    Does this mean the cores vaporized and precipitated into the environment and are no longer on site and we don't have to worry about china syndrome, I don't no, clarify please.

    • StPaulScout StPaulScout

      "China Syndrome" is far preferable to the cores vaporizing. Once vaporised, they are free to go where the wind takes them. That means they went east, towards the U.S., Canada, Europe, Russia, China and eventualy back to Japan. Since the wind never stops moving, neither will the radioactivity. It will blow around and around the world until it eventualy settles out. All land and water will be contaminated to some degree. All animals and plants will be contaminated to some degree.

      • weeman

        That is what I am afraid off complete vaporizing of cores to the environment, if the cores liquified it is one step from vaporized yes no, I am looking for answers.

    this is a demo for the gieger counter
    comes out 19 months after measurements?
    the interview on the gadget on the link at the end of the video was even more intersesting
    the need to be able to measure down to 10 Bq/Kg in food.. when asked "what is a safe level in food" the guy replies that that has to be determined by the specific countries..

    he doesnt mentionthe levels allowable in the usa?

    1240 Bq/Kg with a variability allowance that could take it higher than that according to "Codex Al.."

    @9.30 in approx

    and i have difficulty with my computer response when i am on the site webpage?? might b ok for you..

    horrible and it has half live 24.000 years

    • guezilla

      Don't worry though, eventually it'll all decay into Uranium-235 with half-life of only bit over 700 million years.

      That said, there's two BIG questions I have about their data… First, it's quite unhelpful the isotope readings are missing any kind of indication about units. I was browsing through the sites for a while, but couldn't find anything about what kind of units they could be using (I probably need to listen to that video). Assuming they're related to conventional Bq, Pu-239 has almost 800 times the half-life of Cs-137, so in that case the Pu-239 reading needs to be multiplied by 800 to get relative amounts.

      More significantly, there are many measurements where the Pu-239 level is much higher than featured here (37.25555 140.986143: Pu239 743.18, no other isotopes) but I can't find any where Uranium was identified. Because the MOX fuel has both plutonium and uranium, this doesn't sound credible. They do have different chemical behaviour though, and could disperse differently.

      With a 0-reading it's likely the meter is mis-identifying the gamma peaks belonging to something else, probably Cs-134 and I-131 because they're not included in the results list yet would have been present and the company advertises firmware change to "quickly identify them".

      Also, the actual measurements are from Global DIRT, not Berkeley Nucleonics, who are just the manufacturer & advertiser of the measuring device.

    These types of findings, interfere with indoctrinating school kids into the world of nuclear power generation.

    Hand held devices telling you more than you need to know but government via military satellite readings are top secret.

    That area with those readings is a wasteland for centuries to come.

      You said it a wasteland for centuries what has man done? I'm still trying to hang on to hope but my grip seems to slip more each day.

    "Plutonium-239 levels were almost as high as Cesium-137 a dozen kilometers from Fukushima Daiichi (PHOTO & VIDEO)"…. Why *were* its not in the past… isotope, Pu-239, has a half life of 24,360 years. Not leaving anytime soon, Also as a reminder for you. Plutonium – named after Pluto Lord of the underworld.

    I guess I shouldn't have such a suspicious mind. Those hit and miss statistics are just a bit too convenient for me:

    Of course maybe watching 1984 tonight on Netflix is bringing out paranoia. 😉

    The GD folks just descended on my awareness and I'm not in a place to do thorough research.

    This bit on another GD venture kind of struck me oddly:

    "The film follows a United States Army Airborne unit to one of the most dangerous places on earth, where patrolling is not only about killing insurgents but also about educating the people and winning their hearts and minds. Tasked with an impossible mission in an unlivable section of war-torn Afghanistan, Restrepo makes the audience live the life of an American soldier for 90 minutes…"

    Also the BNC host webpage referenced by the GD Enenews listing shows a prominent hyperlink labeled "Updates from Japan- What We Know".

    Which leads to an old inaccurate article from Scientific American four weeks into the 311 crisis:

    What You Need to Know about the Japan Nuclear Crisis [Updated]

    Containing BB gems of radiological excellence like this:

    "you would need to eat 16 kilograms of the tainted fish meat in a year to get sick. "

    "Wearing masks and respirators prevent the ingestion of radioactive particles."

      I also notice the spottiness, not only that but the map description itself says "The map below represents only readings which contained isotope levels (about 2000 of the 2900+ current readings)". Besisees attesting to the extreme spottiness of the readings, why are they throwing away data? It would be immensely helpful to also see areas measured as being low-radiation, in fact that was one of the intended uses hailed in some press release.

      Now fallout will generally occur where dense airborne releases and rain co-incide. It is not unusual to get rain-spots limited to one small cloud, so somewhat spotty fallout is possible. But 743 units of Pu-239 at one point, and suddenly it's just Cs-137 right next to it? IMO this speaks more to a sloppy analysis firmware than actual information, and as said Pu-239 would still be there to measure.

    Known as Japan’s “Shadow Shogun”, Osawa is no Chicken Little. He was a major reforming force in Japanese politics as president of Japan’s main opposition party, the Democratic Party of Japan, from 2006 until May 2009. In an interview with Osawa on May 26, 2011, Osawa echoes Dr Caldicott’s fears that Japan may indeed become uninhabitable.
    “Some day we may not be able to live in Japan. There is the possibility that the power plant can reach the state of criticality again. If it explodes, it’s a huge matter. Radiation is being leaked in order to keep the reactors from exploding. So, in this sense, it’s even worse than letting the power plant explode. Radiation is going to be flowing out for a long period of time.
    “This is not a matter of money, but of life and death for the Japanese. If Japan cannot be saved, then the people of Japan are done for. We can always print money. Ultimately the people will have to bear the burden.”

    Osawa slams the Kan administration for putting together a team made up exclusively of people who depend on nuclear power to make a living, referred to as “members of the nuclear mafia”.

    “Did you see all those scholars saying “the crisis is not so terrible,” “won’t harm the health at all” on TV? What they say is meaningless because they depend on nuclear power for their livelihood.”

    “..the government doesn’t tell the truth…”

    On March 13, the radiation levels were so abnormal that even a portable survey meter could tell. The Ministry of Education and Science has the nuclear research lab [JAEA?] and there are specialists who measure radiation.

    According to NHK's ETV, the Ministry of Education measured 333 microsieverts/hour in Akougi in Tsushima District of Namie-machi. The normal levels were 0.03 to 0.06 microsievert/hour. 1 millisievert in 3 hours, 8 millisieverts in one day, and in 3 days it would have exceeded the current standard for evacuation
    [20 millisieverts]. If you stayed for one week, it would have been the level which "would affect the health immediately". It would have been the level not even the nuclear plant workers are exposed.

    The residents continued to live there, knowing nothing. Tsushima District of Namie-machi is located at about 30 kilometers southwest [sic. it is northwest] of the plant, and many people inside the 20-kilometer radius evacuated there after the evacuation order was issued on March 12. They were supposed to have escaped from radiation, but they ended up getting irradiated several tens of times more.

    Each year a typical 1000 mega-watt (MW) commercial power reactor will produce 300 to 500 pounds of plutonium — enough to build between 25 – 40 Nagasaki-sized atomic bombs.

    In principle, using the Atomic Energy Control Board's (AECB) regulatory limits, we can calculate that 0.1 micrograms of plutonium can overdose one person while noting that maximum safe exposure limits is placed at 0.56 micrograms maximum full body exposure and 0.25 micrograms for lung exposure. "Experiments with beagle dogs suggest that about 27 millionths of a gram of insoluble plutonium would be sufficient to cause lung cancer in an adult human being with virtual certainty, with significant risks probably associated with far lower doses," report International Physicians for the Prevention of Nuclear War.

    According to the Canadian Coalition for Nuclear Responsibility (CCNR) 0.1 grams would overdose one million people, one gram, ten million people, 100 grams, one billion people and 600 grams, six billion people.

      This expose says that Canada is transporting MOX fuel from the US and Russia. In addition,

      " Atomic Energy of Canada Limited has admitted, in documents submitted to Transport Canada, that in four out of eight categories of serious road transportation accidents, the MOX containers would be completely destroyed and a plume of plutonium dust would be spread downwind to a distance of about 80 kilometers.

      "Transport Canada has stated — not once, but several times, in its response to public commentaries about AECL's plans for MOX transport by road — that transporting MOX by air is much more dangerous than doing it by road because of the health dangers of inhaling plutonium dust following an accident…."

    Would these figures help in determining the measurement used in the Berkeley article? Also note that the measurements below are Only from Fukushima Daichi. They do not include radiation released from the 14 reactors in severe condition.

    In April/2011 …850,000 terabecquerels of radiation was released…(One terabecquerel is a trillion becquerels, the standard measure of radiation.) And the contaminated water at Fukushima I Nuke Plant contains 720,000 terabecquerels of radioactive iodine and cesium.

    The Nuclear and Industrial Safety Agency (NISA) on June 6 revised the level of radioactivity of materials emitted from the crisis hit Fukushima No. 1 Nuclear Power Plant from 370,000 terabecquerels to 850,000 terabecquerels.

    The NSC calculated the amount of radioactive materials released into the air between the outset of the crisis and April 5, based on the amount of radiation from measurements taken near the plant. NISA based its calculations on the state of the plant's reactors.

    Then prove that 14 reactors have been damaged, before I go any further, I am with you not against you.
    In my humble mind to prove this would be the end of nuclear reactors world wide, it means they do not meet their design perimeters and therefore they must cease operation immediately, as per directive from governing body.
    You should focus your attention on matters like this instead of rehashing the same old thing time after time, we know it is spewing vast amounts of radiation into the environment and their is nothing to be done about it apart from making sure it does not happen again and try to inform, especially the people of Japan.
    Now get cracking,
    the egg is dying
    no time for crying,

    • 14 reactors damaged on 311… probably more would be my guess. Especially since over 50 went into shutdown and they never really came back up.

      “Other reactors are all in considerably severe condition”
      — 14 total; Dai-ni, Onagawa, Tokai

      • weeman

        You would think that the engineers in Japan would be on top of this, no more in news since?.
        I know tepco is up to every trick in the book, it is like the manhattan project not one person has enough information to see the whole picture and therefore can not put it together but their is always a weak link, keep prodding you never know what you can accomplish.

        • MaidenHeaven MaidenHeaven

          Weeman I included it in my above post hoping someone could help calculate the amounts. And adding more *old details is meant to add information to those new to the site or just beginning to understand what is really going on.

          I know for myself it was reading the comments here & learning of *old details shared that helped me to understand the depth of the situation.

          I at least hope that if we keep making a point of mentioning that 14 reactors are in severe condition more frequently it will help shut all reactors down… So we need to keep on telling & commenting to get the info out. Not one person I have ever spoken to knows that fact or the other details we learn here.

          ChasAha I agree that there are probably more than the 14 damaged. It doesn't make sense they would shut any undamaged reactors down. And we never get the full truth from any agency so we know there has to be more to the story.

          • weeman

            One other avenue that I feel should be focused on.
            We have full audio recordings of the melt downs etc?
            No one seems to be looking at these and tying to reverse engineering them to figure out the chain of events and implications.
            The Achilles heal of reactors will be found and may have far reaching consequences.
            There is people on this site who have access to the equipment required and the education to analyze.
            Does that not make sense?

            • MaidenHeaven MaidenHeaven

              Hardy full recordings unfortunately weeman…in bits & pieces …Tepco having withheld most even from the agency looking into the accident. I do see your point but with so much withheld we instead are trying to pick apart what we d have….& in the end..earthquakes I/we can still come to the same conclusion…the Reactors are not able to withstand earthquakes…noting that I am including the incidents in the USA as well. Whether they *caused actual damage to the reactor or not is even secondary (of course still important)…they each directly affected the power sources to the reactors.

    Forgive me if I'm wrong but isn't this….extremely very very bad news? Plutonium is 100% lethal isn't it?

      Yes, and now, we have introduced the never before seen plutonium buckey ball.. this allowed that plutonium to travel to the USA, especially the West coast, and this is why the cow farmer in Southern Cali had weapons grade plutonium on his fresh cow pies..
