    Report: Fukushima Reactors No. 5, 6 now in crisis — Cesium outside release points up 1,000% in recent days — Local says Hitachi engineers coming to help (VIDEO)

    Oct. 24 — “Though everyone pays attention to reactor 1 to 4, actually reactor 5 and 6 are in crisis. Engineers from Hitachi are coming to the area to get it settled down but it’s concealed. It’s likely that they are going critical so Iodine 131 are measured in Tokyo or Iwate,” said a Fukushima local who has a friend working inside the reactors, according to a summary of his Oct. 21 interview with journalist Iwakami Yasumi in Fukushima Diary. (see video below)

    Just a few days after the interview, TEPCO released new data about Reactors No. 5 and 6.

    Based on that information, Mochizuki is reporting that “Reactor 5 and 6 are in crisis too”.

    The Oct. 23 document shows a comparison of how much cesium was measured at the water release point of the reactors over the past 25 days.

    Over the past few days, cesium levels have increased 10 times.

    In the graph below, the top horizontal line (1.0E +02) is equal to 100 Bq/liter and the line below that (1.0E +01) is equal to 10 Bq/liter. The bottom line is zero.

    For example, Cesium-134 levels on Oct. 20 were slightly less than 10 Bq/liter, while Oct. 23 showed Cs-134 slightly less than 100 Bq/liter.


    Precise measurements for the morning of Oct. 23 are below.

    Cs-134 @ 78Bq/liter + Cs-137 @ 110Bq/liter = 188 Bq/liter of total radioactive cesium
