462 trillion Bq of Strontium leaked to the ocean, Fukushima Diary, December 19, 2011 [Emphasis Added]:

  • Asahi newspaper […] tried to estimate the total amount of leakage of strontium
  • They are based on the Tepco’s press release
  • [For some reason] they assumed it only leaked from reactor 2 in April and from reactor 3 in May
  • Also, they ignored the strontium from the fall-out as well
  • Even Asahi newspaper warns about the biological concentration in the sea

Strontium, spill into the sea trillion becquerels 462, Asahi, Dec. 18, 2011:

TEPCO’s Fukushima Daiichi nuclear power plant after the accident, the released amount of radioactive strontium in the ocean, the Asahi Shimbun found that estimates be at least about 462 trillion becquerels. Fisheries Agency is considering the strengthening of research examining the accumulation of fish and shellfish samples.

Calculation was performed based on data released by TEPCO, etc.. Unit 2 in April, for radioactive contaminated water spilled from No. 3 in May […]

The amount drops to the ocean from the atmosphere is not included. […]

Strontium is not easily excreted and accumulate in the bone, it is that there is cause bone cancer and leukemia, it has been pointed out the need for further investigation.

Professor, Tohoku University Graduate School of Agriculture geological history of Katayama (Resource Ecology and Fisheries), according to the need to pay special attention to accumulation in the bone, such as whole food Kounago and Silas. “Strontium tends to accumulate in organisms at low concentrations. We need detailed investigation,” he said. […]

Earlier this month, it is thought that over 5 trillion becquerels of strontium was contained in the 45 metric tons of contaminated water that leaked from an apparatus at Fukushima: 5.8 trillion becquerels of strontium leaked from Fukushima over weekend

    Ancient Acidic Ocean a Killer:The great die off 250 million years ago may have been due to a change in the pH level of the oceans:

    Scientist creates new hypothesis on ocean acidification:

    “…A recent reanalysis conducted by Dr. Paul Jokiel from the Hawai‘i Institute of Marine Biology (HIMB), suggests that the primary effect of ocean acidification on coral growth is to interfere with the transfer of hydrogen ions between the water column and the coral tissue. Jokiel re-evaluated the relevant data in order to synthesize some of the conflicting results from previous ocean acidification studies. As a result, Jokiel came up with the “proton flux hypothesis” which offers an explanation for the reduction in calcification of corals caused by ocean acidification…”

    (It would seem likely that ionizing radiation would also interfere with this exchange..and contributing to the reduction in calcification, no?)

      Autoradiagraphs and x-radiographs have been made of vertical sections through the centers of reef corals from Eniwetok. Radioactivity bands in the coral structure are caused by strontium-90 and are related to specific series of nuclear tests, thus making possible calculation of long-term growth rates. These data indicate that the cyclic variations in radial density revealed by x-radiography are annual.”

    and the IAEA said

    IAEA to coordinate Pacific monitoring
    14 December 2011

    “It is expected that the enormous dilution capacity of the Pacific Ocean will lead to low residual concentrations of radionuclides in ocean waters such that any significant contamination of marine food in coastal waters outside of Japan will not occur,” said IAEA technical officer Hartmut Nies. “To date, only caesium -134 and caesium -137 were detected far offshore from the Japanese coast in the prevailing Kuroshio Ocean current at levels of less concern.”

    The first meeting for the project took place in Australia in August, while a training workshop was held in the IAEA Environmental Laboratories in Monaco from 21-25 November. The workshop led to the adoption of a quality management system and database for the future monitoring efforts. The project is expected to run till 2015, with a first progress report due in 2012.”

    Excessive radiation found in sea organisms off China
    Updated: 2011-08-24 21:12

    “According to the statement, the levels of strontium-90, a radioactive isotope of strontium, found in squids are 29 times higher than the average background level of samples taken from China’s coastal waters.

    This indicates that these waters have been clearly affected by radioactive material that leaked from the crippled nuclear power plant in Fukushima during the massive earthquake and tsunami disaster on March 11, the statement said.

    The samples were also found to contain argentum-110m and cesium-134, which are normally difficult to detect in biological samples from China’s coastal waters, the statement said.”

    china more truthful than the IAEA?? arent china a member of the IAEA?
    WHAT HAPPENED TO THE TESTING DONE BY THE CHINESE IN NOVEMBER? has the IAEA done a deal with the chinese?? …..

      THis is most likely not from Fukushima but from Chinese nuclear wastes and dumping. No country in the world has such disregard for the environment and people’s safety than China so one should think twice before blaming fukushima for everything. Very little fallouts from fukushima have gone towards western Japan let alone China…

    A gazzilion babillion, shmamillion… come on…. the numbers are seeming to get so big as to create cognitive dissonance. We need some one to put this into relative terms. When does TEPCO become not fiscally bankrupt, but morally so? If there are world war crimes… shouldn’t there be some body out there that goes…” Heh… you freaking broke your country… now get out of the way”.
    I am over the fear porn.. and now just fascinated at the myriad of idiot news articles, shows, columns that talk about the most trivial minutia… while totally ignoring this AND for all rights and intents… BP Spill as well. Out of site out of mind? I own four geiger counters. They are all professional grade, but getting them was difficult and expensive. I have them outside in lead lined PVC tubing…with battery powered UPS systems hooked up to the geigers, the wifi system, the router, computer, monitor etc. I have had many days of high spikes… my system is impeccable… and if I talk about the results must people think I am a nut job or worse! I have 4 retail businesses and a small restaurant. Three great kids and a great wife. What’s more…I am HAPPY. I am not one of those people that hopes the world is coming to an end so I won’t have to balance my check book. but….<462 trillion becquerels of strontium> what the heck is that number even relative to…how do we digest it? Is it that if it gets so big…we mentally feint? Let’s do something about this. K.

    • I think people on this site and some others would welcome your readings, and ‘spikes’ that you are measuring. Maybe a dose of reality would wake up more people.

      Have you started a video channel yet? Take a video of what you are measuring, with what instruments, on what day, location, time, etc.

      A Bq is a disintegration per second. A disintegration is matter becoming somewhat less matter and releasing a high energy particle, be it Alpha, Beta, Gamma or whatnot. Each one of these high energy particles could ping into a part of your body, a cell, a bit of DNA and do damage. Strontium is a bone seeker, it acts like calcium and once it goes into your bones it doesn’t leave. So it get down close to where you manufacture blood cells in the bone, and the bone itself and starts blasting away.

      So just in that one release, TEPCO released enough strontium so that every human could have 60,000 disintegrations PER SECOND going off in their bones. Now, this strontium will also go into animals, corals, and maybe some just to the bottom of the sea where it will just be blasting away at nothing that important.

      Now the good part it that this “pollution” doesn’t last forever, Strontium 90 half life is around 30 years, so in 30 years, the number of disintegrations per second blasting away at your bone and blood production will be down to 30,000 PER SECOND. Or roughly 108,000,000 PER HOUR. That doesn’t sound all that great does it?

      But this would be a pretty high level of contaminantion, 60,000 per second (at the start) divided by an assumed body mass of 220 lbs, or 100 kG is 600 Bq/kG which is the commonly stated way to measure it in food stuffs.

      Above 500 Bq/kG in rice, and they shouldn’t sell the rice anymore unless they can sneak it into a children’s school lunch, and force them to gargle with some radioactive tea [this is actually happening right now].

      But to be fair to the pro-nuclear pimps who keep insisting that coal will kill us unless we embrace nuclear, what they often measure in food is the Cesium, and they ignore the strontium because Strontium is the Bogie-man, the monster under the bed, and they don’t want to talk about the monster under the bed, they don’t want to scare the sheeple.

      Cesium has a biological half…

      • stock

        Cesium has a biological half-life of around 90 days, that means your body eliminates it through fluids and feces, so it doesn’t damage you as long. So it is only hitting your cells with 108,000,000 high energy particle AN HOUR for only 90 days, and then at 90 days, it has reduced to 54,000,000 high energy particles AN HOUR blasting away at your innards, your cell, muscles, DNA, reproductive organs. Got it? Got some perspective now?

        I was born in 1963, I probably have 50 times the normal level of Strontium in my teeth (and thus my bones). 1963 was the worst year for nuclear testing of bombs. That sucks.

        Strontium was found in Hilo milk in 2011. The Canadian “limit” for Strontium in milk is 30 Bq/kG.

        They found 1.4 pCi/l, and then they stopped testing

        No one uses the same units of measure leading to some of the Cog Dis you spoke of. And the FDA and EPA have widely varying standards, with the FDA ALWAYS allowing way more radiation in your food. Note also that the EPA stated that they didn’t find any Strontium 90, only the relatively safer Strontium 89. Note what they didn’t say…they didn’t say they testing for Strontium 90 and found none, just that they found none. No tin foil hat needed to figure that one out. Strontium 90 and 89 will be formed at the same time in fission processes, they will both be present, and the 90 will last longer.
        From Forbes

        To wrap your head around that, the FDA allows 4400 pCi per kilogram for Strontium 90, or using this calculator
        around 162 Bq/kG, most other countries allow 20 or 30 Bq/kG in food products for Strontium 90. Lets say you drank 1 gallon per week, or about 3 kG, and that…

        • stock

          Lets say you drank 1 gallon per week, or about 3 kG, and that… 80% of that bio-accumulated in your body, and the dose rate from 162 BqkG, That would be 388 Bq per week, or 20,200 Bq accumulated in a year. 20,200 dis-integrations per second, or 72,000,000 cell blasts per hour, or 637 Billion cell blasts per year.

          NOW getting back to “perspective” there are 50 to 75 trillion cells in a human body, or 50,000 to 75,000 Billion cells, and only 637 Billion “cell hits” are being delivered, or only one out of 100 cells are being hit. EXCEPT

          The Strontium locks into your bone structure, so it keeps hitting the cells right around it, maybe picking on 8 or 10 nearby cells (just guessing). So lets say your City said to you that only 1 out of 100 people were getting mugged per year, however the mugger lived on your floor of your apartment and the mugger only mugged people on that floor and you were one of them and you got mugged once a week…well that is what your cells feel like. “They” don’t like to talk about the Bogeyman. Japan allows 35 Bq Strontium 90 per kG of fish.

          So keep smiling, and you will feel great between the muggings. Stop nuclear, it is too powerful for humans, stop abusing atoms, it will end our species. How embarrassing would that be for the huge black-hole category mass of the Egos of nuclear scientists who can’t resist playing with their toys.

            Back in the 1960s the youth counter-culture were well aware of the hazards of Strontium 90. I remember snippets of a song from that (weapons testing) era.

            “… fallout will get you, even under ground.
            So if you want some Strontium, Strontium 90
            There’s plenty enough to go around.”

            Somehow that edgy awareness turned into apathy or acceptance over the years.

            I notice there is now a band called Strontium 90.
            They have song titles such as “Every Little Thing She Does is Magic” and “Lady of Delights”.

            It feels as though the “bad guys” have managed to commoditize Strontium 90 over the years.

            Such processes are ongoing, and they make “bad” become “normal” over time. Then a new generation discovers that “bad” is “bad” after all, and the cycle begins again.

            Strontium 90 and vertebrates cannot coexist. Fortunately, vertebrates have backbones. No nukes!

            Dear stock,
            just replying to your comment about some of the ionizing radiation falling to the seafloor where it will blast away at nothing really that important…even there (and maybe especially there) in the depths of the oceans ecosystem (and by extension, the entire earth’s ecosystem), the balance of alkalinity and acidity matter greatly and effect what happens in the rest of the ocean:


            “…Most species possess at least some buffer molecules. Fish and other active species stockpile them to reduce temporary pH declines that result from extended swimming bursts. Just like in a runner, muscles shift to anaerobic (nonoxygen based) metabolism during sprints, which uses up ATP (the main fuel molecule) more quickly, causing extra H+ ions to accumulate. But few species can stockpile enough buffering to last across extended timescales. If small pH changes occurred gradually over tens of thousands of years, a species might evolve adaptations, for example, by retaining chance genetic mutations that result in greater production of buffer molecules. But species generally cannot adapt to changes occurring over mere hundreds of years or less. Similar changes produced in the lab over days to weeks are lethal.

            In past eras when CO2 concentrations rose, species with less well-buffered systems fared poorly. Declines in pH may especially harm deep-sea species, whose stable environment leaves them ill equipped to adapt to change. (For this reason, proposed strategies to combat climate change by pumping large quantities of CO2 into the deep sea are worrisome; they could destabilize the habitats of a wide array of creatures.)…”

    • aigeezer aigeezer

      Yes, the numbers we get are numbing. It can’t be an accident that “they” keep switching terms with every report (can it?)

      Assuming that “they” are unlikely to provide standardized measurements so that “we” can make meaningful interpretations, it may be best to just master the terminology and be ready for whatever they throw out.

      Here’s a starting point (mainly the box in the upper right area) that may also give you a chuckle in these difficult times:

  • Children used to play in the sand boxes and streets around Chernobyl. They no longer do. The streets are quiet.

    Let’s apply the theory of dividing and counting the total amount of sand grains in a sandbox, by using a thimble.

    Surely, if we only count the grains of sand in a thimble, in one corner of the sandbox, and then report back how few sand grains there are in one tiny corner, no one will notice that, will they?

    Of course the job is to count all of the grains of sand in the sandbox, but there is way too much sand, so what to do?

    If people TRULY KNEW the horrible TOTAL amount of radiation that has left these reactors, and what is still coming out, it would spell the doom of not just nuclear power, but quite literally, many future millions, possibly billions of lives. Genocide ever so sweet, ever so invisible, yet ever so horrible in its certainty of outcome, some years down the road.

    Genocide is too horrible to even contemplate, so the ‘experts’ continue to count thimble fulls of sand grains, and dole these official’counts’ out on a bi monthly basis, pretending as if the sandbox has no sand left in it.

    Meanwhile the waterfalls of invisible doom continue to flow down the rivers, into the ocean, the mother of all life. The poison seeps into her heart, slowly, efficiently, quietly, invisibly.

    Rivers of invisibly poisoned air flow with the wind currents and sweetly caress the faces and freshly cleaned hair of children with a dark, hollow, empty meaning, devoid of all soul and minus all love.

    The children no longer play in the sandboxes… they no longer run and play in the streets. So sad, so quiet, so painfully quiet… ah, the children, the children, the children.

    Meanwhile, the experts continue to count thimble fulls of sand.

      “In a very small area, less than 10,000 square miles, we have counted more than 100 fountains, or torch-like structures, bubbling through the water column and injected directly into the atmosphere from the seabed,” Semiletov said. “We carried out checks at about 115 stationary points and discovered methane fields of a fantastic scale — I think on a scale not seen before. Some plumes were a kilometer or more wide and the emissions went directly into the atmosphere — the concentration was a hundred times higher than normal.”

      Shock as retreat of Arctic sea ice releases deadly greenhouse gas

      “…Scientists estimate that there are hundreds of millions of tonnes of methane gas locked away beneath the Arctic permafrost, which extends from the mainland into the seabed of the relatively shallow sea of the East Siberian Arctic Shelf. One of the greatest fears is that with the disappearance of the Arctic sea-ice in summer, and rapidly rising temperatures across the entire region, which are already melting the Siberian permafrost, the trapped methane could be suddenly released into the atmosphere leading to rapid and severe climate change.

      “Dr Semiletov’s team published a study in 2010 estimating that the methane emissions from this region were about eight million tonnes a year, but the latest expedition suggests this is a significant underestimate of the phenomenon….

    I’ve been a professional scientist for a while now. Here is what I have learned.
    The media, TEPCO, and various other “agencies” try to “blind the public with science” using indigestible terms, numbers, and explanations. They lie constantly by misinterpretations, withholding information, and scare tactics.
    Is there anyone here that believes anything TEPCO says? What the media reports?
    Listen, these numbers are meaningless to the majority of our brothers and sisters.
    stock@hawaii does an exceptional job in this discussion.
    Here is the bottom line. When reactor 3 experienced the nuclear explosion and scattered the contents of the reactor and spent fuel pool into the environment, all numbers essentially went to infinity. This continued release cannot be stopped. This is an extinction-level event.

First, what an amazing site, thankyou so much for keeping us current despite the near-blackout and ‘inaccuracies’ in our media (I’m on the US arc of the great Pacific bowl). Next, thankyou to people like anne and whoopie and so very many of you who share your citizen expertise.

    Last, hats off to stock and kauai for comments in this thread. Kauai, well put! and i do hope you’ll share your readings here or elsewhere, we need *someone* to be doing it! Btw, i don’t know if this has already been mentioned here, but you all might be interested in this info about US’s token monitoring system, RADNET (this report says it’s run by a private contractor, from a little abandoned-looking bldg in New Mexico)

    Stock, wow, way to spell it out, doing the math and explaining it re: trillions of Bq blown/leaked/emitted from Fukushima. That’s what got me to register here, to say well done and thanks.

    Just the other day, talking economics, a friend did a great visual explanation of ‘illions’: if you made a stack of dollar bills, with a thousand of them, then make a thousand of those stacks, you’d be looking at a million dollars. if you pushed all of those dollars together into one big pile, and then made a thousand of *those* piles, you’d be looking at a billion dollars. then, if you push all those piles together into one giant pile of a billion dollars, and then make a thousand of *those* piles, that would be a trillion. etc for quadrillion, petaBq, whatever.

    Anyway, thanks and hello to all!

  • Pallas89juno Pallas89juno

    I haven’t read the other posts today. Forgive me if someone has already mentioned this. Once again, we have an analysis of one of hundreds or thousands of radionuclides that are out there from the ongoing absolutely uncontrolled fissioning at, at least, Fukushima Dai Ichi–not controlled by TEPCO with water as is implied on the Thom Hartmann Show, repeatedly in every broadcast. These figures above, which look probably fairly close to being right–remember fro Srontium only, are only some tiny fraction of all the radionuclides that are being continuously emitted from Fukushima. The emissions are effectively continuous and are daily.

  • When Japan says FUKU is in cold shutdown, most people ASSUME that the crisis is over, everything is buttoned down and done. No more radiation, ever.

    Sadly, this is NOT the fact. As Dr Awesome and another poster pointed out above, there are a number of reactors that have melted down, melted through and/or exploded. These are ALL RELEASING RADIATION DAILY. Then we have spent fuel pools that are also releasing radiation in various amounts.

    ALL OF THE ABOVE ARE RELEASING TOXIC RADIATION DAILY, despite their claims of ‘cold shutdown’.

    The company does not even know for sure where the melted out of control 65 ton radioactive corium blobs from some of these reactors are, much less what they are doing. They have the GALL to say ‘cold shutdown’. They are measuring where the fuel USED TO BE, inside of an empty reactor vessel, with nothing left inside of it, because all of the corium leaked out.

    What the company is doing and the media is letting them get away with (conspiracy anyone?) is like Joe Blow setting a huge forest fire, which travels SOUTH with the wind. The fire department comes and sprays the non burning forest across the street going in the opposite direction (NORTH) of the fire and says the fire is out. They never even bother to LOOK FOR THE FOREST FIRE, much less try to put it out. That is roughly what the company is saying and doing about these out of control radioactive fires.

    Correct me if I am mistaken….
