Gov’t model shows Fukushima radioactive gas near Tokyo skyrocketed to 10,000,000,000 times normal levels soon after 3/11 – “Very high concentrations” recorded at all monitoring posts in northern hemisphere (VIDEO)

Published: March 18th, 2015 at 10:15 am ET


Based on video from a November 2014 presentation by Roland Draxler of NOAA Air Resources Laboratory (powerpoint document):

  • Video from Slide #4: ‘133Xe Example‘ – Xe-133 Air Concentration (kBq/m3) [kilobecquerels per cubic meter] from March 14-16, 2011 averaged between elevations of 0 meters and 100 meters with release starting at 9:00 am UTC on March 14, 2011
  • The red dot shown on the maps during each 1-hour time interval appears to signify the location with the maximum air concentration of radioactive Xenon-133 coming from Fukushima Daiichi. Maximum amounts are noted below the color key in the model video.
  • From 3:00 pm to 7:00 pm UTC on March 15, the red dot is located between 10 to 20 kilometers from the border of Tokyo Prefecture (outlined in red on maps to right). This location is 250 kilometers from Fukushima Daiichi.
  • The maximum air concentration during this 4-hour time period ranges from 800-1,800 kBq/m3 (800,000-1,800,000 Bq/m3).
  • Since 2008, the average Xe-133 air concentration** recorded at the CTBTO monitoring station nearby the location of the red dot has been 0.00016 Bq/m3.
  • > The Xe-133 concentrations near the border of Tokyo Prefecture on March 15 shown in the NOAA model are between 5 billion and 11.25 billion times average.

** Source: Study titled ‘Radioxenon detections in the CTBT international monitoring system…‘ published Feb 2014: “Five years of station history for 133Xe… measured at RN38 in Takasaki, Japan [50 km from location of red dots near Tokyo]… consist of 2,820… samples, collected from July 1, 2008 to May 18, 2013… The isotope 133Xe is detected in 60% of the samples, with an average activity concentration of 0.16 mBq/m3 [0.00016 Bq/m3].”

According to this study on the CTBT monitoring system, “the Fukushima event caused very high concentrations in all noble gas systems in the northern hemisphere.”

    Good morning!

    Muon imaging results were released finding no fuel is left in Reactor Vessel of Unit 1.

    The bottom of Reactor1 has holes in it.

    Admin.: this topic deserves a new thread!

    Where is the damn corium, eh, TEPCO? 😉

    • PhilipUpNorth PhilipUpNorth

      Oops! Just spotted rogerthat post on muon results.
      Just what we expected those results to be.
      Waste of time and muons, if you ask me.
      Muon imagery won't work below ground level.
      All melted fuel is below ground level.
      So, all a big waste of time.

      Way to go, SimplyInfo! 🙂

        Oh, but Phillip…They now know one place that it isn't.

        Actually, they had to have known all along. If there's such a hole in the bottom head the RPV can't hold water. No water can be possibly returning through the RPV piping.

        • Note:
          I posted the results to admin a week or so ago. There wasn't a corresponding article to attach with the results; Hence it not being up yet. (it was just the pdf).

          Either way. The research is effective, and Shaker made the best point of argument one can make.
          Water goes in A. Does not come out B. There is a variable of X. Find X to solve.

          IMO the Muan tests were performed awhile ago. Did you guys see the date on the pdf…?

          • I was really confused that everyone released that the report came out from tepco today, being the pdf shows that the reactor was tested in 2012.

            Or am I being bad again…

            • Shaker1

              Tacoma, what you may be seeing regarding that PDF is that it's part of the proposal LNL put together to image the cores, not the cores themselves.

              But, hey, in this situation, who knows?

              What's rather obvious to me is that they can only put water into the RPVs through it's design features intended to do that, be it the normal inlet or the emergency systems. If they're not getting very, very contaminated water back from that filling, it's going somewhere else. I might think the water they might recover from the buildings themselves if from those leaky turbine buildings, a mixture of groundwater and whatever they introduce. The rest goes to the sea. And, at any rate, if the piping was undamaged, they could have closed valves and given the RPVs even slight pressure to check the integrity. Testing pressure vessels, one just doesn't bring the fabrication to test pressure, then instantly release. It's left at pressure for a while. If the pressure decreases during that time, there's a problem.

        • They are using the basements and trenches as the 'return'.

          There is no pressure in any of the melted down and out reactors.

          Holes in all of them.

    Ummm. Time for another gathering around a large cherrywood conference table where various hominids scratch their heads as they frantically generate new powerpoint presentations to each other to calm the masses that
    TEPCon has everything under control despite the fact that Unit #1 has NO
    FUEL visible in the reactor well.

    Some hydrogen explosion!

    Maybe it is time to raise the white flag.

  • Nick

    Now what? I am going to have to get up to speed as to what we may be facing. Up until now, I gave TEPCon the benefit of the doubt while they
    did the muon test.

    I have a hunch that Unit #2 and Unit #3 are worse. Not that it matters since we know things are FUBAR.

    If you are in Japan, I HOPE you are getting necessary info despite the State Secrets Law.

    Anychance social media will relay this info about Unit #1? Facebook is on board. Others?

      I downloaded the translation of Nato Kan's interview and it's well worth the read. While it's obvious that initially management of the situation was horrible, it really doesn't seem much better on purpose. We all know why. At some point, Abe is going to be the most hated man if Japan. He's be remembered for none of the reasons that he might wish.

      Here's a quote from the end of the interview:

      "…right now people have lost faith in politics, but in the end, it is the people who must decide. Whether you think it will be alright and worth the risk, or you think it is too dangerous and want to do away with the risk. Of course, you obviously need debate among the experts, too, and I may be over-generalizing, but in terms of domestic issues, in the end the ones who have the most at stake — people, the electorate — must decide on it all, including the risks"

    • Shaker1

      And, Nick, here's the link to an unofficial translation of that interview.

      The point I'm trying to make here is that social media is informative, but the point of action doesn't lie within these networks. I seriously doubt that anyone is truly oblivious to what is happening, nor do I think that one should get so involved in the technical aspects of this. It's simple and obvious. Politically, no one needs a technical excuse. All the electorate as to do is make the commitment to be adamant that they don't want it. One has to get into the streets.

      "There is the economy of private life in the home. But this is not the proper sphere of man’s activities as a being of logic, of courage, and of wisdom. It is in the public and political realm that he shares words and deeds, thus contributing his share of action and thought to the fabric of human affairs."

    When TEPCO ran a video camera into a hole drilled through the wall of Containment2, they were surprised to find very little water in the bottom.
    "Inside the Fukushima I Nuke Plant Reactor 2 Containment Vessel, 1/19/2012"

    TEPCO was pumping hundreds of tonnes of water into the containment vessels every day, but it was leaking out through big holes through the floor of the pedestals.
    This year, TEPCO plans to shoot videos of the pedestal area in Reactors1-3.
    IMHO, they will find only corium residue around a big hole at the bottom.

    How many years will it take before TEPCO gets a video of the holes in Basemat1-3?
    At this rate, we will be 8-10 years into the Fukushima Disaster by the time TEPCO admits that there is no corium left inside their three reactor buildings.

    Where is the damn corium, TEPCO? 😉

    Tepco and the media are admitting the true magnitude of the disaster at Fukushima in baby steps way after the fact. This is putting people in danger for lack of information. If they admitted the truth right away, steps could have been taken to move people to safety. As it is, it's too late. Probably for all of us. I am beginning to think the people who are uninformed are the lucky ones. However, our govt should be testing food and relating radiation levels to the public in real time. Those two things could help us keep children out of harms way for awhile. WTF good is govt if it can't even do that?
