, 2015:[Former Japanese ambassador to Switzerland, Mitsuhei Murata, recently proposed… for Japan to stage an “honorable retreat” from hosting the 2020 Olympics… In the September issue of Gekkan Nippon, Murata… noted the danger still posed by large numbers of spent fuel rods suspended in spent fuel pools in reactors 1, 2 and 3 [which] can’t be removed from the damaged reactor buildings due to the high levels of radioactivity surrounding these reactors… Murata’s gravest concern is a number of troubling indications of recurring criticality [ i.e. uncontrolled nuclear chain reactions] in one or more of the reactors at Fukushima No. 1. For example, he notes that in December 2014, both radioactive iodine-131 and tellurium-132 were reported as having been detected in Takasaki city, Gunma Prefecture [~130 miles SW of Fukushima Daiichi]. Given the short half-lives of these radioactive particles, their presence could not be the result of the original meltdowns at Fukushima.
