Ａ　緊急炉心停止後も核分裂が継続していた証拠。

①　＞The highest values of radioactivity were indicated on March
16. Thus, the specific activity of short-lived iodine-135
(half-life period = 6,6 hour) reached value of 74 Bq/m3, and
the ratio of iodine-135/iodine-131 activities reached value of
24 that pointed indicated on "fresh" fission products from
the damaged reactors, and also testified to possibility of
emerged uncontrollable nuclear reaction

確か、高崎観測所は、Ｉ－１３５は誤検出だったと逃げました。

②　＞Interesting data in favor of the criticality is given in [5]
where the results of the determination of radioactive sulfur-
35 in sulfate aerosols and gaseous SO2 in the oceanic air on
the Pacific coast in the village of La Jolla, California. This
data indicate exposure of sea water to neutrons with fluence
4 x 1011 neutrons per m2http://www.pnas.org/cgi/doi/10.1073/pnas.1109449108

４Ｅ＋１１／㎡の中性子線量は、臨界状態におけるオクロ天然原子炉に想定された
中性子線量と比べても、十分な値だ。

③　＞data on Fig. 11 also indicate possibility of
emergency emission products supply with "fresh" fission
products, i.e. supports a hypothesis of postshutdown　criticality

Ｂ　福島原発事故における放射性物質の放出が、主に複数回の核爆発的な性質を持っていたことを示すＸｅ－１３３とＸｅ－１３３ｍの比率。

＞Fig. 11 indicates isomer ratios 133Xe/133mXe, recalculated on
March 11, using mesurement results from Richland [6]

＞The value of the 133Xe/133mXe isometric activity ratio for the stationary regime of reactor work is about 35, and that for an instant fission (explosion) is about 11, which allowed estimation of the nuclear component of the instant (explosion) energy release during the NPP accident.
