Title: Observation of gamma-rays from fallout collected at Ibaraki, Japan, during the Fukushima nuclear accident
Source: Applied Radiation and Isotopes
Authors: Jun Saegusaa, Yasuaki Kikutab, Hitoshi Akinob
Date: July 2013

Abstract

Gamma-ray pulse height distributions were measured for a fallout sample collected at Ibaraki, Japan, during the Fukushima accident in March 2011. The fallout was collected in a pan of water and then evaporated to dryness on a stainless-steel holder. The sample was measured by a germanium detector three times over a year. In the pulse height distribution of the initial measurement, approximately 140 peaks were observed in the 50-2048keV energy region. Most of these peaks were either total absorption peaks or sum peaks of Te, I or Cs isotopes. Unlike fallout samples at the past nuclear accidents, nuclides such as Ce and Ru were not detected whereas 110mAg was prominently observed. The radioactivity concentration of 137Cs was determined to be at least 1.4×104Bqm-2, approximately 14% of which was attributed to rainout.

  • And, even "past nuclear accidents" (i.e. Chernobyl) may have been much more severe than advertised:

    WHY ARE THERE RADIOACTIVE WILD BOARS ROAMING NORTHERN ITALY?
    CORRIERE DELLA SERA, LA STAMPA (Italy)
    http://www.worldcrunch.com/food-travel/why-are-there-radioactive-wild-boars-roaming-northern-italy-/radioactive-boars-piemonte-hunting-chernobyl/c6s11160/#.UVOtwqLI6So

    "VERCELLI – This northern Italian city is more than 2,000 kilometers away from Chernobyl, so it’s almost impossible to imagine how the very same radioactive particles ended up here — or in the innards of 27 wild boars.

    Caesium-137 is a radioactive isotope, formed by nuclear fission on nuclear sites. The particle was infamously released into the environment during the Chernobyl disaster in 1986.

    The Milan daily Corriere della Sera reports that 27 samples of wild boar tongues and diaphragms from the 2012-2013 hunting season had been analyzed, which led to the discovery of the elevated levels of the caesium-137 — levels that are consistent with a nuclear accident. "

    Describing the contamination with such technical mumbo jumbo will distant citizens from the magnitude of the contamination we all must endure for eternity. Using the most conservative estimates of fuel released into the harbor to date, I would bet anybody a million dollars that one drop of that harbor water ,if taken internally, would kill a mouse within 12 seconds. This is the only sort of demonstration that really satisfies the enquiring mind.

    Valuable study! Some of the health problems – teeth and nails falling, make me think Fukushima resembles more Kazakhstan bomb test site, than other nuclear plant accidents.

      Or things like this, many of us have read from Japan as well:
      In particular, the Kazakh team recorded hemorrhaging of respiratory tracts, mouths, genitals, and changes in mucous and skin of those living in the area surrounding the test site. They also noticed a spike in those suffering from asthenia, or extreme fatigue. More often than not, victims would suffer from all of these symptoms at once. The study's findings filled 12 volumes of classified documents. Only after the Soviet collapse did this research become available to the general public.

      And what later researches show:
      Up to 1970, the esophagus cancer incidence was predominant, but it decreased thereafter, while the incidence of stomach and liver cancers increased. The second peak of excess cancer rates was mainly due to lung, breast, and thyroid carcinomas.

      The air releases are similar to bomb explosions, only with more core material spread throughout the atmosphere.

      The constant leakage into the ocean is similar to other nuclear spills, only on a far more horrific scale.

      Fukushima is the worst of both, by a large margin.

    I'm little confused by these (largely) non-news lately. 110mAg has been reported in Fukushima from the start – and regardign this study, 110mAg was the defining feature of Chernobyl accident so it's nothing new as such.

    It's interesting to note though that main source of 110mAg is said to be neutron-activation of normal silver. In Chernobyl I connected this to the silver-iodine seeding of clouds to protect Moscow, though most likely unjustifiably, as it's unlikely the fallout has had high neutron flux. Might Japan have likewise attempted to protect Tokyo with cloud-seeding? They seem to otherwise having taken every failed page from Soviet Union's Chernobyl response, so why not.

    Another consideration is the seal in the reactor well head is usually a silver composite, so the neutron activated silver could be further evidence the reactor containment(s) were seriously compromised. Chernobyl went prompt critical, so it could be interesting to explore whether the 110mAg might be a signature of prompt criticality.

      Gz sez: "Might Japan have likewise attempted to protect Tokyo with cloud-seeding? They seem to otherwise having taken every failed page from Soviet Union's Chernobyl response, so why not."

      SP: It's possible, but I doubt it. The Japanese government pretty much has given Tepco free rein to stall and lie since the beginning. It might be said there is no legitimate government now in any of the major countries of the world…just corporation big shots pulling puppet strings.

      To compare the bumbling Japanese nucleocrats (who can't seem to find their ass with both hands) to the well-oiled Soviet dictatorship is like comparing a piss ant to a tiger.

      About the only planes mobilized prior to the MOX winds covering Tokyo were the evacuation planes for families of Tepco and Diet big shots.

      Brazil was looking pretty good to them as well as Obama and his gutless entourage. Makes you wonder how many planes did fly multiple trips to Brazil between March 12 and March 18? Somebody in Brazil would have those stats.

    "…The world's nuclear fleet creates about 10,000 metric tons of high-level spent nuclear fuel each year.[96] High-level radioactive waste management concerns management and disposal of highly radioactive materials created during production of nuclear power.

    The technical issues in accomplishing this are daunting, due to the extremely long periods radioactive wastes remain deadly to living organisms. Of particular concern are two long-lived fission products, Technetium-99 (half-life 220,000 years) and Iodine-129 (half-life 15.7 million years),[97] which dominate spent nuclear fuel radioactivity after a few thousand years. The most troublesome transuranic elements in spent fuel are Neptunium-237 (half-life two million years) and Plutonium-239 (half-life 24,000 years).[98] Consequently, high-level radioactive waste requires sophisticated treatment and management to successfully isolate it from the biosphere…"

    2,00o miles sounds like a great distance and 100,000 years sounds like a long time, however in relation to the power of nuclear radiation it's not far or long. When mankind split the atom his perceptions of time and space needed to keep up with his new creation. Radiation is now part of our food chain and will be forever. Life on planet earth has changed.

      SP: Good…there are about 7 billion people who need to be shocked…every day until the nucleocrats and the frackocrats are driven into bankruptcy.

      It may take 5 billion dead from human pollution accomplish that, but on their tearful deaths we can keep humanity alive and Mother Earth recovering from her nearly fatal wounds.

      She is on her death bed for sustaining life on this planet. If she dies we all share the same fate.

          • We breathe mostly nitrogen, not oxygen, but …

            As 78% of the air consists of nitrogen, when we breathe the air most of what we breathe in is nitrogen.

            The nitrogen has no effect on the workings of our body and so it is emitted again when we breathe out.

            The only gas in the air which is used by our bodies is oxygen which, when we breathe in, is absorbed by the lungs and passed to the bloodstream.

            At the same time waste carbon dioxide is passed from our bloodstream to the air we breathe out via our lungs.

            Around 21% of the air is oxygen which is only marginally reduced in the air we breathe out which explains why we can give mouth-to-mouth resuscitation as there is plenty of oxygen left even in air we breathe out – enough to keep someone else alive during resuscitation if necessary.

            Yes, nitrogen is roughly 80% of the air you breath. However it simply acts as an inert gas, not being used by the body.
            Humans breathe air order to obtain oxygen (20% of air).

        That slide slow begins with thanking the workers at Fukushima Daichi in the wake of the disaster as heroes. (And many undoubtedly knew the risks, and were.) Then, "Their bravery saved Japan from massive evacuations." That's where I gulp a little. The Gundersens have to KNOW that Japan from the start STILL needed and needs to be massively evacuated. Arnie Gundersen went to Tokyo personally and said that soil samples marked the whole area as "nuclear waste." But maybe they realize they are dealing with a much wider population that is only now being brought into the loop. My husband and I watched the face of Naoto Kan, Prime Minister at the time the reactors blew. He gave the opening talk by videotape at the recent symposium in New York. A very sorrowful man. As he talked about the anguish of whether or not to evacuate Tokyo in the early days, you could see that however seriously that decision weighed upon him ("We nearly evacuated Tokyo"), he will never know if the decision was RIGHT. My husband and I looked at each other and said, he'll live with that the rest of his life, and it was very sad.
