This NHK video below has no sound but does include onscreen captions in English.

Though not labeled in English in the video, it appears the river to the south is the Naka and north is the Kuji.

The hotspot appears nearby Fukushima Daiichi in NHK’s map, however it’s actually over 100km south. In reality, the hotspot is almost directly in front of Tokai nuclear power plant:

Tests done in the area in October 2011:

  • Ag-110m @ 416 becquerels per kilogram (Bq/kg) in dried abalone
  • Ag-110m @ 1,850 Bq/kg in dried abalone liver

    repost but relevant (thanks FD ;) )

    such as Mn54
    an isotope that is a large part of the shut down of a reactor..

    actually 83 percent

    found here (higher in sea sediment than in water)

    http://www.tepco.co.jp/en/nu/fukushima-np/f1/images/2012sampling/kakuhou_120720-e.pdf

    higher amounts were found in the previous month.. so where is it gone?? as well as the Ag110m..

    http://www.tepco.co.jp/en/nu/fukushima-np/f1/images/2012sampling/kakuhou_120704-e.pdf

    and thats not all

    the cesium levels were up to 1000 bq/l if i read these charts right.. wheres that coming from… and of course you cant beleieve the figures given.. they will be on the low side "statictically"

    page 11 on this shows the 1000 bq/l rise

    http://www.tepco.co.jp/nu/fukushima-np/f1/images/2012sampling/intake_canal_120721-j.pdf

    wonder where thats coming from??

    oh and theres this too Mn54 the facts..

    http://www.stanford.edu/dept/EHS/prod/researchlab/radlaser/RSDS_sheets/Mn-54.pdf

    so the Mn54 is the isotope to worry about here?? no mention..

    southerly movement of sea silt with land to sea transfer..

    NO diagram of sea to land transfer?? odd??

    no cesium in the abalone either??

      is this near a sea mount or sea canyon?? because that is where it will be teaming with life!! thats where you will find the food chain.. they also scavenge further afield but return to the safety and food security of the mounts/canyons..

        Does it matter if it is close to sea mound, the radiation will eventually contaminate these oasis of life, the building box of our ecosystem and ultimately end up in all living entities.
        Don't worry we may perish but nature will continue, it has a great abily to adapt, only without us.
        Probably for the best, this world is not just for mankind, I like biodiversity.

          @weeman: from day one, it was out of our hands. We were just a tad on the self-righteous side. Had we known there was no big 'safety net' in the sky, we might've been more realistic in our actions…

            Day one occurred a long time ago, during the manhattan project in Chicago I believe when they first archived sustained nuclear reaction.
            The scientists all knew the consequence and told the authority of the dangers, did they listen no, they were more intrested in its weapons capability and needed a way to fund, after war money was scarce, so free enterprise got involved and they put profit ahead of life.
            My dad told me not to play with things that I can't control or understand and it has served me well.

    and heres what the IAEA had to say about the disapearing silver of the charts above and nothing to say about Mn54 either.. in fact nothing to say about plutonium, strontium etc etc etc

    may 9th 2012 meanwhile deep in the bowels of nukepromote central..

    "Studying Marine Contamination

    Since the accident, the Japanese authorities and the IAEA monitored the marine radioactivity near the Plant site. Countries in the Asia and Pacific region requested the IAEA's support, worried that the considerable releases of radioactively contaminated water could reach their coasts, with possible damaging consequences for those communities and their economies. In June 2011, the IAEA Board of Governors approved an IAEA Regional Cooperation project to support countries in the Asia and Pacific region. Twenty-four countries are participating in the multi-year project Marine Benchmark Study on the Possible Impact of the Fukushima Radioactive Releases in the Asia-Pacific Region.

    The project will harmonize the analyses of various radioisotopes in marine waters, marine plant and animal life, sediments and suspended matter. The uniform measurement of the radioisotopes in the ocean will ensure that any impact assessment is comparable and verifiable across the enormous volume of the Pacific Ocean…"

    i dont believe that!! ;/

    you will unfortunately have to pass much IAEA blurb to get to the above paragraph.. sorry bout…

      "The project will harmonize" = IAEAspeak for "we will get custody of the data and then massage it until it looks the way we want it to before it is released to the public."

    The distribution kinetics of waterborne silver-110m in juvenile rainbow trout.

    Abstract

    Juvenile rainbow trout (Oncorhynchus mykiss) were subjected to a 2-day radioactive pulse of 110mAg at 11.9 microg/l (as AgNO3), followed by a 19-day post-tracer exposure to non-radioactive Ag(I) (3.8 microg/l). The distribution of 110mAg in the gills, liver, intestine, kidney, brain and remaining carcass was investigated over a 19-day post-tracer period. Initially, the intestine contained the highest proportion of the 110mAg burden (34%), however, by day 8, less than 5% of the total radioactivity remained in this tissue. The majority of the 110mAg eliminated from the intestine appeared to distribute to the liver. Eventually, the 110mAg content in the liver accounted for as much as 65% of the total radioactivity in the fish. Apart from the liver and intestine, only the gills and carcass contained any appreciable amount (>5%) of the total body 110mAg content. Liver and gill samples were fractionated using differential centrifugation techniques to discern the subcellular distribution of 110mAg in these tissues. In the liver, the 110mAg levels in the cytosolic fraction increased from 35% to 72% of the total cellular burden between days 8 and 19, respectively. The radioactive pulse in the gills was…

    “Soil is an element that forms part of the natural environment. In-organic and organic matter, micro-organisms and wildlife all utilise soil in some way or another during their natural cycle of circulation. More-over, soil is essential for human life. It is a foundation for agriculture and an important natural resource. Soil creates underground water reserves, possesses the capacity to retain water and maintain ecosystems.

       As for soil on agricultural land, although no new contamination cases have been reported tn recent years, 7,140ha of land has been iden-tified as contaminated, and measures are being implemented to address this problem. Concerning soil in urban areas, a total of 232 contamina-tion cases have been reported since 1975, and the number of cases where the nature of the contamination has been identified has been in-creasing recently.

       Regarding land. subsidence, restrictions on underground water pumping have improved the overall situation. However, in some regions, a significant amount of subsidence is still reported due to water pump-ing for agriculture and for melting snow”

    But this is not good for the Japanese nor wildlife ! we know that the sea silt will retain the isotopes and that will be a double whammy on the east coastal sanctuaries (some info and maps on other reports…the reports are slightly different on some topics every year, so its worth a browse!!

    shows maps of pollution in major rivers that could be correlated with future or present hotspots!

    talks about the build up in dams/resovoirs of contaminants because of design

    the report is part formulated by statistics from corporations given on a voluntary basis, or in the case of the nuclear industry, not at all!!

    no mention of the word nuclear at all!! except one time when they mentioned the german environment ministry with a long name with the word nuclear in it… but that is all.

    talks about sludge recycling and dumping of excess amounts, gives figures.

    also gives figures for industrial waste!

    refers to nuclear as “other” maybe on charts sometimes

    the economic stuff (sometimes under the term “trends”) in there was actually interesting… they lay out the question of ecology against profit and talk about mitigation of this problem by compensatory payouts to make up for damages!

    food for thought maybe?

      "Food for thought", indeed! And, an eye opener to ALL the various stuff being pumped into the environment, so much so that nuclear poison that normally leaks into the environment from operating a NPP is just an after thought compared with the tonnage of industrial and agricultural toxins. They would even have considered meltdown strength contamination. Good find, arclight.

    And five days ago naive Japanese parents let their children splash in the sea 35 km closer to Fukushima Daiichi than this hotspot mentioned today:

        It seems like almost a year that I listened to the song, Mad World, version Gary Jules I think. I listened to a bunch of variations, tributes, performances on the U tube. It became my most listened tune for a while. Then I noticed the tune on Smallville tv series. I have not listened to it much lately. The news on this website is pretty much Mad World stuff. The villains in Batman tv shows and movies somehow escaped into real life. Seems we only get the villains, not the heroes. Mad F'n world.
