“Significant concentrations” of Niobium-95 were reported by Japan gov’t after 3/11 -Study

Title: Sedimentation and remobilization of radiocesium in the coastal area of Ibaraki, 70 km south of the Fukushima Dai-ichi Nuclear Power Plant
Authors: Shigeyoshi Otosaka and Takuya Kobayashi, Research Group for Environmental Science, Japan Atomic Energy Agency
Date: 13 November 2012


The accident of TEPCO’s Fukushima Dai-ichi Nuclear Power Plant (1FNPP) released a large amount of anthropogenic radionuclides into the environment, and is still affecting people who are living in the surrounding regions. MEXT (2011a) reported that significant concentrations of anthropogenic radionuclides, such as iodine-131, cesium-134 (134Cs), cesium-137 (137Cs), tellurium-129m, silver-110m, niobium-95, and antimony-125, were detected from seabed sediments off the eastern regions of the main island of Japan. Since most of the short-lived radionuclides decayed to a level below the detection limit, two isotopes of radiocesium, 134Cs and 137Cs, have been considered as the major radionuclides that should be monitored […]

Niobium: 95Nb is the decay product of 95Zr (64 days), so disappearance of 95Nb in used nuclear fuel is slower than would be expected from its own 35 day halflife alone. Tiny amounts of the other isotopes may be produced as direct fission products.

    The great fallacy is that once an isotope decays, the radiation is gone, producing a stable element or compound. When a molecule decays, the majority of the time, it decays into another isotope, some with higher energy states than the parent. The radiation doesn't go away, it just changes its signature and needs a new process to monitor it. Just because it disappears from the original scanner doesn't mean its stable.

      I remember researching exactly this. Funny how isotopes decay into something else that emits radiation. By funny I mean not at all. The decay rate tables for radionuclides is available on the internet for those that are interested.

      Since this fukumonster set off to annoy every living thing on the planet and I read, more on how the substances as they breakdown turn to something else. I get a lil scared about how do these elements react with my mulivitamines I take daily? I was reading that farmers were giving their animals boron to rid them of taking in extra rads and so far the government has not said no. Ok, that's the dilemma because I see lol, in elderly vitamins they have boron added, so should we do the same versus thyroid pills if non are available?

        Lest we forget the atomic bombs and dumping of radio active waste in the oceans and Chernobyl before Fukudaiichi..

        Weeping LuLu, i think your questions can be answered, at least partially, in the enenews forum: Methods for combating radiation and its effects. it's mostly an archive of info and lots of links. Hope this helps. I think your vitamin intake is fine, though some suggest different forms, but has nothing to do with radiation but preferred forms of one vitamin over another.

    I tend to think criticalities are occurring on a weekly basis thus it is as if we are starting from day one of the accident. I hope I'm wrong and please feel free to correct me but the more I read….

  • also, so many heavy long lived radioactive elements have been released, there may be a rut off Fuku, or in Tokyo Bay, where enough of them are building to form a critical mass… (from watching Mexicans and First Nation horse blanket gulches and black sands around San Bernardino for Gold…)

      AGreenRoad I like free things..but not this. Where's my return slip.

      They have to know Nuclear Power Plants are deadly, why do we still have them, why do they want to build more, nothing is worth this not even money.

        I think that Doctor Helen Caldecott is onto something important when she compares the male sexual thinking-distortions and male anatomy that seem to be in the subtext of all things nuclear. There is a certain psychology that seems to be going on…of course, with all this radiation though, men will all be sterile and will still be taking their viagra trying to prove to the world just how powerful they are/…arn't. (no offense intended to the good-guys).

    radiation is bittersweet… kind of like a death dealing snake that smiles while it is biting you.

    I don't know if this is written by pro-nuke professors but if they are not, might be worth a look.

    Dealing with radionuclides internally can be futile. Once deposited in the body after being UN-recognized as dangerous during uptake the decay rays become an irritant with the body responding by encapsulating the offending pseudo-mineral. Once encapsulated, it is almost impossible to be reabsorbed for elimination and has to be excised ex. thyroid nodules. If the rays have already done damage to DNA or to normal cells then cancer is the main worry even though it usually takes decades to show, depending on the amount of exposure or sensitivity a person has at a certain point in their life.

    In a healthy body, when you are older the body recycles or synthetically manufactures all the things its needs i.e. minerals, proteins, vitamins, etc. sans a few like vitamin E and B12, there is relatively little uptake of outside nutrients other than amino acids. This doesn't apply to kids as they are still adding mass. Neither does it apply to inhaling hot particles where they can embed in lung tissue.

    So, a lot of unneeded or excesses will pass through the digestive tract, radioactive or not. Not so in kids.

    Maybe some chelating agents will bind to heavy minerals to aid in excretion but could deplete needed minerals that have to be replaced.

  • In the present context when radionuclides are constantly being added to the biosphere at increasing rates, all life is being constantly reconverted to nuclear wastes. The result I believe is thqat one need not wait till a cancer develops decades later, nuclear waste input into the body will cause what used to occur in decades, much more frequently.Ominicide,extinction.

    i wouldn't be surprised if the japanese government discover significant concentrations of animositium and maybe even some of it's daughters like frustratium and delusionium.
