Oct. 31 — “The Ministry of Education and Science announced on October 31 the ‘result’ of the survey they did in June. Much like announcing the result in July of the survey they did in March about radioactive fallout in Tohoku and Kanto, where radioactive iodine, cesium tellurium and silver were found in abundance in Tokyo,” reports EX-SKF.

The half life of Silver is about 250 days.
“Silver-110m probably came from melted control rods, and went all the way to Tokyo,” notes EX-SKF.
