Sci. Technol., 2011, 45 (23), pp 9931–9935, Publication Date (Web): October 20, 2011 (Emphasis Added):

Introduction

  • Interestingly, the concentrations through the end of July remain higher than expected implying continued releases from the reactors or other contaminated sources, such as groundwater or coastal sediments
  • By July, levels of 137Cs are still more than 10 000 times higher than levels measured in 2010 in the coastal waters off Japan
  • [Regarding] radioactive discharges directly to the sea [...] some was unconstrained and likely resulted from contaminated groundwater discharges

Continued Release

  • The break in slope in early May implies that a steady, albeit lower, source of 137Cs continues to discharge to the oceans at least through the end of July
  • With reports of highly contaminated cooling waters at the NPPs and complete melt through of at least one of the reactors, this is not surprising
  • This change in slope of 137Cs in early May is clear evidence that the Dai-ichi NPPs remain a significant source of contamination to the coastal waters off Japan
  • There is currently no data that allow us to distinguish between several possible sources of continued releases, but these most likely include some combination of:
  1. Direct releases from the reactors
  2. [Direct releases from] storage tanks
  3. Indirect releases from groundwater beneath the reactors or coastal sediments

Delayed Release into Ocean

  • The levels at the discharge point are exceedingly high, with a peak 137Cs 68 million Bq m3 on April 6
  • What are significant are not just the elevated concentrations, but the timing of peak release approximately one month after to the earthquake
  • This delayed release is presumably due to:
  1. Complicated pattern of discharge of seawater and fresh water used to cool the reactors
  2. Interactions with groundwater
  3. Intentional and unintentional releases of mixed radioactive material from the reactor facility

    So this is going to be a continuous, massive contamination of the ocean, affecting world food resources. Time to wake up and take decisive action against this criminal nuclear mafia!
    People of the world, get simple Geigers, check the food everywhere and demand the producers recall any contaminated products. Authorities want you to trust them, they don’t want people to go around supermarkets taking readings. If you do it, food industry and retail trade will feel the threat to their money-pocket and may understand that it is time to turn against nuclear industry.

      The gig counter does not help with particle contamination.
      Gigs pick up gamma. LIke an xray. Dispersed particles like beta and alpha don’t show much of gamma reading. BUt if you ingest a few particles here and couple more there, then these beasties go to town on cell destruction. THe lungs, the human filter liver. Everybodies liver is so overworked already and couple brothers of cesium can realy turn up the heat.

        I understand a simple Geiger counter can’t pick up much of the alpha and beta that are so harmful when ingested. But I just thought that we ought to be seen to distrust authorities on this matter, raise public awareness about the danger in the food we’re eating and the lax controls, and simply annoy the industry by taking things in our own hands and checking food directly on the market. If you cannot afford a Geiger, you might even hold out a fake device or your cell phone!
        This might start a trend of concerned consumers. Right now, most people would simply be too shy to dare question the safety of goods displayed in stores!
        However, this is just a sudden idea, and before rushing to implementation, it would probably be wise to find out what sort of prosecution you may face, as there probably exists some law against “unnecessarily raising public anxiety” or “disrupting lawful business activity” or something like that …

        • Yes of course if you can measure everything an afford a professional device, that’s perfect, but the professional instruments get really expensive.
          Its important check food even with not so high tech instruments. And CS137 for example emits a lot of gamma (also beta). If contaminated by fall outs usually you get a mix of particles.
          If you can afford a GM lots of have mica windows for alpha particles also (and beta of course).

      TEPCO: Radioactive water may have leaked into sea

      The operator of the Fukushima Daiichi nuclear plant says radioactive water leaked from a water treatment facility may have reached the sea through a gutter.

      Tokyo Electric Power Company says slightly elevated levels of cesium were detected on Sunday in seawater around an outlet from the gutter.

      Earlier in the day, workers found that at least 45 tons of water had leaked from a desalinization device at the plant. The water then apparently seeped out of the building and flowed into the gutter.

      The leaked water also contained radioactive strontium at levels that could pose health risks in case of internal exposure. TEPCO says it will take about 2 weeks to complete its analysis …

    Now, everyone says that when this molten mass of hotties, hits water, it is supposed to do a little boom boom action.
    Is the reaction hitting water level, causing the heated water to go the path of least resistence and vent into the ocean? Or maybe they already had wells designed, in place, to vent off steam near every reactor?
    Lots of steam poring out of this, no. May not be just from the top.

    • it is near water all the time. all the explosion stuff is only to lame attention because it will never happen while the silent poisoning could go on (as everybody is waiting for an explosion for months)
      maybe the cores are empty since the buildings explosions and everything (distributing nuclids) that could happen already happened.
      Tepco is doin really nothing to stop any form of leakage and the rest of the things they do is just cosmetic.
      a lot of press conferences

      and they have a prepared story just in case it does a fission explosion

    I don’t think this is corium in the groundwater. I remember reading several weeks ago (it would take me time to dig it up) that TEPCO was walking a tightrope on water removal from the basement. If they took out too much, ground water seeped into the basement, filling it back up and making more water to decontaminate. If they took out too little, it seeped from the basement into the ground water, contaminating the upper water table and ocean. So odds are that it seeped out for months, releasing radiation into the Pacific, before they discovered the need to carefully balance the removal (which happened only after they removed enough to discover this seepage), taking out only as much as they pumped into the reactors.

      They’re talking about cutting down the forests since they acted like big filters during the initial blow-offs and caught lots of particles. As it rains, those are rinsed out and sent downstream and into those rivers. I’m sure both the cooling attempts and beginnings of groundwater contact have a role to play, but add in the rinse from the mountain forests as a source as well. And perhaps the idiotic burnings of contaminated materials.

      China Sends Ship Again to Study Ocean Contamination off Fukushima
      “Beijing, Nov. 29 (Jiji Press)–A Chinese survey ship left Tsingtao, Shandong Province, on Monday for the western Pacific to investigate radioactive contamination of the ocean following the nuclear accident at Tokyo Electric Power Co.’s <9501> Fukushima No. 1 plant.
      According to a Web site run by China’s State Oceanic Administration, the ship and its crew of about 30 will spend 35 days at sea covering some 9,260 kilometers.
      This is the second such survey carried out by China in the wake of the March 11 accident. The first ship was at sea from June 16 to July 4.
      Following the initial survey, the Chinese government said it had detected radioactive substances such as strontium-90 in seawater samples and firefly squid taken in waters off Fukushima Prefecture.”

      The Japan Coast Guard said the Chinese ship was spotted 330 kilometers off Japan’s northeast coast where the crippled Fukushima nuclear plant has been leaking radiation into the air, soil and sea.
      Japan said China should have asked for permission as the vessel was sailing inside its 200-nautical-mile exclusive economic zone (EEZ).

        First 330km offshore is international water. Second, if the Japanese weren’t lying through their teeth and throwing everything they can into the ocean, then the Chinese probably wouldn’t have a desire to be doing the research and finally I don’t think the Japanese are in much of a position to put many demands on other countries right now.

I have concluded that this is never accidental when it happens. I watched the hard drive light working away furiously but could not use the mouse or keyboard to get out of that loop. Only 312 people, but all are probably well documented. When I rebooted, Firefox did not ask me if I wished to return to the page I was on when my PC shut down.

    Japan’s growing problem of radioactive water – to be dumped into ocean?
    by Christina MacPherson

    “‘We have stored processed water in tanks, which are expected to become full by March next year,’ said a TEPCO spokesman on Thursday. He said no final details – such as when, how much, or how dirty the water would be – have been established, but stressed the water would be filtered to reduce levels of radioactivity before it was dumped.

    Thousands of tonnes of water have been pumped into reactors at Fukushima in an effort to cool the molten nuclear fuel and bring the plant to a safe shutdown.

    ‘We are studying a variety of measures to cope with it,’ he said, including the possibility of building more storage tanks. ’The company has consulted with the Japan Fisheries (JF) Cooperatives about the possibility of a water release.’ A group of fishermen immediately lodged a protest with TEPCO and the Economy, Trade and Industry Ministry on Thursday, demanding the plan be shelved…..”
