    Could they give us a clue about what this stuff is?
    Animal, mineral, vegetable??

      There are scientists. They have names for everything, like oxygen, carbon, water, oil, granite, moss, tar, sugar, starch, blood, diamond, aluminium, DNA…

      And there are nuclear scientists. They have names for everything like…substance.

    • NoNukes NoNukes

      "Corium (and also highly irradiated uranium fuel) has an interesting property: spontaneous dust generation, or spontaneous self-sputtering of the surface…"

        Highly radioactive Cyanobacteria is what the black substance has been called. I also think it is from the corium's as I have witnessed very black smoke seeping between the reactors many months ago. TMI and other melted cores have also had bacteria form on them.

          The black substance could be a combination of many things.

          [1] Could be from the burning of radioactive waste.

          [2] In Chernobyl, they found "black, melanin-rich radiotrophic fungi" "growing on the reactor's walls."

          [3] After Chernobyl, a black-rain fell.

          [4] If cesium was found in the black substance, you can bet plutonium is in there.

          What are the ratios of cesium to plutonium usually found?

          In Nevada, they found:

          "… radiocesium and plutonium give activity ratios of radiocesium/plutonium that range from 0.7 +/- 0.1 to 27 +/- 2 "

          From nuclear fallout:

          "the world-wide fallout ratio of 34 +/- 4 "

          So, 45,000,000 Bq/kg of Cesium was found…. you can do the math and see how Plutonium is hypothetically there, too.

            What I'm not getting is they keep regurgitating this story-line the past two years, haven't they SINCE scientifically examined the substance yet?

            I mean come on, we would have had a DNA test back by now.

            If they are saying they cant identify it, well, that also is kinda off kilter. Are they saying it does not contain elements found commonly on the planet then?

            Something smells fishy to me, scientifically speaking.

      • Johnny Blade Johnny Blade

        There's been consistent reports from far & wide of "toxic algae blooms","cyanobacteria" was used more than once to describe the growing phenomena that I've seen for myself but didn't know what I was looking at at the time here in the lower Great Lakes region associated with fish kills in small bodies of water and perhaps related to the growing number of dead birds I've neen noticing for a bit over a year now(?)!
        I'm sorry my short-term memory is malfunctioning at the moment and I can't recall who recently posted an article on a govt.(?)scientific website which the poster suggested "answers could be found in the scientist chat forum" regarding dust/pollution ATM(Airborne Transport Modeling)from 2007(?)with manuscripts from interviews between science/technology magazine reporters and a research team aboard an aircraft from Boulder,CO flying to Japan & back to track & analyze "plumes"from Asian industry with very detailed and "surprising" findings in some cases including a "black substance" that traveled a lot further,faster and in greater quantity than previously noted. I think the "old" 2007 info/website holds a FEW "answers" to several key questions & contradictions and wish I had saved & bookmarked the original post & link that my pc's AV software "cleaned" from my history & I hope the person who posted or anyone else who remembers it sees this & re-posts the link?!!("NSCAR" ??)

      I've posted this before..still waiting for some of the TEPKILL/JapGov bailout $$$ to be spent on some proper research on the black plague substance' which seems to be increasing in concentration…

      Is it possible that these bacteria are same or related to the earliest cyanobacteria lifeforms on earth that sequestered radioactivity into the ores that are now mined to concentrate into fission products. Perhaps we are seeing a simple process of 're-emergence'. Like any opportunistic species, 'plenty' (as in 'lots of') may be stimulating a population explosion, similar to algal bloom in a waterway with excess nutrient in it. Now that there is a massively increased 'food source', so there is a 'bloom' of the cyanobacteria that were only 'subsisting' all these millions of years.

      Are we watching the 'repeat re-engineering' of the planet? After taking billions of years to sequester radiation and produce oxygen, thereby creating our atmosphere which protects us from space radiation, we have reintroduced acutely toxic radionuclides within our atmospheric defensive membrane? Human intelligence test = epic fail.

      • omniversling


        This could be more likely than the fallout from incineration, or fallout flake from the steaming coriums of Units 1 and 2. Unless that is being very rapidly transformed into cyanobacterium 'nutrient'.

        Radioactive black dust was also observed and measured at the British nuclear tests in Australia in the 1950s. Is it possible that this is a result of the MOX fuel in U3, which I understand is similar in composition to some early weapons test material?

        I've also read that the black substance is the oxide ashes formed when they make a cheap plutonium bomb that uses lots of uranium in proportion to Plutonium. The salient point of this is that the MOX ratio of PU is about the same as the early bombs (as I understand it), about 7-10%).

        You can see a reference to it here as the black substance rained down on australia during the Maralinga tests. Go to about 13 minutes into the video and listen for about 1 1/2 minutes. You will be shocked. The out of control reactors in Fukushima (U3 at least) are burning cores made up of weapons mixes.

        omniversaling, i'm so looking forward to when you get beyond your use of racist terms about the Japanese.

    OK, all kidding aside. THIS is some HOT stuff. Probably from the heavy corium smoke, probably deposited by rain. Stuff like this will kill dead all the Japanese who remain in Japan over time. If I were there, and learned that this stuff was in my town, I would find a way to leave. Take a bus, drive the car, or walk. People will not live for long with this stuff in the air, in the food, and in their bodies. TEPCO, what is the PLAN for cleaning up THIS?

    • m a x l i

      @PhilipUpNorth. Until scientists tell us anything, I will come up with some speculation. My totally wild guess: radioactive hot spots combined with dead bio matter, some form of "life sink" or "death trap". It goes like this: Radioactive substances are settling on ground. Tiny life forms of many kinds, which are abundant everywhere, die. New tiny organisms, like bacteria, mold, fungi…are drawn in to this source of food, will die again, and so on, and so on…

      If it is not yet clear, imagine some imaginary super poison somewhere in the savanna. Soon you have a dead antelope. The carcass will draw in some hyenas, wild dogs, vultures. After a short while you have dead hyenas, dogs, vultures, which will be spotted by more hyenas, dogs, vultures, and so on…

      This works as long as there are surroundings, that are relatively less contaminated and can produce new live.

      Maybe they call it "substance" after nearly two years of "research", because if they would call it dead organisms/former life which is now dead/dead life/killed live, it would not be the best advertisement for the nuclear industry.

      As I said…my wild speculation.

          Thanks, papacares! But it is too early to announce the winners of the medals, as long as we don't REALLY know what it is.

      • Misitu

        Near enough.

        Earlier results showed some of the black stuff to be cyanobacteria (bluegreen algae). The arguments set out above are about as near as we can get without personal expertise. And the lack of obvious clarity from researchers is about as damning as can be got without publication of analyses.

        Damning indeed. If these researchers were cats they would be eaten by mice.

    So out of curiosity, has there been any group that has been doing soil and water analysis around the globe since last year?

  • TheBigPicture TheBigPicture

    Look in Tokyo.

  • bwoodfield bwoodfield

    I found this article interesting; it's not about the movement of radioactive material across the pacific, but rather dust and microbes.

    "It's been estimated that about 7.1 million tons (64 teragrams) of aerosols — dust, pollutants and other atmospheric particles, including microorganisms — cross the Pacific each year. The aerosols are carried by wind storms into the upper reaches of the troposphere. The troposphere, the layer of air closest to earth up to about 11 miles (18 kilometers), is where almost all our weather occurs"

    So with the black "substance" is showing up in Tokyo, as previous articles have indicated, it's not improbable to see it crossing over the ocean to N.America.

    Sciences versus science.

    There are different types of sciences and some of them actually try to be real science.

    For example you have nuclear science and medical science. Medical science deals in percentages ex. A new drug is created and testing on subjects results in making 10% ill, kills 5% and 5% show no affects during trials, the new drug is declared a success because 80% of the trial has the desired effect. Congress is lobbied to insure against or limit liability or allow waivers against the 'anomalies' so the new drug can be approved and sold. Hardly scientific.

    In nuclear sciences you just ignore results that interfere with intended conclusions or avoid doing contrary testing altogether.

    In real science, the 'anomalies' are the most fascinating and deserve the most attention for investigation. Why did some die, why did some get ill and why did some walk away unaffected? Until you have those results, complete science is lacking.

    Here they have discovered a highly radioactive "substance" that either borders on being boring or they know exactly what it is and are not telling the public. The science of panic…no such thing.

    40 MILLION decays per SECOND in 2.2 pounds of black substance.
    Only Caesium 134 and Caesium 137 out of over 2000 radionuclides?
    Just think of what the real total is, with the other actnides added.
    Does anyone here have a geiger counter that can register 40 million decays per second?
