Translated by Fukushima Diary

Dust from a vent hole of a smoking area in Haga machi, Tochigi Prefecture. It’s been used as a storage room since 2011

  • Cesium-134 : 81,091.8 Becquerels per kilogram (Bq/kg)
  • Cesium-137 : 128,604.1 Bq/kg
  • Total: 209,695.9 Bq/kg

    Good report from Fukushima Diary…thanks Mochizuki!

    More information…Haga-machi is about 117 miles by land transport from the crippled nuclear plant and has 16,000 residents. The Tochigi Prefecture has over 2 million residents and some commute by high speed train to Tokyo. Carrying some of that dust on their feet every day.

    Researchers found after Chernobyl that cesium contamination lessens over time in agricultural areas because animals and people eat up and disperse the crops and wind and water move some down radiation away by streams.

    But they also discovered cesium-137 in forests has not diminished as much because of the land usage is not conducive to self-cleanup:

    "While people are getting progressively smaller amounts of radiation from agricultural products, the doses they receive from forest products are expected to remain high for decades to come, since the decrease in the level of radiocaesium will be very slow."

    SP: Tochigi has ski resorts, the imperial family has a villa there, and the land is over 55% forested. That means radiation will be there a long time and actually grow because Fukushima Daiichi is still emitting radiation into the air at a significant rate.

    The brain trust in Tokyo has decided the national forest in Tochigi is a wonderful place to store nuclear waste:

    Sayonara Japan…

      Interesting comparison, what happens to radiation levels in agricultural areas and in forest areas…

      Being naive, one might consider the more rapidly falling radiation levels in agricultural areas a success and the continuously high levels in forest areas a catastrophe. But it's the other way around. The more rapidly falling levels in agricultural areas mean that the unhealthy fission products are getting distributed across initially not contaminated areas or are bound in food products which will be transported, even exported, over wide distances to become food for many people.

      Radiation levels in forests, diminishing over time not much faster than the half-lives of the present radioactive isotopes would enforce anyway, are an indication that the contamination stays in place, is more or less locally bound by the local biosphere.

      That's why the only sensible thing to do after a GAU is to make all contaminated land (which does not come in the shape of a circle, by the way) a no-go zone for humans for centuries, to let it grow over by a wild forest and to make a tight fence around it to restrict the movement of animals as good as possible.

      And a thousand times more sensible is to decommission all nuclear power plants worldwide next week to prevent to have more GAUs in the future.

    It's to bad they don't till the soil esp. the farmlands. I don't remember if it was the EPA or NRC or some other agency guidelines that recommends special tillers to turn the soil upside down for about 3 feet to allow the ground to be farmable (I posted a link one time but can't find it now)

    Now it is to late as fallout begins seeping into the soil and plowing it now would be turning fallout back up. Has to be done soon after a major release.

    I can hear the arguments now about more continuous subtle releases with wind and rain borne fallout still and possibly are always scattering and settling out but it would have been a start. Might as well just bury contaminated soil in deep deep lined holes in the ground. Anything else is spreading it around. Water for crops and drinking will just have to be filtered in multiple stages, for what, decades or maybe centuries?

    • richard richard

      Hi razz, who will pay for all this extra processing, filtering etc?

      Has tepco.guv set aside a trust fund to compensate victims for eons to come?

      I'll bet you that don't. The gutless selfish mongrels care naught for others or the future.

      I recommend extracting the price out of tepco boards collective hide.

      Nukers will never admit the full cost of their abomination.

      They've ruined the world, let's make sure we ruin them.

      • razzz razzz

        I guess, richard, like Chernobyl just pretend it is not as bad as it is then lie about the true implications for decades to come. The entire world is footing the bill for the new sarcophagus being built Chernobyl. After that is built, where do you put the waste?

        Maybe move to Germany as they try to end NPPs although they are already bathed in fallout or maybe Australia where they have avoided having NPPs.

        Japan's population growth is something to watch, could be the telltale of things to come. Japanese have been raping the oceans for years, now fishing will be problematic. Like they never gave a rad count from that record tuna that was caught and sold at auction recently.

  • Time Is Short Time Is Short

    Is Japan getting ready to rationalize the growing awareness of their secret nuclear arms manufacturing/plutonium weaponizing?

      The term "nuclear terrorism" comes up in that article you linked, Time Is Short. I wonder what that might be.

      Does distributing across a country a lot of machines which will randomly explode and spew out tons of deadly fission products and thereby make vast stretches of that country lost for healthy inhabitation for generations, continuously holding on to that practice and announcing to build more of the same count as "nuclear terrorism" – or only if the perpetrators wear a turban?

      • HoTaters HoTaters

        Well, it doesn't matter what they SAY about what they're doing. The by-products of Japan's "peaceful" nuclear program speak for themselves.

        Maybe the "terrorism" clause will allow the Japanese to follow the U.S. example and classify anything which they don't want to have scrutinized.

        How convenient.

    Recent radiation plume maps after Sandy show high concentrations of radiation being emitted on the East Coast. Is Washington a little concerned about possible – read highly likely – East Coast NPP damage?

    Oh, it's just for baseline readings. Everything is OK. Just smile for the inauguration photos . . .

    • HoTaters HoTaters

      Time Is Short, I've been watching similar high readings near the San Jose Radiation Network monitor. Am wondering if Lawrence Livermore Lab is spewing, or some medical project has run amock. Fremont, CA, is very close to San Jose. The abandoned GE Vallecitos plant is close by, as is the city of Pleasanton.

      No one seems to have taken much note of the consistently high CPM counts near San Jose, CA. Not particularly thrilling to me, since I live roughly 50 or 60 miles to the northeast.

      This constant spewing of radioactive filth has no doubt gone on for a long time. The difference is: now ordinary people are watching and paying close attention.

      • HoTaters HoTaters

        Oh, and I met a woman who worked in an electronics plant near San Jose who got thyroid cancer from passing chip boards under her face during her final inspections. She worked in manufacturing, and said the boards were painted with some kind of radioactive substance, or contained a radioactive component.

        There must be thousands of people like this, living everywhere. Who will tell their stories? She is now disabled, and cannot work. Her company laid her off shortly after her thyroid cancer re-occurred.

        • HoTaters HoTaters

          My question is: if her employer knew she was working with a radioactive substance and her thyroid was constantly exposed, why wasn't she given protective gear?

    High radiation in several countries thanks to nuclear reactors. Biggest mistake man ever made.

    Couldn't have anything to do with release of radiation even today?

    Radioactive dust –
    is that what we're to be,
    in the fullness of Time,
    for Eternity?
    Or do we sweep out the dust
    of ideologies rusting
    and of the Elite
    no longer be trusting?
    Have we seen enough
    of their Life-web busting?
    Have we heard enough
    of their lies and their hustling?
    Are we tired of being treated
    like cattle they're rustling?
    Have we seen enough damage
    from their selfish lusting?
    Like a foul excrescence
    they lay on us still,
    a thin scum encrusting
    our placid Will,
    beneath which flow currents
    of Goodness and Rage –
    will we balance those forces
    and end Nuclears' Age?

    • DUDe DisasterInterpretationDissorder

      Thank you or-well , thats the BIG question indeed , will our globally combined efforts make a difference big enough fast enough , will we succeed ?
      But the answer for NOT trying we already know/have..
