    10 hot particles a day 5 hot particles a day…
    300,000+ bq/m 150,000+bq/m

    Simple statistics implied there…

      A few months ago there was a volcanic explosion in Chile. The ash from the volcano covered a huge territory that even included Argentina. Planes couldn’t take off etc. That ash moved across the pacific very quickly and caused the same problems in Australia.
      Volcanic ash is huge compared to tiny plutonium particles…yet these large pieces of ash made their way all the way across the pacific…intact! They were very much in the same condition as when they started their journey a few days earlier in chile. I think the most important part is you could SEE these particles….where nuclear particles…much lighter and smaller and invisible are also , no doubt about it, are making the same journey all intact and able to cause the same problems in the USA as they are causing in Japan.

    the poor japanese. their p.m. has resigned which i see as him sort of planning to get the hell outta dodge while he can…hopefully the japanese don’t let him get off so easily.

    that picture should show red streaking straight to the right of the picture where the wind was going on those days.

    it won’t do any good to complain i suppose.

    hey, if you turn the pic upside down there is the outline of GODZILLA in red.


    maybe the us nuke fallout map makers can make an upsidedown KING KONG.

  • Obama is in dodge this week too…

    • larry-andrew-nils

      what is the significance of that?…

      • IDk. Kinda coincidental that world leaders are completely ignoring nuclear meltdowns…

        Out of dodge from the public eye…

        Its significant in its timing, and leads one to wonder if our military has access to super computers, that do advanced / futures, weather plotting… (which they do).
        I can’t help but to ask myself:

        Would the disappearance / reclusiveness of world leaders be an indication of events to come… As far as I know the pentagon and the white house are in states of evacuation…

        To me thats worth paying some attention too…

        • That all makes me wonder:
          Are large radiation releases, making area weather patterns more violent. Are the particles really impacting Super cells in our storm fronts?

          & /If so… How colossal are the events to come? Should we expect even larger atmospheric catastrophes in the near future? ect…

          • larry-andrew-nils

            my thoughts are that the radioactive particles are going to change the weather so that forecasting will not be as accurate.

            also, during the first three weeks of fukushima, on a heavy metal-mouth day, the rain came down and then it formed clouds right on the ground… but it was not hot ground in a temperate sense.
            i was thinking at the time that radioactive particles were aiding in the evaporation of the rain which hit the ground thereby making a cloudy mist on the ground which hovered only three feet.

            i’ll bet i am not wrong, as i have lived over 40 years and only ever have seen steam like that hovering when the ground had been hot.

            am i crying over spilled milk ? probably should focus on the future i guess.

    That was only iodine-131, there was also a huge amount of I-132. And the CTBTO (who later retracted it) documented I-135 in ten times the amount of I-131.

    • Hot Tuna Hot Tuna

      Based on new ‘lower estimates’ released by the Japan Atomic Energy Agency yesterday, Cs-137 was about 2% and I-131 about 9% of the total radioactive material released between 3/11 and 4/5. I haven’t heard what the other 89% might be.

      • shockwave shockwave

        I want to know where is the 89% too

        • Hot Tuna Hot Tuna

          Just caught your comment, shockwave. I did the calcs at work yesterday and didn’t have my notes this morning so memory not perfect. Cesium was correct 2%, I-131~ 23% so remaining was 75% instead of 89%.

      Can any of you smart people provide me with an explanation why these intervals between low and high become shorter and shorter over time? And: where will it stop? Will it?
      Thank you!

      Internal gauge at a melted through reactor, even smart guys would be guessing with the paucity of data to draw from. What I can tell you (not that I ain’t no genius) is that I’ve never seen any gauge of any type be “defective” in this pattern. Defective meters either read nothing (most common) or more rarely constantly offscale (representing either contamination or some sort of electrical short. Cycling indicates to me this meter is telling us something (whether that’s corium criticalities, migration, or what I don’t know).

      One interesting theory is a blob of corium with water outside would form a hard crust, the internal liquid corium would then steadily increase in temp/pressure until it achieves criticality, resulting in a spike, and a crack in the crust. The crack would leak a bit lowering pressure/temp and resolving the criticality. Then the crust re-solidifies and the process starts all over. That is 100% conjecture and guesswork and pretty much any other theory probably holds as much validity.

      Tempest in a teacup in the middle of a tornado, really…..

      • larry-andrew-nils

        that is a very concise postulation of what probably is occurring.

        and i suspect this is more than guesswork, and more like educated-guesswork… or psychic knowledge.

        and the water would be steamed away each time the criticality opened the crack in the blob, but this would have a cooling effect, and the blob’s cracks would crust over again.

        And then the reason why the spikes on the graph get closer together could be because the entire lump is actually getting more hot.

        like what if it keeps burrying itself into the ground and down into some recess in some water table edge somewhere… will there be a geyser in the future from the blobs?

        like, a regularly blowing geyser like the one in jellystone?

        hmmm. ancient nuclear site causing yellowstone geyser?

        Maybe each time the tide changes it gets covered? as the core melts father into the ground, more is covered at high tide, making a more pronounced cooling and heating cycle?

        I did no research to substantiate that, just typing out my first impression…

    farawayfan,…that rings TRUE for me,….but like I said,….I’m just glad they raised MR from 70 down to 65,…was getting a tad too close for this ol’e gal! 🙂

    to my understanding, the composition of isotopes released were identical in thier quantities giving a unique and constant signature! so there must be other isotopes deposited?

    this info is obviously being strung out and even completely censored…the big PR is running a mitigation piece for the lawyers to manipulate! this is BP disaster on steroids in all aspects! and the mindshare machine is happily doing its thing!! cant believe that the press can keep quiet about all this! they should be leading the revolution! its thier food being contaminated too!

    bearing in mind the message that europe recieved and was published by the MSM after chernobyl saved alot of disease and death!…this time though…silence! although the scientists at criirad steped up to the plate, as did the norwegians with the nilu forecasts at that time! what/who happened??/rant

    So, that Yellow Rain wasn’t “pollen” after all?

  • larry-andrew-nils

    no. i had some in a bucket and i didn’t think to save it. i dumped it out because i wanted to save my bucket and not have radiation sitting on the water… evaporating ?

    paranoid feeling about real danger… that is invisible.
