Iodine-131 now being detected in large amounts almost 200 km from Fukushima meltdowns

Radioactive Iodine in Sewer Sludge in Oshu City, Iwate, EX-SKF, September 7, 2011:

Oshu City is located 187 kilometers north of Fukushima I Nuclear Power Plant.

The city announced the latest survey of radioactive materials in sewer sludge in a sewage treatment center in the city, and it shows iodine-131 being detected in the sludge cake since August 25. […]

The city says it has stopped the shipment of sludge cakes from this plant because of the high radioactive iodine concentration detected from the August 25 sample […]

Here is what nuclear engineer Arnie Gundersen said about the presence of iodine-131 back in April:

Iodine-131 can only come from nuclear fission, and because it has a short life, it disappears after about 80 days.

In other words, the presence of iodine-131 suggests that the [nuclear] fuel has started its own chain reaction without any human intervention.

VIA EX-SKF: From the city's announcement on September 7; original in Japanese, I translated the dates, etc.; emphasis is mine

Though not noted, the numbers in the chart above presumably refer to Becquerels per liter.

    The real news will be if the pendulum readings disappear from reactor 1:

    If so then Elvis has definitely left the building and may be blobbing about…Slinky time.

    Probably still below Unit 1 though and we will see a huge surge in the next three days. Big radioactive smoke (or ground fog as some see it).

    • Steven Steven

      Yep and becoming gradually more visible as the cooler weather sets in…. ahhh belay that, not with the spanking new circus tent around R1 and the venting directed up the stack (and now we see the true purpose of the tent).

  • James2

    Yes, Iodine 131 is 100% proof positive that the nuclear reaction has been in runaway mode sometime in the past 2 1/2 months.

    That’s 3 1/2 months after the accident.

    It’s been observed time and again here as “flashes” of errant criticality, and huge steam/smoke storms.

    And it is 100% poisoning Japan and the rest of the world.

    They are willing to admit to Iodine 131 – because they know that they can come back next month (whenever the emissions stop) and tell us it’s all OK now. But there’s lots more than Iodine 131 out there folks.

    • moonshellblue moonshellblue

      You said it, there is a lot more than I-131 spewing from those criticality’s I think it would amaze a Nuclear Physics expert. They have unleashed a monster. What a species.

  • How come polonium is airborne at 55c
    While you all seem to agree plutonium is Too heavy to become airborne…


    Did you all believe that Particles that weigh .0000000001micrograms more than one and other, don’t take aloft, in comparison to other isotopes?

    That is the biggest laugh I’ve heard today…

    Plutonium particles too heavy to fly lol

    You all don’t get it…

    Which weighs more, a pound of feathers, or a pound of bricks…

    You choose bricks… <— priceless

    • the invisible particles are so heavy, that they fall to the ground…

      Anyone that argues the point of plutonium weigh being too heavy to fly, better have a better explanation than:

        To clarify what I said: I didn’t say that plutonium is too heavy to fly, I was only holding out some hope that it maybe didn’t travel as far, and possibly fell into the ocean rather than made it around the world and into people’s lungs. Not being an expert on plutonium, this is all speculation, although I have heard that plutonium is heavy (dense?) so it doesn’t travel far.

        Some things we don’t know:

        We don’t know for sure how much plutonium was released when reactor 3 blew

        We don’t know what size the plutonium was when it blew, or how far it went

        We don’t know where it is now

        Because of all the unknowns, I am just trying to look at the brighter side of things, since we are still alive. I’m just saying let’s not dig our graves before we know for sure we’re dead, despite the possiblites of how bad this really could be…

      • moonshellblue moonshellblue

        I agree, Dust Fleas I believe is the term used by Arnie for these microscopic particles that ride on the wind, so to speak. But there is no use shifting into panic mode as it serves no purpose and itself is a health hazard. All we can do is take simple precautions and keep living our lives as best we can by helping each other stay informed. Once again kudos to Enenews.

      • arclight arclight

        thinking of the recent arnie and helen diatribe.. 🙂

        the mention of gaseous releases were mentioned…. so of to wikipedia for gaseous plutonium hexafluoride…. under the title
        Fluoride volatility

        has a nice line on gaseous uranium hexafluoride too! as well as others! (now to sit back and watch the sparks fly ….say thank you arnie and helen!! 🙂 )
        peace (sort of …. lol)

        • arclight arclight

          Of course there would have to be a source of fluoride too! 🙁
          “Natural occurrence Many fluoride minerals are known, but of paramount commercial importance are fluorite and fluorapatite.[5] Fluoride is found naturally in low concentration in drinking water and foods. Waters from underground sources are more likely to have higher levels of fluoride, whereas the concentration in seawater averages 1.3 parts per million (ppm).[8] Fresh water supplies generally contain between 0.01–0.3 ppm, whereas the ocean contains between 1.2 and 1.5 ppm.[9”]

            Huntington Atomic Plant Burial Six Months of No Asking, Telling; Radiation Exposure Sometimes Increases with Distance

            published Monday, July 11, 2011
            Vina Colley, a former worker and President of PRESS, recalled an incident in 1978, where a cylinder of atomic weapon grade uranium spilled in Piketon.

            A cylinder was dropped because the straddle buggy used to move it off the line and ready for shipment had been defective, and reported as so, the straddle buggy failed and it was dropped. That cylinder ruptured and it released that 2 pounds of uranium hexafluoride into the atmosphere on that site.

            It was never reported as such in the newspapers…the only reports that ran in the paper was how the spill was minimal, the cleanup right away by work persons on site. There were no alarms.

            “The minimum spill has no counter product that I’m aware of in any military production history; 2,100 pounds in the air. And what didn’t go in the air was piled, they were piling snow on the cylinder because it was very hot, temperature-wise and everything else. And then they flushed that material down the sewers. The servers feed Scioto River. That goes directly to the Ohio River. That has never been addressed as a problem, but in 1979, the year after this happened, Layton Hammond, who owns 1,500 acres on three sides of the plant site, had most of his trees die on one of those sides. But that has never been addressed.Uranium Hexafluoride Process”

            and what about gaseous iodine 129 then? gaseous iodine 131s big brother? Worth mentioning!

            “Radioactivity of French coast of the Channel due to the release of technectium 99 and iodine 129: modelisation and measurements

            Robeau, D.; Patti, F.; Charmasson, S.

            Radioactive releases of Iodine 129 are controlled by measurements of the radioactivity in the liquid effluents before it is released in to the sea from the outlet of the reprocessing plant of La Hague. The effects on the marine environment are examined by a radioactive survey of Technecium 99 and Iodine 129 in Fucus (common seaweed). This radioactivity is measured along the north coast of France from Roscoff in the west of Brittany to Wimereux close to the Belgian frontier. The theoretical study of dispersion of radionuclides in the Channel has permitted a simulation model of the transfer of pollutants and particularly Technecium 99 and Iodine 129 to be formulated.

      The argument that plutonium and uranium are too heavy to travel far is a specious one. Don’t argue from theory: argue from observable data. That is a key scientific principle. The observable data is that uranium and plutonium isotopes travel far from where they are “supposed” to be able to go. That’s the observable data, no matter what the pronuker theory may say.

      Just look at the smoke cloud

      and imagine all the U and Pt and Zr burning up, combining with O2 and being lofted upward by convection from the heat of combustion and the heat of radioactivity. It probably gets a charge on it just from the activity, not to mention movement in the smoke cloud, and then separates into colloidal and molecular-sized particulates. Anything else burning or getting oxidized, or reduced, especially concrete like someone mentioned, and there’s yet more material for it to combine and float with. Chernobyl fallout was very sticky, too, so it could stick to any particulate matter. I know it’s heavy, but it’s not too hard to imagine it acting like ash and soot anyway.

      “You all don’t get it…”

      Unfortunately Tacoma you prove yet again that it is you who doesn’t ‘get it’ by repeatedly underestimating the ENENEWS community.

  • James2

    I didn’t say they were too heavy to fly.

    I said that I cannot find any credible research one way or the other.

    I’ve heard some claim that they cannot fly – too heavy.

    Personally I believe if nanometer P-O2 Particles were released they would fly.

    But I also don’t know if they are still nanometer particles after having been manufactured and operated in the reactor for 7 months.

    During manufacturing, the particles are mixed thoroughly and “sintered” into the pellets. Most sintering processes operate under high pressure and heat, so I cannot believe they actually sinter these particles – more likely they are “glued” together.

    Now when they operate in the reactor, they do reach high temps and they are under some pressure from the springs in the tube – which indeed could fuse the particles into something much larger and much less able to “fly”. This is the bit where I can find no information, and no research.

    I’d say the fate of humanity rests on this question: Did the explosion of #3 release small particles of Plutonium dioxide into the atmosphere or not?

    • Bobby1

      The corium-concrete reaction in reactor #3 enables the plutonium particles to fly. How far? There was some in California. It probably won’t go as far in the same concentrations as strontium, but it’s there.

      • I am inclined to believe, based on a discussion that I saw of the aerial photos of #3’s steam emissions, that some corium got into the sprayed seawater beneath the reactor and blew, setting off the accumulating hydrogen above the SPF along the way, throwing much of the upper building into the atmosphere and along with it, some of that corium, which contained some plutonium dioxide. I think the containment is still there with most of the MOX still inside or underneath, or both. But I do think the USS Reagan encountered plutonium and would not be surprised to find it here (Oregon), along with the cesium and no doubt 200 other such things.

        Alpha emitters, even in tiny quantities, should be taken seriously as they lodge near lung or alimentary tissues and fire their particles through DNA at close range, compromising the gene code. The results make for such ugly photos of the victims that such pictures are commonly suppressed. Those victims could be you or me, though children, infants, pregnant mothers and fetuses make better candidates.

        The child in the movie “Blind” is shown as having suffered from Iodine-131 exposure. The worst, for her, may be yet to come.

  • James2

    That link is dead, but thanks for reminding me that someone has located some amount of plutonium in the US, however it was unclear to me if this was the plutonium from the MOX core.

    I don’t recall Arnie saying anything about the MOX plutonium, as I’ve seen the question asked of him several times and he chooses not to respond. He simply says he doesn’t think the reactor core exploded on March 14th and that the explosion occurred in the SPF – which any first-year engineer could clearly see is wrong.

    I’d like to see the links – as I recall, Arnie said that all the reactors contain some by-product plutonium and it can be released. If there’s more information on the MOX release, I’d like to see it.

    This is important, because the nano plutonium dioxide powder in MOX is the most deadly of the most deadly stuff on earth. The stuff is evil incarnate and should never have been allowed to be produced in the first place…

    THE REASON GOVERNMENTS cannot admit that the plutonium has been released at #3 was subtly revealed a few weeks ago in the article about shutting down the Sellafield MOX facility. It was stated that all the reserves which are mandated by law, according to the arms reduction treaties, have been spent elsewhere and Obama signed a new treaty in April 2010 which allowed the “conversion” of warhead material to MOX.

    So if we shut down the MOX production, then the Unites States is legally disobeying the arms reduction treaties and there are significant penalties associated….

    Plutonium is a alpha particle which can be stopped by a peace of paper! It’s harmful if ingested. So maybe we need start wearing mouth masks (those white dust masks).

    So the plutonium we can stop easy because it’s a alpha particles but..

    The beta particles (iodine 131 strontium-90) is more dangerous. It goes through paper and ½mm aluminium . It can be stopped by ½mm leadpaper.

    • Arizonan Arizonan

      We hear constant refrains from pronukers about how much penetrative power each of the various parts of an atom (alpha, beta, gamma) has as the atom is disintegrating. Nice physics, but basically irrelevant to human life. If you can stop eating and drinking and breathing, you can stop any radioactive isotope from getting inside your body. Otherwise you can’t, no matter what kind of rad it is.

      • Lacsap Lacsap

        Yes start jelling.. I am not pro nuke, just saying if you wear mouth mask you will be better protected from plutonium and that plutonium (which is spoken most of on this site) is less dangerous than iodine 131 and strontium-90 which is on this topic..

    • radegan

      Plutonium is an element not a particle and it comes in many forms and decays into other elements, some much more active, such as Pu 241 to Am 241, a potent gamma emitter. Yes, a paper mask can protect you from breathing it and the alpha particles. Gonna wear it 24/7/365? And what about what you eat? Unless you have special testing equipment, what’s in that salad from Salinas? That glass of water from your tap or well?

      Particles that make it to the jetstream have already traveled to France where Pu was detected from Fukushima. So the question of CAN they reach the jetstream and travel around the globe is settled. Try and think of it as a worldwide mandatory game of Russian roulette – your turn, now eat and breathe.

  • Arizonan Arizonan

    Folks this is huge news. let me ask all of us armchair physicists and the few of you real physicists who come here: how is I131 traveling 200 km from the meltdowns? Is it not a possibility that some part of one of the melted reactors HAS ALREADY REACHED the water table, is periodically critical, and therefore is showing up in reclaimed sewage many 200 km away? I know this is an untested theory, but if you don’t think this is a viable explanation, I would like to hear anyone else’s theoretical explanation of how this can occur five months after “the accident.” This proves re-criticality outside of containment. But how did the I131 get that far away???? Just steam from above or below the plant? Any ideas?

    • Sickputer

      The steam from the gushers is quite capable of completing the job of contaminating all of Japan. The entire island is contaminated… They just won’t admit it yet. It didn’t even require the monsoon winds although that will certainly provide toxic levels that will awaken all the Japanese.

      The water tables and aquifers for human consumption are scarce in Japan as they mainly use surface water to drink. Aquifers are also very slow to spread contaminants. Not as slow as a glacier, but very slow lateral and vertical infiltration.

      It was early August, around 9PM. A worker at Fukushima I Nuke Plant sent an email to his local contact, saying “Steam gushing out of cracks on the ground. The area is foggy with steam, and the workers evacuated temporarily.”

      It is my personal belief that the eye witness testimony from TEPCO personnel indicates that the blob has already reached groundwater. This Eye witness reported large cracks appearing in the ground surrounding the plant, with steam shooting out of the cracks.

      IT’s a new ball game now.

  • americancommntr

    Isn’t it a gas? And rain or snow brings it down?

    It sure appears there is a continuing reaction with products getting into the atmosphere.

    It also appears the former Prime Minister’s statement about his fear was a) a bunch of baloney and b) actually come true. Or he is misinformed, or the stress got to him and burned out his supplies of brain chemicals.

  • luckyjay

    Uhm, mightn’t this be attributable to simple biomechanics – that the (ongoing) irradiated Japanese are simply expelling it as bodily waste? This is sewage sludge , after all.

    Or is that too obvious?

    • @ luckyjay,
      Yes , much of the waist is as you say, but enough will stay in the bodies to cause great harm !
      Sewage sludge was used to make brick and they supposedly stop with making then I heard they continued to make a ship to build, …

      There are a number of articles in back pages about this and as it goes through the body, children have been know to have terribly high reading in their bodies with thought to be safe !

    • Sickputer

      Humans produce some output. The biggest source is the watersheds collect fallout and rain washes into public washing and drinking supplies. That water is flushed as sewage thus producing the concentrated toxic sludge. Then they burn it and spread it even farther by air. The Japanese certainly have a love affair with their municipal incinerators.
