According to Fukushima prefectural government, high level of Iodine-131 was measured from sewage sludge (Dry state) this June.

The sludge was collected in the Northern part of Fukushima prefecture.

 

Their data shows I-131 started being detected on 6/12/2014. It kept being detectable since then and it reached the peak on 6/14/2014. The reading was 1,017.2 Bq/Kg.

It was still 800 Bq/kg the next day.

I-131 density went in the decreasing trend after the peak, but it kept on being detected until the end of June. The data of July hasn’t been published.

 

I-131 can be detected when it’s used for medical treatment, and also nuclear fission occurred in Fukushima nuclear plant.

 

It could have been from the medical usage, however it can be unlikely to have increased gradually.

 

Cs-134/137 has been continuously detected from the beginning of this year.

 

Tepco has made no announcement about this I-131 measurement.

Plus de 1 000 Bq/kg d’iode 131 dans des boues d’égouts du nord de la préfecture de Fukushima

Selon la préfecture de Fukushima, en juin dernier une forte radioactivité en iode 131 a été relevée dans des boues d’égouts (sèches).
La boue provient du nord de la préfecture de Fukushima.

Leurs données montrent que la détection d’iode 131 a commencé le 12 juin 2014. C’est resté détectable depuis et le record s’en est établi le 14 juin. Ce record est de 1 017,2 Bq/kg. On était toujours à 800 Bq/kg le lendemain.
La radioactivité en I-131 a commencé à diminuer après ce pic mais elle est restée détectable jusqu’à la fin juin. Il n’y a pas eu publication des données de juillet.

L’iode 131 peut être détecté lorsqu’il a été employé par des traitements médicaux et après qu’une fission nucléaire ait eu lieu dans la centrale nucléaire de Fukushima. Si c’était d’origine médicale alors il serait peu probable d’assister à une augmentation graduelle.
Du césium 134/137 a continuellement été relevé depuis le début de cette année.

Tepco n’a fait aucun communiqué sur ce relevé d’iode 131.

Vous pouvez lire ceci parce que nous avons survécu jusqu’à aujourd’hui.

  1. http ://interactive.snm.org/index.cfm?PageID=11031

    Someone ingested I-131 as part of radio iodine treatment and was excreting it into the sewers for a week. Happens all the time.

  2. The indicated RadioIodine values appear consistent with medical use release; and FAR below Fukushima levels measured in March 2011 – April 2011, in the USA, 6,000 miles away.

  3. If memory serves,

    About twice that I-131, value was measured on California Strawberries in Spring 2011.

    No, I did not eat any fresh strawberries, mushrooms or fresh cheese after March 17, 2011. But stocked up until then, allowing for Fukushima Travel time by Jet Stream.

    1. Your memory, as always, fails you Bill.

      http ://radwatch.berkeley.edu/FoodChain#strawberries

        1. Oh please Bill. Provide us with a link to a measurement of these imaginary 1000 Bq/kg California strawberries. lol.

          1. GFY,

            Who would be stupid enough to eat mushrooms and strawberries, DOWNWIND of an ongoing nuclear disaster?

            Who would willingly eat seafood; which lives downstream from an ongoing nuclear accident?

          2. The statement was ‘ON’ strawberries, NOT ‘in’ strawberries.

            Please feel free to GFY, asshat.

        1. Berkeley WHO?

          Didn’t Bill Wattenburg attend there, or something.
          I cannot profess to remember.

          To think, i was going to support them for free. Ppah;!!

      1. UC Berkeley is unfortunately not a particularly reliable source.

        Doctor whatshisface Muller once, (about a year after 311) screeched in the WSJ, that Fukushima Reactors had passed the test.

        Also, who was the LOSER that was experimenting with Plutonium medical experiments on retards and blacks? Wasn’t he from UCB? If memory serves that same loser then certified that Guam was ‘clean as a whistle’.

        Team Nuke has been lying through their teeth for about 75 years now.

  4. So, nobody counts 129I, which may have exceeded 131I releases?

    It’s the ratio that’s telling, iirc. A “baseline” 129I would be indicative of RAI, neh?

    Patients do not excrete it all at once, iirc. Also a percentage of that 131I excreted in sweat.

    What role do Johkasou play in Fukushima Prefecture now, and how does that civil infrastructure relate to these measurements in sewage sludge?

    Teach us, please Iori-san.
    My humble and sober respect for all thyroid patients in any Prefecture.

    1. The ACTIVITY of I-129 is low, relative to I-131. So a gram of I-129 release is medically and environmentally a lot less to worry about than a gram of I-131.

      With a 15 Million Year Half Life, the I-129 increase could be charted, but not so definitively tied to a particular radiological event; such as the FDNPS meltdowns.

  5. Also, i see that 131I, and also 129I accumulate in the pituitary gland, liver, kidneys & bladder, as well as the thyroid. Humble and sober respect to those patients too.

    Storm drainage and flush toilet sewage systems are somewhat seperated in Tokyo Prefecture. Are these measurements from a combined system?

  6. No Prussian Blue 4U …

    ‘Local gov’ts give iodine tablets to residents as reactor restart looms’ KAGOSHIMA, Japan, July 27 – (Kyodo), http ://english.kyodonews.jp/news/2014/07/304036.html

    Local governments started Sunday handing out iodine tablets to residents living within 5 kilometers of an offline nuclear power plant in Kagoshima Prefecture, southwestern Japan, that may restart in the fall. It is the first time iodine tablets have been distributed under Nuclear Regulation Authority guidelines instituted following the 2011 Fukushima nuclear disaster. Iodine tablets help protect thyroids from radiation.

    Heart Attacks and Congestive Heart Failure, from RadioCesium will be ignored; or perhaps encouraged.

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.
