Iodine-131 from latest criticality.

I wanted to update a previous post, New criticality, from Aug. 24. Some sludge data has come in, and there has been a severe spike in Chiba prefecture. Gunma did not have the spike… Chiba is located to the south of the Fukushima Daiichi plant, while Gunma is located to the west of it.


These readings were actually take on August 20. The previous reading at Chiba was on August 6… so the iodine could have been deposited anytime from this date until August 20. This youtube video shows activity at unit 3 on Aug. 7. More activity on Aug. 15, possibly originating from the common spent fuel pool. This picture from August 20 shows more steam, perhaps originating from the sea itself. And the viral picture of the boiling sea, I think was taken on August 27.

On September 2 it was reported that the tanks with the treated water emit 1.0 sieverts/hr of beta radiation due to strontium-90, which causes bone cancer, leukemia, and immune system damage. The graphic of ocean currents indicates that Hawaii is in the path of these radionuclides, which have already arrived. It has not made it to the west coast yet (still a few months), but the contaminated water will make a right turn from there. It will then turn back and contaminate the tropical Pacific, polluting the waters off the Philippines and Taiwan.

UPDATE: Tokyo sludge from the period August 14-30 contained up to 57 Bq/kg of iodine-131.

  1. What the Fukushima?! 10 Hiroshima’s An Hour (Video)

    Dr. Patrick Flanagan, 1997 scientist of the year and founder of Phi Sciences, discusses the disaster of Fukushima in the video below, and explains that the Fukushima situation is far worse than we’ve all been led to believe.

    Flanagan claims to have data that says “Fukushima is putting out, every single hour, the equivalent of 10 Hiroshima atomic bombs, radiation, every single hour, 24 hours a day.”

  2. Shimatsu says that the villagers have told him that weapons labs are spread all over, in the mountains, etc…..

    the site is oatmeal…it is crumbling…the piping isn’t going to take the strain anymore…

    massive amounts of tritium are being produced…

    There is another source outside the reactors pumping radiation…

    uranium and plutonium are higher *outside* the site…from some other source, outside of Fukushima I….very highly enriched plutonium and uranium…

    War grade material…pouring out…ultimate danger…

    there are thousands of workers on the roads…but around the plant you see one or two guys…

    there is a massive amount of secret work that has nothing to do with the Fuku I reactors…not one word mentioned by Japanese gov’t, Tepco, Japanese military…

    another facility is releasing into the ocean…

    Fukushima has wiped out the ozone layer…and threatens to wipe out the Pacific as a source of life…now is the time for the Japanese gov’t to tell us what has really been happening…how much war head material is there…10 tons a second being pumped out…large parts of North America will probably have to be evacuated…this committee is already worried about…another massive explosion…

  3. This was during the latest criticality:

    Atmospheric dose in reactor4 rose by 1.2~1.6 times / Tepco “Dust from reactor3″

    Because they detected the increase of ambient dose in reactor4 from 8/9 to 8/19/2013, they suspect the radioactive dust from reactor3 increased the ambient dose in reactor4 as well.

    Kyoto Uni Prof. “Tritium might be discharged directly from the reactor3 to the atmosphere”
