Upsurge of iodine-131 in Japan. Daiichi on fire?

The latest analyses of sewage sludge in Gunma and Chiba prefectures shows that iodine-131 levels have sharply increased in the last two months. The presence of this short-lived radionuclide indicates criticalities have been occurring at Fukushima Daiichi. It is also the cause of thyroid cancer, thyroid nodules, and other thyroid diseases.

The Gunma graph indicated the highest amounts of I-131 found since testing began in May 2011. The peak in early June is slightly higher than the previous peak in May 2012. Note that levels dipped in early July and bounced back up again in mid-July. This suggest that two separate criticality events have occurred.

The Chiba graph shows a similar situation, with a June peak which was high, but lower than the short sharp spike in September 2012. Chiba also dipped and then rose again in late July, similar to Gunma.

The wind directions have something to do with I-131 contamination in sludge, as do rainfall amounts. Chiba is to the south of Daiichi, and Gunma is to the west. But they agree with each other, pretty much.

The secondary peak in late July indicates a radioactive plume has been emitted, which has already arrived in the US. I expect it to reach the east coast in a couple of days. Certainly there have been radiation spikes in Japan recently. There were many hospitalizations after a heavy rainstorm occurred during an outdoor concert in Tokyo.

A Japanese blog post (here and here) has been making the rounds of message boards and twitter, alleging that a fire has occurred at Fukushima Daiichi. The area circled in red is the water injection crane. Certainly there have been large amounts of steam and smoke at the plant recently. And you don’t necessarily have to have flames to have a fire in nuclear fuel.

The situation is as bad or worse now as at any time since the initial catastrophe in March 2011.

    • I get Chiba here:

      I take the highest values on the list for each time period.

      The links I had for several other Japanese localities have gone away, or moved. These two prefectures are the only ones that still work for me.

      I don’t know why they still publish the incriminating data. Maybe the prefectural governments are less monolithic than, say, the USA. Certainly there is a lot more information available about radiation in Japan than the US, which has next to none. And there is a lot more free discussion, and interest in radioactive contamination, there.

  1. The site believed to be on fire is the location of the new big light, which appears to turn off.

    I do strongly believe that all hell is breaking loose there, as evidenced by spiking rads and huge, unusual steam events.

    I am fearful.

    • I’m still recovering from the last criticality. The iodine caused symptoms of thyroid rage, which is very unpleasant.

      This is secondary hyperthyroidism, driven from the pituitary. Most people get hypothyroid symptoms, rather than hyperthyroid, but both were elevated at Chernobyl.

      Damage to the pituitary affects the thyroid, and the thyroid affects the pituitary too. We’re going to see a lot of osteoporosis among younger adults who are ordinarily not at risk for this bone disease.

  2. TEPCO withheld groundwater information from NRA officials in meeting

    On Monday morning this week TEPCO officials were meeting with experts from Japan’s Nuclear Regulation Authority to discuss ways to mitigate and approach the nuclear disaster at Fukushima Daiichi. During the meeting, TEPCO officials failed to notify the regulatory body of rises in the groundwater levels at Fukushima Daiichi, even though the data they had showed that groundwater levels had risen 2.5 meters above an agreed upon benchmark.

    Tokyo Electric’s failure to report the rising groundwater levels frustrated NRA Chairman Shunichi Tanaka, who told reporters, “TEPCO has no sense of crisis at all.”

    Tepco is building the impervious wall on the coastal line, but since they started the construction, the groundwater level is rising…

    1. Impervious wall is not stopping sea contamination…
    2. Contaminated groundwater may be spreading to other areas of the plant…
    3. The east side of reactor2 is becoming literally “swamped”.

    The impervious wall Tepco is building to stop contamination of the Pacific is being overtopped. And it is causing groundwater to rise and spread to other areas of the plant. This groundwater will weaken the foundations of the reactor buildings, and they may collapse, causing a catastrophic radiation release. Also, the groundwater itself acts as a medium to slow neutrons down, and is increasing the frequency and intensity of criticalities.

    Tepco has no sense of crisis, and their incompetent actions are risking the entire planet.

    • EDITORIAL: Incompetent TEPCO should never be allowed to handle nuclear energy

      Has Tokyo Electric Power Co. learned nothing over the past two years and four months since the nuclear disaster started at the Fukushima No. 1 power plant?

      We cannot help but ask this question in light of the utility’s appallingly shoddy handling of radioactive water that is leaking from the crippled plant into the sea. We must also note that the Nuclear Regulation Authority and the Agency for Natural Resources and Energy of the Ministry of Economy, Trade and Industry, which are responsible for overseeing TEPCO’s operations, can hardly be said to be living up to their responsibilities.

      All sorts of stories and editorials in mainstream media now. No response from the White House or the gangsters of the IAEA.

  3. Iodine-131 in sludge in Kunimi, Fukushima prefecture has also been sharply increasing through June:

    Prefecture north Purification Center located at the Fukushima prefecture Date–gun Kunimi town to the 19th in July is Fukushima prefecture sewer endings treatment plant radioactive substance concentration monitoring result of is were presented. The According to its article, Iodine-131 is 924 Bq / kg from sludge was collected on 8 June use are detected. This value is 794 Bq / kg of the 12th January was a maximum value this year has exceeded the. Iodine-131 is not detected much until February to May, but the detected value is increasing rapidly to become a June. June January source (H25.1.1 ~ H25.6.30) North County Purification Center (Japanese)

    • Units 5 and 6 are now involved in strontium-90 release:

      Strontium first detection Daiichi Units 5 and 6 at the port outside

       The 31st, TEPCO announced strontium has been detected 5.8 becquerels per liter of seawater from the harbor outside the Fukushima Daiichi Units 5 and 6 the discharge canal. The presence of underground water pollution of the sea side campus is found in June, and later to strengthen the monitoring of seawater, strontium be detected from seawater of the nuclear power plant outside the harbor for the first time. (Japanese)

      • A meltdown at Unit 5 would explain the cobalt-60 readings found a while ago. Co-60 is generated from the interaction of neutrons with building materials. It would not be expected to be generated from the underground coriums. It would also explain the iodine-131 activity.

        • Bobby1, could you please do a very short separate thread on the possibility that reactors 5 and 6 are melting down?

          I’ll post it where I can. I have been posting the link to this comment at enenews, and so far not a single response. It is the first post on a thread that has 900+ views, yet not a single response! No one cares?

          Very Breakfast of Champions.

          Here’s what PattieB said about Reactor 5 today:

          the number 5 reactor lost control rods… self-started with lid off it.. is why they called manufacture in to get lid on expanded top.. and it has MASSIVE FISSURE right UNDER IT !!

          not much word on 6… semi-stable..?

          • NoNukes, I will consider it, but it’s only speculation at this point. But the notion of #5 or #6 melting down does fit the data. But there are so many other areas that are steaming, spent fuel pools, or the remains of them, various tanks, pipes, hoses, that it is awfully hard to know.

            Hi Majia.. Never seen them do that before. They panned left and zoomed in on units 5 and 6 and did it quickly on demand. Then they Zoomed in up close for about thirty seconds. Could not believe my eyes. Was clear as it gets. Just started focusing my eyes to look for trouble spots. Positive that I saw a squareshaped cover over the unit 5 on the far left side, same kind as unit one has over it. You know that big white roof vented building cover like on unit one. It also appeared to be the source of the heat waves we see on TBS cam. Cannot say for sure on that cuz as I was trying to identify the source more closely the camera then panned back to 1 thru 4 and again Zoomed in clear as day on unit three, the smoldering pot, for about thirty seconds. Hope someone here knows someone that was recording what I saw. Very intriguing indeed. So nothing on youtube. Surely others saw what I’m talking about…

            I recall about a year ago the same thing happened and at that time some people who saw it claimed it looked like fire at unit 5.

            I don’t know.

            Entire plant a disaster beyond imagination.


              • Yes, that’s what I was looking for, the timing. This apparently has nothing to do with groundwater levels rising at the plant from the wall construction… this happened before that started.

                • Yes, all that talk about Tepco in the MSM is BS cover, as usual.

                  Posted a string of info on the webcam page. So happy that someone is reading, thanks for your link below.

                  We are going camping in the aerosolized plutonium. Have a good weekend. 🙂

  4. TEPCO Proves Again, They Can’t Be Trusted To Operate A Nuclear Reactor
    July 25, 2013
    “Workers at Fukushima Daiichi lost cooling to unit 6 for 2 hours today. They were performing a test for an emergency diesel generator when they turned off a power panel. This caused the reactor to lose cooling for 2 hours. This is a highly abnormal situation where they lost both power sources resulting in a loss of cooling for such an extended period of time. The long time frame indicates there may have been equipment damage TEPCO is not disclosing.”
