Radiation rises sharply in Fukushima Unit 3 — “It appears the concern was due to increasing levels in the area” (VIDEOS)

Published: November 28th, 2012 at 12:00 pm ET



Radiation levels in Fukushima Daiichi Reactor 3 more than doubled in many locations since measured last year

TEPCO announced that the robot used to enter the Fukushima Daiichi Unit 3 Reactor Building measured radiation levels up to 4,780 mSv per hour, nearly three times the 1,300 mSv reading taking in the same location last year on November 14th, 2011. […]


[…] TEPCO did not state the nature of the inspection other than to look at the gas duct hose. It appears the concern was due to increasing radiation levels in the area. TEPCO was likely inspecting the duct as the source of the possible increase. No leaks or damage were found on the duct.

What they found was that the containment door and track were the source of the increased radiation levels. […]

The first graphic [on right] is the levels for the containment hatch and rail. Levels from 2011 are included to compare to the new levels showing the increase.

    Radiation levels going up, rather than going down.

  • They have a 'concern'.

    "…radiation levels up to 4,780 mSv per hour, nearly three times the 1,300 mSv reading taking in the same location last year on November 14th, 2011"

    Maybe that's why they were spraying stuff on the side of R3.
    The urgency at which these guys move is obvious.

      According to NRC http://www.nrc.gov/reading-rm/basic-ref/glossary/lethal-dose-ld.html the LD50/30 (commonly called "lethal dose", but means there's 50% chance of surviving the first 30 days given best treatment money can buy) is 4 to 5 sieverts. This is quite much in agreement with other sources. The speed at which a dose is received matters a lot, of course, so that level can be considered "lethal in one hour". Even before that the recipient of such high radiation could become disoriented and unable to get out of the radiation on their own.

    Decommissioning will take 40years, draft considered to get workers???

    "If this health management problem is underestimated, workers may start avoiding the work at Fukushima I Nuclear Power Plant, causing the delay in decommissioning which is estimated to last for more than 40 years.

    40 years. That's why some right-wing politicians (including the vice governor of Tokyo) have been talking about reinstating the draft and send young people to work at the plant, willing or not.

      "…reinstating the draft and send young people to work at the plant, willing or not."

      Good plan. Take the best and brightest of Japan's youth and send them to their death.

      It will keep them from rioting like the youth in Europe when they all realize their economic future is non-existent, stolen from them by their politicians and business leaders, abandoned to die by self-induced nuclear winter.

      Good luck.

        They can then thank their government that has lied to them for the last year and a half. The same government that they loved so much in the past…

    • patb2009

      Japan already has a low birth rate, sending in young people to get cancer, radiation mutagenisis
      and heart disease will just make it worse.

      if they draft workers, draft in the elderly.

      • MaidenHeaven MaidenHeaven

        Quite correct Pat. In 2006, Japan reached a demographic and social turning point. According to Tokyo’s official statistics, deaths that year very slightly outnumbered births.

        Japan is now a “net mortality society.” Death rates today are routinely higher than birthrates, and the imbalance is growing. The nation is set to commence a prolonged period of depopulation. Within just a few decades, the number of people living in Japan will likely decline 20 percent. The Germans, who saw their numbers drop by an estimated 700,000 in just the years from 2002 to 2009, have a term for this new
        phenomenon: schrumpfende Gesellschaft, or “shrinking society.”


        • MaidenHeaven MaidenHeaven

          This report does not include the deaths that will & have occurred as result of Fukushima & the continued evacuation of young people & families.

  • Time Is Short Time Is Short

    For some perspective:

    The Bank Of Japan, their version of the US Federal Reserve, just reported an operating loss of ¥183.4 billion yen, and a net loss of ¥232.9 billion yen, with a total outstanding national debt of ¥156 trillion yen:


    In a country where there are more adult diapers sold than baby diapers:


    The funding to clean up Fukushima does not exist domestically.

    With every other country broke, no one is rushing to provide Japan with the trillions of USD that would be required to meet even minimum thresholds of nuclear containment. Not to mention that no amount of money on this planet will provide for the hundreds of thousands of semi-skilled workers required for a project of this magnitude.

    All that is left is more lies, until there's no one left to lie to.

      Or completely overcome the money paradigm concerning the
      reactor accident due to its nature as a global emergency.

  • gr81 gr81

    Just keep those incinerators at maximum fire and SMILE.

    The rest of the planet has far too many ideologically and greed motivated wars (death tolls being a measurement of campaign success) and outright thievery to be concerned about the future, especially those pesky kids!

    If memory serves, wasn't this door the source of high rads from the last test done a year ago? The thinking was that the explosion threw radioactive debris against the door which also set it ajar. But, why is it higher now? Nearly 4 times higher? I recall that getting an actual measurement last year was next to impossible given the robots were malfunctioning in the high radiation. So, the figure of 1,300 mSv may be completely unreliable. Anyone know? They worked to get the door to close and decided to wait a year and see if the levels dropped. Either the levels rose or they became more accurate. If the case is that they rose, then, it is possible the increase is simply due to the area now being better enclosed and the heavier radiation having no where to go so it builds. I also don't see which specific radioisotopes are higher. This looks like a simple total radiation level measurement. Knowing what radiation is actually higher – is this plutonium, cesium, etc.? – and in what ratios would go a long way toward explaining why. What this may be evidence of is whether a hydrogen or a plutonium detonation took place in Reactor 3.

    More good news. Is a splatter of corium wedged into a crevice? Hard to say what is causing this incredible rise in radiation but corium would be my major suspect.

  • moonshellblue moonshellblue

    Hmm 'the containment door and the track' according to Tepco are the sources of the high levels. I imagine that a meldown of tons of core melting rapidly at unbelievable temperatures would splatter instead of the simulations showing what a core meltdown would look like, (youtube) that slow drip drip but of course we're talking huge drips, which I'm sure they can determine by taking the circumference of the holes in the bottom, but I certainly am not a nuclear engineer and math was never my forte. Rambling….

    • Radio VicFromOregon

      moonshellblue, the corium could certainly be cause for the high readings, though, i would expect them to be significantly higher than what these most recent tests show if it is corium that has somehow NOT melted down out of the reactor and into the ground below, which should lower the readings in the above ground area. Are you thinking that the corium, or some of it, stayed above ground in the reactor room? That's a thought, too. Or, the theory Arnie put forward of a mox fuel explosion. In that case, there'd be corium below ground and mox fuel pellets above ground along with that splatter of corium? along the door and edge that may have escaped the same route the pellets took, perhaps the jarred reactor lid. It wouldn't take much of either to cause these readings. It'd be nice for us not to have to guess and that a panel of knowledgable nuclear physicists and engineers could sit down and rationally discuss this without an agenda or a need to prove the safety OR the dangers of nuclear energy. Just the facts. They will speak for themselves. I'm not completely sure that even scientists at the NRC are having candid brainstorming sessions among themselves away from the commissioners' eyes and ears, though i would hope they were, if just for curiosity sake. Too bad TEPCO refused the help of all those retired professionals. I think their appeal is still at the UN. Anyone know?

    CTBTO data shows daily releases of iodine, barium & tellurium.
    Tuesday, November 27, 2012
    CTBTO isotope measurement station at Takasaki, Japan (Japanese) is indicating radioactive iodine-131, barium-140 and tellurium-132 was being detected every day from Oct.1 – Oct.31. Previous reports (link here) show that officially, iodine has not been detected since July 2011, barium since May 2011, and tellurium since April 2011. Of course, iodine-131 has regularly been showing up in sewage sludge, as reported here and at Fukushima Diary. And Mochizuki is reporting that radioactivity in seawater has been increasing from early September to mid-October.
    Tellurium-132 is produced by criticalities. It was the first isotope detected after the Japan earthquake, and it indicated that a meltdown was occurring. It decays into iodine-132. It is currently appearing at mid-April 2011 levels.
    Barium-140 is a dangerous isotope. Its presence always means strontium-90 is also present, because both isotopes are released by the same physical process. It is being released at …”

    We know they admit to chicanery in the placement and setup of Tepco monitoring posts:

    "TEPCO made a document for public release on April 20, 2012 explaining that they have “improved” the area surrounding monitoring posts by cutting trees within 20 to 30m, replacing soil and placing shielding walls, so that readings remain below 10uSv/h. It details the case of 8 monitoring posts, and they cite an example where the radiation dose went down from 83.6uSv to 9.7uSv."


  • rakingmuck

    As we all know there is no level of "safe" radiation. Still a background level in the US is considered normal withing a range of 10-60. http://radiationnetwork.com/index.htm I have been following this map for year. I am seeing more cities popping up above 50 – closing in on 60 every day. Be prepared. Not nearly the level of Fukushima but highly dangerous.

    • Radio VicFromOregon

      Rackingmuck, thanks for the heads up. Two sources of the higher readings comes to mind for me: 1) rain from the Pacific will bring Fukushima radiation to the ground and water, and 2) underground radon. Radon seems to increase during the rainy season perhaps because the rising water table forces it up? While it is a naturally occurring radiation, no one should get too much of it or too close. Definitely worse than the bananas PR campaigns are so fond of referring to. RadNet makes it clear that they can't distinguish types or sources of radiation, though i think they are working to be able to do that. Wouldn't it be nice to know how much of what kind of radiation? The difference is significant, especially in how to respond. If it's radon under my house, then i had better get it sealed under there or be forced to move. If it's various manmade radiation from Fukushima or nearby nuke plants, then i will want to increase my calcium/mag intake and add an additional drop of ionized iodine to 3 total drops in my morning cup of hot water. Maybe some additional Vit C and, some say, Vit D3. Still other good daily or emergency actions many of us can easily take in the enenews Methods for Combating Radiation Forum.

      • Radio VicFromOregon

        Oops, here's the link to make going to the forum even easier.


        Rackingmuck makes a good reminder for all of us to stay aware of the levels. We get so used to the high level of alarm that we forget to take what steps we can for ourselves and our friends and families. For those who will be getting heavy rains, this is when we especially have to pay attention and remember that radiation does not disperse evenly into the environment or fall evenly to the ground nor move evenly through the water. I can stand in a heavy rain, get soaked and not receive a single micro-sievert, while someone fifty feet from me can receive enough to cause illness in their future. Take what measures you can that cost very little.
