Japan TV: Extremely high radiation at Unit 1 raises concerns about how Tepco will decommission reactor — Workers were to be in area with 1,000 millisieverts per hour for ‘clean-up’ (VIDEO)

Highest radiation found at Fukushima No.1 reactor

The highest level of radiation to date has been detected inside the No.1 reactor vessel at the Fukushima Daiichi nuclear power plant. 

[...]

The utility detected a record level of 10,300 millisieverts per hour. The measurement was taken 20 centimeters above the surface of a contaminated water puddle in the reactor’s suppression chamber.

[...]

1,000 millisieverts per hour was detected about 4 meters above the water surface.

[...]

Workers are expected to engage in clean-up and other tasks mostly at the 4-meter level, which is raising health concerns.

TEPCO official Junichi Matsumoto said he suspects that a higher radiation level in the No. 1 reactor is caused by more fuel rods melting down than in other reactors.

    How did Tom Waits put it? "And the earth died screaming", I believe it was.

    The manual laborers at Fukushima Dai-Ichi are indeed martyrs of some order or another.

    Please post articles with these dose rates in the full sievert scale. There is no need to assist the media in whitewashing the facts here…

    However, I'd love to see the banana comparison at this rate…
    Or even the chest X-ray placebo…

    ;)

      TG

      a banana is 0.1 uSV so at the 4 Meter level at 10,000 mSV/hour its effectively 100,000 Bananas per hour.

      now the average banana weights 120 grams, lets call it 100 grams to make it simpler and acccount for the peel,,,,

      So we are talking 10 metric tons of banana consumption per hour.

      Now as a volume it's about 500 Grams/liter for a banana so we are talking 5000 liters/ hour or
      about 1000 gallons per hour of bananas

      to give the reader a visceral feel, that's about 3 gas trucks per day or a swimming pool per week.

    If I can speak for Tepgov for a moment "We will do it with technology yet to be invented."

  • Radiation levels inside Fukushima reactor 1 are equivelant to being force feed bananas while being X-rayed to death…

    Stay calm, tepco is investing in the technology to rectify the situation; which should be readily available by 2050. In the mean time come visit the beautiful beaches of fukushima… Where extream tanning takes a whole new meaning…

    Too soon?

      But no one asks them into what the "cold shut down"did mutate, no one from the optimistic docile journalists flock. They did not even ask what part of this monstrous radiation escapes day by day.

  • It bothers me that they are still saying "decommission reactor". There IS no reactor. It is a pile of rubble.

    I suspect the word decommission is used to make it sound like everything is hunky dory.

  • Wasn't 10 sieverts the threshold for radiation detection?…

    Convert millisievert (mSv) to sievert (Sv)
    10,000 millisieverts: is equal to 10 sieverts

      Yes TG, good memory. Last time TEPCO had a spot that hot they called it "off scale". Unless there has been an equipment upgrade, it may well be hotter than they can even measure.

        But then again, perhaps if the figures look too bad, the use equipment that can't measure more than a certain level. Maybe they had the gear to measure higher all along, but choose not to use it.

    "TEPCO official Junichi Matsumoto said he suspects that a higher radiation level in the No. 1 reactor is caused by more fuel rods melting down than in other reactors."- Or just the opposite – some molten mass still lingering behind? Remember, they could not find the fuel in R2 with the endoscope…May be some day they will declare coriums a property of Hades realm, like they did with golf players.

      rac 1 was the smallest, it could be it didn't burn it's way out of the bottom but stayed in the basement. Rac 2/3 being bigger probably burned their way out.

    Oh well. As long as the clean-up takes place its all good, since the sites does not clean itself magically.

    They are not going to be able to decommission reactor 1 they will have to entomb till technology caches up in two or three thousand years at best estimate.

    Decommissioning means that all fuel is removed, all pipes, pumps and systems are flushed until releasable and the entire building under the limits of a radiation and contamination zones. It means you could walk in the area without protective equipment, without dosimeters and be able to eat off the floors.

    I agree weeman, 2000-3000 years is a good estimate.

    This is most likely about the conservation of promoting nuclear energy, george bush, elizabeth of england and the others amongst the toilet trash of our "trustworthy government" BUUUUUUUURRRPPPP!
    have stock in this horrid power.
    These volatile blurbs pop up when convenient according to the "leaks" of information that is needed to explain away.
    Staying in game with the topic, the #1 reactor is a distraction from what is happening in #4 notice when what is said about 2and 3 not as radioactive, no mention of 4.
    This disaster appears to be out of the scope of practice for anyone.

    " Fukushima nuclear power plant

     TEPCO 27, was announced in the basement reactor building of Unit 1 of Fukushima Daiichi Nuclear Power Station, in the building and was measured 10,300 milli-sievert per hour…"

    10K ++ millies per hr. Yape!

    Chances are this reading is nothing compared to what the readings were just above the reactors in the beginning according to this article http://enenews.com/nhk-3-75-sieverts-per-hour-was-detected-far-above-reactor-3-by-helicopters-dumping-water-on-mar-16
