87,100 Bq/Kg from sewage sludge in Fukushima / 3,800 Bq/Kg from Tokyo sewage sludge

On 5/20/2014, Ministry of Land, Infrastructure, Transport and Tourism published a report about radioactive contamination of sewage sludge.

The samples were collected from April to May of 2014.

Even though it has been over 3 years, the report shows high level of Cesium-134/137 is still measured in the sludge taken from Fukushima city.

The highest reading was 87,100 Bq/Kg. Cs-134 density was 24,500 Bq/Kg, Cs-137 density was 62,600 Bq/Kg.

Also, 3,800 Bq/Kg of Cs-134/137 was measured from the sewage sludge collected in Edogawa ward Tokyo. This is 38 times much as food safety limit in Japan.

Le 20 mai 2014, Le ministère de la Terre, des Infrastructures, du Transport et du Tourisme publiait un rapport sur la contamination radioactive des boues des caniveaux.

Les échantillonnages se sont étalés d’avril à mai 2014.
Le rapport montre qu’on relève toujours une très forte radioactivité en césium 134/137 dans les boues de la commune de Fukushima, même si ça remonte à plus de 3 ans.
Le record a été de 87 100 Bq/kg. La radioactivité du Cs 134 était de 24 500 Bq/kg, celle du Cs 137 de 62 600 Bq/kg.

En outre, ils ont relevé 3 800 Bq/kg de Cs 134/137 dans des boues de caniveaux du quartier d’Edogawa dans Tokyo.
C’est 38 fois la limite alimentaire japonaise.

  1. Because you are an engineer, Iori San, it would be good if you could explain how this sludge is being contaminated. Are we dealing with human excretion? Runoff from pavement after rain? What is the source?

  2. Reminds me of an old post.

    Quote of POPS @ October 28, 2011 at 12:48 pm:

    “Once upon a time, the Tokyo Bay (Edo Bay) provided the Tokyo people (Edo people) with lots of good, fresh and cheap fish. It was why the Japanese sushi (Edomae sushi) was created in Tokyo (Edo) during the Tokugawa shogunate. The Tokyo Bay doesn’t produce fresh fish today but, at least, the legacy of Edomae sushi remained until today. But, in the near future, the Edomae sushi will become a complete history.
    The ancient Edo city also boasted one million residents since the 17th century because it could host that large population thanks to the summer breeze from the Bay which gently cooled the burning hot city. Not to mention the rich fishery resource of the Bay.”
    …
    “Once the Bay is contaminated by the dumping of radioactive wastes, the bay breeze from the Tokyo Bay will get contaminated soon or later as well.”

    That bay breeze seems important in understanding possible atmospheric contamination. Sounds like it could host salt spray from the bay.

    Small puzzle pieces.

  3. Quote of Mochizuki: “In this discussion, the fact that two sludge disposal facilities workers died all of a sudden only in two weeks in October was leaked by a worker at a sewage farm in Chiba.

    No further information was added, but sewage sludge is known to be very radioactive.

    Because it is too high to deal with normally, Japanese government gave up controlling it.

    Radioactive waste which is lower than 8,000 Bq/Kg is treated as normal garbage.

    Chiba is one of the worst hot “prefectures”.

    It is easy to assume the sludge disposal facilities were severely contaminated.

    However, none of the related news has been reported, we didn’t even know the situation is so serious.

    We hope more workers leak honest info by taking advantage of any chance.”

    http //fukushima-diary.com/2011/10/two-sludge-disposal-facilities-workers-had-sudden-death-within-2-weeks/

    . . . . . . . .

    Two more dead workers not on any official list, presumably from radioisotopic contamination, including other toxins, as internal radioactive contamination acts as a toxicity multiplier.
    Jimmy Conca said nobody died. What have i counted so far; Seven, isn’t it?

  4. I think if the workers were eating sewage sludge the cesium would be the least of their worries.

    Oh dud, you’re so funny.

    1. “According to the data, only the “minor part” of the ash contains 1,525 ~ 12,390 Bq/Kg of cesium-134, -137 on the daily basis. (page 2)

      It’s from our everyday garbage.

      Refuse incineration ash is separated into the major part and the minor part.
      The later one is the dust trapped in the filter.
      This is the data of the minor part.
      About the major part, the data is blank for some reason.”

      HP is noted near the top of every pages text, so that may not be the same Prefecture.
      However; it does highlight that there are additional pathways to contamination for those workers.
      Also, how hot does it get in summer in Chiba? Does it have a cool breeze like Tokyo?

      Perhaps a primer on mentality of company at time is in order.

      “Tepco is planning is sprinkle “low” level contaminated water in the area of the Fukushima plants.

      They stocked 17,000 tons of contaminated water in the tanks.

      It came from the reactor 5 and 6.

      They explain they will not be harmful for the environment because they will purify it with zeolite.

      Cesium is supposed to be less than 0.05 Bq/cm3 (50,000,000 Bq/m3), which is the safety limit of bathing beach,though they do not mention other types of the radioactive material such as strontium etc..

      Tepco is planning to sprinkle it after receiving permission from the local citizens.

      They are trying to stop wood from sparking (ed: what does THAT look like), and also stop dust flying.

      Also,they are intending to make the tanks empty by doing it.”

      1. Those two workers likely labored through the summer heat and september rain.

        Quote: “The shortest day is 11:48 long and the longest day is 12:55 long with an average length of 12:21.
        Afternoons can be hot with average high temperatures reaching 26.1 °C (79 °F).
        The weather in September is very slightly soggy. Around 177.4mm (7in) of water is unloaded.
        Overnight temperatures are generally warm with an average low of 19.7 °C (67.5 °F).
        The mean temperature in Chiba is really warm at 22.6 °C (72.68 °F). ”

        Does anyone have a link to historical weather data for Chiba in 2011?

  5. BILL! Have you seen Ontological’s Cesium Sky pics?
    Jaw, meet floor. Nice historical comparisons, though few.

    1. Ahh, enenews. The only source more reliable and trustworthy than fukushima-diary.

      1. He’s not enenews, rather an independant AFAIK.

        That’s the best you have to say, after practically screaming that Pink Sky was impossible at Mr. Duff? Maybe we could agree that so far it is inconclusive until verified.

        Am not here to change your mind. Who knows? If some semblance of conversation is begun, what we find together may change both minds somewhat.

        1. Fuck inconclusive. It’s flat out retarded. Conversation is impossible with those who want to believe. Its like trying to discuss religion with jehovas witnesses. Pointless, because they believe first, then find supportive evidence for that belief. That their supportive evidence is thin, and common sense overwhelmingly obvious, always escapes them, because they have their thin supportive evidence so they must be right. It’s completely stupid, and the very same thing occurs every day on this blog, usually accompanied by mutated links to some fringe supportive ‘evidence’. Bears rolling down hills, the mystery glowing fuel rod pic, footballer with a scar on his head, people on twitter complaining about headaches… meanwhile the overwhelmingly obvious common sense is entirely absent. We could replace nuclear power entirely if we could only harness and convert Internet Stupidity to electricity,

          1. Did you have to do “inconclusive” Doggy Style?
            I converse with topic “Pink Sky”, and you respond with “retarded” “religion”. Am i simply supposed to “believe” you? If it is supposedly “common sense overwhelmingly obvious”, do enlighten us peons that are not so.
            Ah, so you have finally lifted your pork-fried fingers to briefly crow about the glowing mass @ NorthWall of Eunuch #4.

            Niall’s argument ran down hill, went stiff-legged, rolled over & died like bear. Let us weep for pathetic attempts at distractions from what appears to becoming common knowledge.

            1. Do note that an absense of evidence does not equate to evidence of absence. I hate to say this. You’ve earned it though, once again.

              FAIL from Sweden! “All aboard the FAIL boat!” “Toot! Toot! \\\\\\BOOM/////”

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
