Overview of active cesium contamination of freshwater fish in Fukushima and Eastern Japan, Scientific Reports 2013 (h/t Anonymous tip): [...] The serious accidents of the Fukushima Nuclear Power Plant have been contaminating a vast area in eastern Japan, home of 60 million people. Consumption of freshwater fish is an important part of the aquatic pathway for the transfer of radionuclides to the freshwater ecosystem creatures including humans. [...] we have to think that the contamination of freshwater fish is widespread not only in river basins but also all over the ground included all types of water-systems, for example, agricultural and urban water systems. [...] In this paper we show the relation between distance and contamination levels by inverse regression analysis. The results indicate the effects of quasi radioactive cesium 137 by the Fukushima accident look like less serious than those of the Chernobyl accident. However, contamination levels are possibly higher than the Chernobyl as the cesium is concentrated by the water systems in limitation region. Water paddy field look like shallow pond saved mud included cesium 137. Moreover, the cesium137 will distribute and concentrate by high density irrigation canal and urban water-system. For example, the highly contaminated Taisho river bottom soil Cs134: 4,335 Bq/kg, Cs137: 5,456 Bq/kg was found at 1/11/2011 at Kitakashiwa bridge of Kashiwa city in Tokyo metropolitan area, 200 km south-west from the plant. Therefore we must carefully and continuously monitor the contamination to the freshwater ecosystem and human health.

Professor Hiroaki Koide, Kyoto University Reactor Research Institute, Welcome to Fukushima (2013): The Japanese government reported to the IAEA about the situation at the Fukushima plant following the accident on March 11. They estimated the dispersion of radioactive material in the air. I feel that the report seriously underestimated the amount of cesium 137 in the atmosphere. According to my estimate, it is about 400-500 times greater than that of Hiroshima.

    Cesium, strontium-90 and plutonium/uranium isotopes are going to be embedded in Japan for a very long time. All over Japan. Not just central and eastern zones. Wherever the wind, water, rain, and snow blows from a little nuclear complex that is Pandora's Box unleashed.

    the people who closely monitor the situation will die about the same time as the people they monitor. The people who monitor the monitors may die sooner

    government appointed expert; "we bombed Japan everyday for 15 months with a Hiroshima bomb, but not a single death has been reported" "no immediate health risk"

    and didnt I read the actual figure may be 5000 bombs, and 15,000 bombs yet to "taint" the biosphere? Still, its not a problem because by the time the radionuclides reach the public, they will be highly deluded

          At this rate what is the actual count of infant mortality in India due to Fukushima? One must really take a baby death head count all India since March 11,2011. At the rate of 23 to 28.6 million excess infant mortalities in India from 1945 to 1997 compared to the prenuclear era 1911 to 1944 because of 477 PBq of Sr90 released, I estimate 84 million infant mortalities in India due to Fukushima because of the estimated 1200 PBq Sr90 released by Fuku by the three nuke explosions there. The risk recommendations of ICRP would have it as a big zero, the witches at IAEA and WHO applauding.

          That seems like wild extrapolation to me.

          If there was a million deaths in India, what is the number for Japan?

          I'm sorry, but there are many, mnay, many possible causes of infant mortality in India.

          Trying to blame all of the worlds' tribulations on Fukushima doesn't help the cause to bring nukes to a halt.

          We should fight the nukers with factoids. Although, we can use their obfuscation and delusion tricks as well. Never be afraid to use their own ploys against them.

          However, making up shyte just wont help. Anyone trying to use an empty, factless argument will be quckly overwhelmed by the nuker apologists (they have PR agencies and universities writing their diatribes).

          Rama is a good writer, we've seen him here before. But trying to prove a million deaths in India from Fukukuku is close to an impossibility. We need something tangible to promote.

            Disagree, since the jet stream dumps all over India and any radioactive isotopes still circulating will drop all over them. This is not a stretch of/for the imagination considering the size of the population and yes cancer is very rampant now in India. But then it appears its getting hit by the last 60 years of nuclear test fallout as well and the jet fuel filling our skies from all the jet travel too. 6000 fights a day over head in the USA and you can follow the jet streams around the world and you will find your cancers below were they travel.

            Based on the youtube video India is/has been the world's toxic dumping ground and that is bad luck for them!

            @ Richard … Japan has the worlds greatest population decline. More deaths, fewer births. A decline in population started in the 1970's but went negative around 2010. The greatest decline is in the Fukushima prefecture.

            Its difficult to attribute causes to effects. But one can take an overview, using some common sense, and the picture becomes clearer. Contamination of all kinds leads to reduced health, increase in death and reduced fertility. In fact the biggest reason for illness, one often overlooked, is that people have become unhealthy. The salient point is that a worldwide system of resource and human exploitation…really a mindset is at the essence of it…has lead to the pollution, deforestation and desertification that is at the heart of the global mass extinction underway. first the wildlife will suffer the greatest loss, then humans will follow. Pointing the finger at nuclear with robust statistics will not solve the greater problem. No rigorous analysis is even required, if one has a level of common sense and connection to nature.

            Humans were a scourge upon the earth. In my view, its ok that they perish and the earth starts anew in some millions of years

              Japan population is dropping around 280,000 per year. India is still increasing. Japan is seeing the most rapid decline in population of any country on earth, according to the World Population Data Sheet produced by the U.S. Population Reference Bureau. Its of course ridiculous to argue that radiation is not part of the decline. With some wildlife showing genetic symptoms in over 35% of population, like deformity and small brains, it is easy to project that humans will follow a similar path. The tipping point is the biggest unknown factor. At some point, famine, social breakdown and even environmental collapse on a large scale will occur. This will be a "flood" of misery

    It is interesting that uranium is a finite source here on earth and there could be shortages or might simply run out of it.

    Plutonium is more interesting as reprocessing plants are used to reclaim it as fuel for reactors or bombs, when it is reclaimed once then used as fuel again, it can't be reclaimed anymore for fuel because it is no longer arranged correctly on the atomic level to burn correctly (inefficient).

    Thorium reactors need a reprocessing plant built along side them to keep exacting the nuclear wastes to prepare them for re-burning back in the Thorium reactors. The extraction byproducts, chemicals and wastes needed to be dealt with in long term storage and associated costs are enough to make the entire operation a fallacy.

    Keep in mind that the bombs of Hiroshima and Nagasaki together totaled less than 5 pounds of fissionables, less than 15% fissioned. Each fuel rod contains about 450 pounds of fissionables.

International law prevents dumping of nuclear waste at sea, but that complex of plants is on the French side of the English Channel and the dumping is "legal."

      The damaged and un-contained melted reactors are migrating further and further away from the site by erosion. First they were melted inside the reactor core itself, melted through to primary containment. Once out of containments the melts are free to decay away in open air, ground and water. Next they show up in observation wells, then outfalls into the harbor and then up and down the coast and in waterborne plumes.

      If only the blasts of the units were the only radioactive releases, maybe the situation could have been dealt with but parts of the core melts are stored in some kind of liquid form in the leaking tanks farms onsite. Even that temporary containment fails and ends up in the environment.

      The fuel pools are a separate issue but have the potential to be more dangerous than the melted cores.

        Fukushima Daiichi Site: Cesium-137 is 85 times greater than at Chernobyl Accident
        April 3, 2012
        “…I asked top spent-fuel pools expert Mr. Robert Alvarez, former Senior Policy Adviser to the Secretary and Deputy Assistant Secretary for National Security and the Environment at the U.S. Department of Energy, for an explanation of the potential impact of the 11,421 assemblies.
        I received an astounding response from Mr. Alvarez [updated 4/5/12]:
        “…’ Based on U.S. Energy Department data, assuming a total of 11,138 spent fuel assemblies are being stored at the Dai-Ichi site, nearly all, which is in pools. They contain roughly 336 million curies (~1.2 E+19 Bq) of long-lived radioactivity. About 134 million curies is Cesium-137 — roughly 85 times the amount of Cs-137 released at the Chernobyl accident as estimated by the U.S. National Council on Radiation Protection (NCRP). The total spent reactor fuel inventory at the Fukushima-Daichi site contains nearly half of the total amount of Cs-137 estimated by the NCRP to have been released by all atmospheric nuclear weapons testing, Chernobyl, and world-wide reprocessing plants (~270 million curies or ~9.9 E+18 Becquerel).’…”

              At the same time, it gives us the crudest way to predict what may be in the future. If 60 million died from bomb tests, and if we have a similar release, then, barring for a wee second the bioaccumulation, the tipping points etc, we could expect 60 million more deaths. Of course, you would be eager to point out that the damage is accumulating, and this is true. A tipping point will be reached which will probably kill most life on the planet. In the meantime the suffering is incalculable. Why dont you have a crack at it: what thinking could motivate our most prestigious institutions, scientists, politicians and media to lie about Fukushima and support more nuclear?

                  yes, Anne, whether its 7x, 85x or 12000x worse than Chernobyl or the Bomb testing era, it makes little difference ultimately, what with all the reactors sitting on the bottom of the ocean, and all the spent fuel pools yet to blow.

                  Whats the point then of trying to expand awareness if its waaay too late to save the planet? If Fukushima was, say twice to 7x as bad as Chernobyl, as it stands, then there is a point to shutting down NPPs, and trying to remediate, in some way. but if its already 12000x worse, then it seems like there is no hope whatsoever for even the next generation, regardless what you do.

                  I dont think nuclear and its consequences are beyond the comprehension of the top scientists and the well informed politicians who must have a dossier on the desk straight form the DOE. But all your points are well received

                  Well, of course, it does matter. And the figures assume that the radiation spreads evenly around the world, and we know that the spread of radiation is very uneven, some locations getting much less, and some much more.

                  So it is important to shut down all reactors. I believe that it is possible to shut down all reactors. Some countries have already decided that they will never have nuclear energy or weapons. The medical profession through education kept the US free of any new nuclear reactors for 30 years.

                  As soon as countries realize that nuclear will totally bankrupt their economy, then nuclear will no longer be desirable. As soon as countries realize that nuclear energy and nuclear weapons production and used of depleted uranium weapons are the greatest reason for climate warming and ice melting, then they will turn against all nuclear. As soon as countries see that Japan has been almost totally destroyed because of nuclear and that the human deaths due to radiation are absolutely huge and the destruction of the human genome will render the human species extinct, they will all ban nuclear.

                  Will this come soon enough? I hope that it will.

                  Education matters. Hope matters. Stopping nuclear energy and weapons is the greatest challenge humans have ever faced. Once this is realized, humans will rise to meet the challenge.

                    If the moon spiraled out of its orbit into earth, would maintaining hope be of any value, or would it be better to accept the inevitable? So whats closest to the truth of current release; 1/2 or equal to bomb test era, 2x, 7x, 85x, 500x, or 12000x Chernobyl. All these figures are floating around

    We need very accurate, low-cost, widely distributed detection tools, monitors that can measure A, B, and G radiation. We need these globally. Think of the "One Laptop Per Child" program that aimed at a $99 wind-up powered computer. With mass production I think the top-flight devices that today go for $600 to $1,000 dollars could be sold for a fraction of that through an NPO/NGO. It would be a great Kickstarter project for the right persons, and the owner-operators could make a fair living from the proceeds methinks. With the right devices, nuclear power advocates will be overwhelmed by FACTS, widely collected, distributed, and validated.
