A mind-boggling 40,000 trillion becquerels of radioactive cesium, or twice the amount previously thought, may have spewed from the crippled Fukushima No. 1 nuclear power plant after the March 11 disaster, scientists say.

Michio Aoyama, a senior researcher at the Meteorological Research Institute, released the finding at a scientific symposium in Tsukuba, Ibaraki Prefecture, on Feb. 28.

The figure, which represents about 20 percent of the discharge during the 1986 Chernobyl nuclear disaster, is twice as large as previous estimates by research institutions both in Japan and overseas. […]

While the latest study said 15-20 quadrillion becquerels of cesium-137 was released into the atmosphere, the Japan Atomic Energy Agency estimated the amount at 8.8 quadrillion becquerels. […]

  • lam335 lam335

    And how exactly does this new estimate compare to Chernobyl???

    • Spectrometising

      Iam335,,,,,It exactly and very accurately compares to Chernobyl mind bogglingly.

      I thought it was an accurate description. At least someones mind boggled and not lobotomised. The average intelligence score on this subject is somewhere near a complete lobotomy.

      Here at Enenews, some like myself consider it a high attainment to merely be mind boggled.

    • lam335,
      It doesn't, Chernobyl was No more then a nuclear sneeze, …

      Compare to three plus world wide deadly pandemic radioactive virus's !

      To directly answer your question, Chernobyl released 79,500 TBq of Cesium 137.

      The definition of propoganda is saying something over and over again, often enough that people believe it, despite it being a total and complete fabrication.

      What is this number based on? How did they calculate it? What input did they put in the computer? Put garbage in, you get garbage coming out.

      I am absolutely amazed at how investigate journalists do not even ask ANY questions, or seek out ANY other opinions. The truth it seems, is something that is no longer something to seek out or report.

  • dear jones

    TEPCO and The Japanese Government will do their best to make sure the estimate is lower than Chernobyl !!!


    the article itself, goes on to say, "While the latest study said 15-20 quadrillion becquerels of cesium-137 was released into the atmosphere, the Japan Atomic Energy Agency estimated the amount at 8.8 quadrillion becquerels. Similar data released by other researchers both in Japan and overseas ranged between 7 quadrillion and 35 quadrillion becquerels."

    These numbers are…STAGGERING!

    BTW. The attempts to cover the sea bed with cement are not going smoothly. "Choppy waters due to adverse weather conditions had obstructed the work."

    Make sure you check the article out…

    • Spectrometising

      Covering the sea bed with concrete is the most silliest thing i have heard.
      Concrete is much heavier than water or sand on its own and will merely sink……….
      Then it will displace and disturb the settle materials………
      Then particles will be mobilised again…
      I have worked on many a building site and understand the dynamics.
      On this i am an expert !!!!
      When pouring concrete into mud……………
      The mud rises to the top………..
      Concrete is very heavy……………..


        @Spectrometising: I agree. Such efforts are insane. Their effort lends new meaning to 'sweeping it under the carpet'. If it wasn't so sad, I'd be laughing right now…

      • CaptD CaptD

        I thought they were using clay not concrete on the seafloor!

      • Anthony Anthony

        Hmmm with that in mind… wonder if the nonsensical concrete ocean bed is actually to DISPOSE OF radioactive sludge? I can see them doing that.

      from this

      "Regarding the radioactive noble gas Xenon‐133, the results indicate an emission of 16700 Peta‐Becquerel (1 Becquerel is one radioactive decay per second, 1 Peta‐Becquerel equals 1015 Bq). This is the largest civilian noble gas release in history, exceeding the Chernobyl noble gas release by a factor of 2.5|"

      and this

      "Regarding Cesium‐137, which is of high relevance for human health due to its physical properties and the long half‐life time of 30 years, the new estimate shows that emissions started earlier and ended later than assumed in most studies so far. The total release amounts to 36 PBq, which equals 40% of the Chernobyl emissions. About 20% of the caesium was deposited on Japanese territory, while about 80% was deposited in the water."

      an interesting question here

      "Is anyone else curious why the Xenon-133 release from Fukushima is 250% higher than Chernobyl, yet the Cesium-137 release from Chernobyl is 250% higher than Fukushima?"

      heres the norwegian cover up report! by the more private mysterious and corporate NILU


      In the American system, the Latin prefix refers to the number of groups of three zeros, not including the last group of three, which represents a thousand. Thus in the USA, a billion is 1,000,000,000 (10E+9) and a quadrillion is a mere 1,000,000,000,000,000. (10E+15).
      In the British system, which is in use in the rest of the world, the Latin prefix represents the power of a million, thus a British billion is 1,000,000,000,000 (10E+12) and a British quadrillion is 1,000,000,000,000,000,000,000,000 (10E+24).


      all those ZEROES!! anybody make sense of the actual AMOUNTS involved?? 🙁

      • arclight arclight

        to confirm that the word quadrillion is ineffective in international use as it can be massively taken out of context…

    I getting confused. Daichi is number II right? So Number I is spewing cesium.

  • Alice Alice

    When the radioactive release has more zeros than the U.S. National deficit, Houston, we have a mighty huge problem.

      Buckyballs (Buckminsterfullerene) is a "new" form of carbon molecule
      Note that the Uranium variant of Buckminsterfullerene is a very new phenomena that as far as I know is as recent as (and directly the result of) Fukushima. It came about from the use of the salt water to cool the spent fuel and reactors/cores. The direct contact of the salt water on the Uranium was the problem. Fukushima is probably the first time that such a combination has happened to the extent that the result was measured/measurable.

    Fukushima is ten time worse than Chernobyl said Former minister Kan. But "The figure, which represents about 20 percent of the discharge during the 1986 Chernobyl nuclear disaster" BULLSHIT

  • dosdos dosdos

    Fukushima released a relatively small amount of cesium compared to other isotopes. Chernobyl released a relatively large amount of cesium compared to other isotopes. If you look only at the cesium figures, Chernobyl was worse. and this is the figure that the press is keying on to call Fukushima the second worst nuclear release in history.

    It is the xenon, strontium, and iodine release that makes Fukushima the worst release in history, not the cesium. However, because xenon and iodine are so short lived, and because strontium is so costly to detect effectively and positively, they were able to cover up those figures in the media.

    So cesium is the news, because it looks better to be less than Chernobyl somewhere.

    • maaa

      Chernobyl = 1 reactor blowing up. Fukushima = 4 reactors. And you really believe the cesium levels are lower? C'mon where's your common sense.

  • Laterlukemayb Laterlukemayb

    Okay, they keep talking about Cesium, what I want to know is where does plutonium fit in this picture. Is plutonium a constant, does it degrade or is a completely different creature all together?

    Chernobyl at Ten

    "’I have seen the beginning of the end of the world,’ is how Michael Mariotte, editor of The Nuclear Monitor, put it after visiting Chernobyl's doomed landscape, everything dead or dying for miles around. ‘The end of the world begins in Pripyat, Ukraine, a once-thriving city of 45,000. Now it sits crumbling, abandoned, a mute but overwhelming testament to technological arrogance gone amok.’[1]…
    “Cancers and other disease caused by Chernobyl's radioactive poisons are being recorded thousands of kilometers from the reactor site. The ninety million people who lived in the path of the very worst fallout are learning the hard way that damage done by ionizing radiation is unrelenting, cumulative and irreversible….
    “Cesium-137 contamination is probably Chernobyl's most devastating and ominous consequence. The body can't distinguish cesium from potassium, so it's taken up by our cells and becomes an internal source of radiation. Cesium-137 is a gamma emitter and its half-life of 30 years means that it stays in the soil, to concentrate in the food chain, for over 300 years. While iodine-131 remains radioactive for six weeks, cesium-137 stays in the body for decades, concentrating in muscle where it irradiates muscle cells and nearby organs.[16]
    “Strontium-90 is also long-lived and, because it resembles calcium, is permanently incorporated into bone tissue where it may lead to leukemia.
    “The Soviets acknowledged in 1986 that the influence of cesium-137 on cancer death rates would be nine times that of iodine-131. They said that the effects of strontium-90 would ‘perhaps have, along with cesium-137, the most important meaning.’[17]

    “Exposure to radiation more often results in genetic and reproductive damage than cancer. These hereditary disorders are unlimited in time, since they pass from generation to generation in the sperm and ovum.

    • Dr. Anne Lee Tomlinson Maziar anne

      So, as geneticist Soyfer points out, Chernobyl's enduring biological legacy will be that of inherited diseases, deformities, developmental abnormalities, spontaneous abortions and premature births….
      “In a long page one story, the Aug. 2, 1995 New York Times reported that life expectancy has plummeted in Russia, making it the first nation in history to ever experience such a public health status reversal. Male life expectancy is now the lowest in the world (below even India or Bolivia) and, at the same time, infant mortality rose 15 percent in both 1993 and 1994, and there are now epidemic rates of heart disease and cancer…

      “What everyone does know about nuclear reactors is that they have a record of whole-earth poisoning, and that their potential for more of the same is considered acceptable — authorized in advance. This potential, for unlimited and uncontrollable radiation "accidents," has been deliberately developed, promoted, protected, ignored and then denied, or forgotten….”

    Contaminants Released, Chernobyl

    “A retrospective view of the Chernobyl accident of Apr 26, 1986 assesses the total radiation release at about 100 megaCuries or 4 x 1018 becquerels, including some 2.5 MCi of cesium-137. The cesium is the most serious release in terms of long term consequences. The total release was around 4% of the total accumulated activity of the core and compares to a release of 15 Ci at Three Mile Island. The release was then about 7 million times that at TMI. Anspaugh, et al. suggest that essentially all the noble gases and about half of the volatile elements (iodine-131, cesium-134 and cesium-137) were released. The cesium release from all of the atmospheric weapons tests is estimated to be about 30 MCi. The noble gas releases were estimated by Levi to be 45 MCi of xenon-133 and 5 MCi of krypton-85. About 3-5% of the core inventory of the relatively refractory elements such a strontium, plutonium, and ruthenium were released, much more than from a light water reactor meltdown.”

    • Dr. Anne Lee Tomlinson Maziar anne

      TYPO: 4 x 10^18 becquerels, including some 2.5 MCi of cesium-137.

      • Dr. Anne Lee Tomlinson Maziar anne

        So Cesium-137 released by Chernobyl was 10^17 becquerels. This is 2,500 times more than the Cesium-137 so far released by Fukushima Daiichi if the figure of 40,000 trillion becquerels estimated Cesium-137 released by Fukushima Daiichi so far is a good estimate.

  • PhilipUpNorth philipupnorth

    We need to put in cheap residential wind and solar power, and solar domestic hot water, with fuel cell backup. Disconnect from our homes the tainted nuke power from utilities. Tell the utilities we won't patronise them because they insist on nukes. Fight them in our local area. Fight them nationally. Stop poisoning our planet!


      @philipupnorth: what you suggest is noble but inefficient. You have to take such steps on a mass scale, to be truly effective. There are billions who depend on electric energy sources. Replacing nuclear power in a hodgepodge manner will take just as many decades as was used to put nuclear power in place. This must be done on a large scale, with the assistance of all concerned parties. We're taking a resurgence of jobs on a scale unknown since the great wars. We're taking massive investments in R&D, into the development of long-term-survivable renewable energy systems. It would be a golden age for all of us…

      • PhilipUpNorth philipupnorth

        Quite correct, Aftershock. Last I heard, the economy needed to be re-energized. Millions of jobs. Distributed power, Bloom Boxes at every office, factory, and mall. Wind and solar everywhere. Payoff would be free fuel, in sunshine and wind. Make it cheap, put it everywhere. Install current technology now, with R&D bringing prices down later. New tax incentives needed. Community involvement. Decades of economic prosperity. Decommission all atomic plants now. This, too, will add millions of new jobs. Golden Age for all.

    These are very desperate times for Japan and now for the rest of the world.

    It will be very hard to determine the truth from any source in the future.

    We are in a place where modern mankind has never been before and I am afraid this disaster and certain types of nuclear radiation contamination will last from many thousands of years on the surface of our Mother Earth.

    Best not to speak very loudly about these pending world holocaust matters around any of our children, sshhh..

    Silently weep for all of our futures and all the other life forms on our Mother Earth.

    But only weep once the children are tucked into their beds and they have fallen into a deep sleep.

  • howardtlewisiii

    Keep trying to dodge it and get GE and the government into answering for their sins. I quit building this crap back in 1975 and they should have also. We all knew about spent fuel needs demineralized water changes to be stored, for thousands of years and more. Breeder reactor programs worsen the containment problems. Take suppliments and if others lack the attantion span, sit on them if they are family and let them go if they want. Cancers are brewing.
