Gundersen: This video “confirms our worst fears” — Scientist: Reactor core materials found almost 500 km from Fukushima plant — 40,000,000,000,000,000,000 Bq/kg — Can travel very, very significant distances — Hot particles found in 25% of samples from Tokyo and Fukushima (VIDEO)

Fairewinds Energy Education, Apr. 3, 2014:

  • At 0:45 in — Arnie Gundersen, Chief Engineer at Fairewinds Energy Education: If Fairewinds Energy Education was a Japanese website, the State Secrets Law would likely prevent us from issuing this video.
  • At 1:15 in — Marco Kaltofen, Civil Engineer & Ph.D. Candidate at Worcester Polytechnic Institute (WPI):  In looking at indoor environments, they tend to be much more contaminated than the surroundings outside. Houses act like a trap and they tend to collect outdoor contaminants and they expose people as much as 24 hours a day.
  • At 9:15 in — Kaltofen: The sample that we got came from Nagoya in Japan, its 460 kilometers from the accident site. That’s about 300 miles away.
  • At 9:30 in — Kaltofen: It’s actually in the size range of dusts that can be inhaled and then retained in the lungs. This is important because if your health physicist and calculating and you’re calculating the dose that you would get from this particle you’d have to consider that this particle might actually be trapped and result in a lifetime exposure.
  • At 10:00 in — Kaltofen: The particle we examined was a mixture of fission products from a nuclear reactor and nuclear fuels. We looked at materials like tellurium, radium-226, we saw cesium-134, and -137, cobalt-60, and a whole zoo of isotopes that probably you’ll never hear about on CNN […] 80% by weight of this particle was made up of pure reactor core materials. That tells me that something that came directly from the accident, directly from the core can escape containment and travel a very, very significant distance. So it’s a long distance to travel and what happens is the particle is so very small that it will essentially travel with whatever gas it’s entrained in. The winds will blow it long distances.
  • At 12:00 in — Kaltofen: This material was in the peta-becquerel per kilogram range […] 4 followed by 19 zeroes — that many Bq/kg. That’s a very, very high number. […] It is a tiny particle […] about 310 becquerels for the particle.
  • At 14:00 in — Kaltofen: If you look at the black dust – and we’ve received samples of that from Namie and Iitate, and a couple of other communities in northern Japan, this is very similar to the black sand that people see. The black sand – and this particle, too – it’s an aggregate, it’s a mixture. If you think of a hunk of concrete, it’s actually a mix of sand and cement and small stones, that’s what it looks like under the microscope.
  • At 15:45 in — Kaltofen: For our Japanese samples from Fukushima Prefecture and from Tokyo, about 25% of those samples contained at least a few measurable hot particles.
  • At 16:15 in — Kaltofen: This data [was put] before a peer review panel at WPI.
  • At 16:45 in — Gundersen: It is solid scientific material like this that you will not see or hear via traditional news stories, Tokyo Electric, or the IAEA. Fairewinds has long said that there will be significant increases in cancer in Japan as a result of the Fukushima Daiichi accident — and this video describing just one hot particle, confirms our worst fears.

    Pass the butter, Japan is toast.

    • wildandfree wildandfree

      Realistically, we're all toast, but we knew that a long time ago here at ENEnews, this discovery / report out in the open now is just confirmation. I need to get a different calculator as mine won't handle 20 characters, in truth, I guess I really don't need it as wrapping my head around so many zeros is intolerable. Kind of like the Tepco lies. Now to just get others to recognize the situation and stop the bickering about who's study is best, we all know that walk ten feet and get entirely different readings and for some researchers, the lower numbers, if not lies are found under rocks or some other protective area they chose to test.


        just figured-out your avatar, wildandfree. Sorry for going OT, but it's really good…

      • m a x l i

        @wildandfree, you read that "found under rocks" thing somewhere, or are you speaking in more general terms?

          WNTF, if you are haivng colonic issues please write to me off-list. Have had similar issues & can share easy-to-implement things from my integrative medicine doc. Had serious vagus nerve issues post-Fuku, it basically paralyzed portions of my gut. Had terrible elimination problems & frozen sphincters. Bad news.

          I do a really simple breathing exercise now. The 4-7-8 count is important & it helps settle the nervous system & gets the body out of fight or flight mode. Helps get the parasympathetic nervous system working. Here's a link to a video demonstration & Wikipedia article on the parasympathetic nervous system. Do maybe 3-4 times at first.

          IMO the damage to our bodies is harming our glandular systems, adrenals, & it's putting us into a highly stressed "fight or flight" mode. My doc says 80% of our time should be spent in the parasympathetic nervous system dominant mode (resting state), & only 20% in the sympathetic nervous system mode. My doc also says modern people operate with the nervous system working opposite of the way it should (sympathetic dominant).

          Doing the exercises has REALLY helped me.

          Hope your relocation search is going well. Sorry you are having to do it after settling in NM; it is beautiful.

        unfortunately you cant change whats happening to our Ocean ecology food chain planckton oxygen and beautiful wonderful planet that we had for so long now dying before our eyes.WE are losing Mother earth and we have no other home.In the process of grief many of us are going through all the stages.The first was when we all started realizing that this process of losing Earth and its oceans and atmosphere and species ..And there was no way to ever accept this.Let those who want to put their brains into robots so they can live forever let them last in this prison planet forever. AS the earth becomes a prison where only going to the deepest ground do they have a chance to survive until they crash into another solar system many thousands of yrs away…Thats what a rogue planet which this will be will eventually do..

        eatliesndie….from time to time when yellow (sand?) dust rises up in storms in China, it eventually makes it way across the Pacific and gets dumped on British Columbia and beyond. Not to forget that more dioxin gets to Nunavut in northern Canada than elsewhere in the USA. That was discovered after a check on mother's milk among the Inuit there.

        But what with the big change in the jetstream of late, the flow patterns now have to be different. I guess this has to be a matter of grassroots individuals available taking measurements and coordinating results for us to know the whole of it.

        • eatliesndie eatliesndie

          dioxin – the other fallout…the fuel flea's kid brother…

        • Radio Radio

          Great points, PaciFistic. Going along with your comments, Japan has held back lots of food stuffs from the market and is suppose to be testing anything for sale locally or internationally, while none of the other countries, China, the US, South America, or anywhere, are testing at all. So, it makes sense that more comes from China at this point than from Japan. Also, and maybe this is one of your points, foods are seasonal – on one day the rads will be high from one location while low in another. The testing probably needs to be done over years, not months.

          • Fall out man!

            Japanese "testing" was originally designed to find nothing. For example, they were running geiger counters over the back of beef animals to test if they were safe to eat. A pointless show designed to find nothing and pretend its business as usual. When they started testing rice, it turned out the testing was voluntary, where if a Farmer was concerned, he could have a rice sample tested. How many people would want to test their rice when a positive test might put them out of business? Some time ago France rejected Japanese tea shipments as being too radioactive. The Japanese response was to test the tea, and dilute highly contaminated tea by mixing it with safe tea until it came in under official limits. Of course that still doesn't take into account the problem of hot particles that the article above is talking about. That contamination is very difficult to test for, and really eating food that may potentially have a hot particle is just playing Russian roulette (or Japanese roulette in this case). In testing the level of radiation on locations, the Japanese would clean an area around a radiation measurement unit to do everything they could to keep tested background readings low. One Enenews report mentioned the Japanese govt asking a US manufacturer of Geiger counters to change those bound for Japan to read lower! In another article on this site, a US testing firm sent to Japan was surprised to discover all their counterparts in Japan had deliberately low readings.

            • Fall out man!

              ie, test results are highly politicised, and the Japanese government testing is not trustworthy. I think the much higher readings for various bores and test points around Fukushima now are likely just the Japanese actually reporting some more realistic results. In the early days they'd do a test, report an insanely high rad level, then later say they were mistaken. Other reports would indicate the impossibly high level was right. When the Russians did any testing around Chernobyl, all personnel were told to divide any reading they took by 5 before reporting it. But in the early days of Fukushima, some Japanese testing was divided by up to 10,000! They just made it up as they went.

    Is that 40 quintillion? Um, holy shit.

    I hate to beat this story to death, but here goes…..

    On 3/10/11 I asked my sons if they had seen The China Syndrome. They had not. I explained to them the eerie prediction in the script about "contaminating an area the size of Pennsylvania" (before TMI), and then discussed TMI. I was on the West Coast at the time and was scared for my family back East. We spent the nite watching You-tubes of trailers and TMI stuff.

    Then 3/11/11. When we saw Unit #1 blow my second son said "wait a minute dad is this real time, we were just discussing this nuclear stuff?" When Unit #3 was on line….hoo boy was I ever glad my sons knew of my concerns and experience with the horrors of our nuclear era.

    Hug someone now. Live for today. Your tomorrows are dwindling.

    Hang in there all.

    • We Not They Finally

      You're SO not alone, Nick, and you should tell the story. Our own story is that husband was at the kitchen table earlier that week and kept repeating, "Something terrible is about to happen. It's the beginning of the end." He had never done that before. So when it happened late that Friday night (really into Saturday,) we knew. And we can't ever UN-know.

      And it seems like a huge burden to know – for you,for us, for anyone. All this time and ongoing. But really it's a sad entrustment. How terrible what is/will-be happening to people who do not even have that knowledge.

      So stay well and strong. And it is FINE to re-tell your story.

        Why "a joke"? It's a critical study that had to be done. And as Gundersen said, God knows what would happen to anyone now within JAPAN trying to get traction with this.

        And I know that you just meant it was over your personal limit and maybe seems like too much to bear. And for Ontological, you've already been made sick and that's tragic.

        But let's still all try to bear it for the sake of people who don't know and need to and still might listen. All we might have left by the end is our HUMANITY. "No joke."

    Fukushima radiation ‘unlikely’ to increase cancer rates – UN report

    Dispelling fears of an increase in cancer cases similar to the aftermath of the Chernobyl disaster in 1986, UN investigators claim cancers levels will “remain stable” in Japan.

    "No discernible changes in future cancer rates and hereditary diseases are expected due to exposure to radiation as a result of the Fukushima nuclear accident," UNSCEAR (United Nations Scientific Committee on the Effects of Atomic Radiation) said in a statement accompanying its nearly 300-page study.

    The report, entitled ‘Levels and effects of radiation exposure due to the nuclear accident after the 2011 great east-Japan earthquake and tsunami’, attributes the limited impact of the nuclear disaster on the Japanese public to “prompt protective actions on the part of the Japanese authorities following the accident.” Additionally, the study’s authors ruled out a rise in hereditary diseases and babies born with birth defects.

    For those people new to this, cesium 134/137 are fissionable atomics directly linked to an atomic bomb chain reaction. It is not normal, it is an abomination of nature. To associate it with natural radiation that is not of an atomic reactor bomb chain reaction is a crime against humanity. Cesium 134/137 is man made; not nature made. Liars compare fruit, water and vegetables with the grim reaper. Beware those whom worship the false god dollar the great, for their time is at hand.

    Dogs of mars want these atomic bomb reactors to power their paedophile HAARP transmitters to rape the children of earth from their future freedom.

    For centuries generations have warned us of these times. There are times when intervention is required to restore democracy and visible truth. These days have arrived. Stand before your children and tell them you condemned them to a gas mask future or wake the Fukushima up. Cowards lick the boots of devils devoid of humanity; Anti-humans.

    "Cesium 134/137 is man made; not nature made." – The great hubris is to think that we are somehow separate from nature. Take for example, the notion of object proliferation. If you study some of the most Indigenous peoples you will find that those with the fewest objects almost always have an incredible respect for nature. They would make bowls from leaves, letting nature return it to the earth. They live in and respect nature, because they understand that we are part of nature.

    Modern culture disrespects nature, toys with it, views it as separate, a commodity to be exploited, while in the end, all modern culture has to offer you is a blind leader and a dead end.

        Isn't Westinghouse the Koch brothers?

So bow down before your new neofeudal overlords the Koch brothers. Our descent into fascism is complete. Reminds me of a quote by the great Manly P Hall, "even if you ruled the entire world, you rule but a grain of sand." Dickheads! I'm sorry, I really have no patience when it comes to the enclosure, rape and destruction of the commons and people who get their wealth off the backs of the poor.

    Freedoms just another word for nothing left to lose 🙂 Im ready. Lets tell em all and see what happens.

    It's interesting how Mr. Kaltofen walks us through exactly how to isolate a hot particle and potentially ID it as coming from Fukushima. I imagine such techniques, when applied to, say, a lung tumor, could reasonably establish causation, and thus culpability. This is particularly true of the highly radioactive type of particle Mr. Kaltofen identifies in this video.

    Given the sheer scope of the liability, I hope his work does not venture into the macabre effects of this entire mess. Sometimes it's really better to toe the line and speak only of the "average" exposure from background-like sources. If people found out that a reactor didn't just melt, but literally went "boom," the outrage would grow and wealth would shrink. Unacceptable. At whatever cost. Tread lightly.

    Some conceptual calibration seems pertinent for this story.

    Note that the astonishingly high value of 40,000 PetaBq is essentially a density type of measurement.
    It is a projected number in order to be able to use kg as the mass reference.

    It is what would be measured if there was a full kg of the material.

    The actual particle produced 310 Bq.

    Now here is the kicker, of a sort.

    That 310 Bq particle is the same as 18600 cpm if one could get a count on it with something like an Inspector.

    I think that the 18600 cpm is a reference that most of us here can relate to instead of some off the charts extrapolation.

    Still scary even for just one small particle!!

    JoyB…help me out here if you care to pontificate more on this.

      @ fireguyjeff – Interesting details.

      But re. "That 310 Bq particle is the same as 18600 cpm if one could get a count on it with something like an Inspector." –> An activity level does not correspond to a 'count' as such. Distance between the Geiger Counter and the emitting source is key. Ever taken a smoke alarm apart to see how a Geiger Counter responds to the 37 kBq of Am-241 inside? Distance matters.

      Play around with the dose calculator linked to on my Radiation Units & Conversions page and you'll see what I mean:

      • fireguyjeff fireguyjeff

        MVB: I realize now that I should have capitalized IF.

        Quite right, distance does matter.

        It was clear in my mind that Prof Kaltofen's measurement(s) are not readily duplicatable with cheap gear.

        Just a consequence of consciously trying to not over detail in my posts.

        I was just hoping to clarify the nature of the large number vs the actual number.

        I have been too chicken to dismantle any smoke detectors knowing not to be casual in any way about the Americium.

        • MVB Michael Van Broekhoven

          @ fireguyjeff – Right, but you'd need to surround it (like 6+ pancake tubes creating a box-like enclosure or something) to get close to that (added-up) total CPM.

          On my Radiation Units and Conversions page, , I touch on the different units. On it are also a Decay Caluclator ( and Activity-to-Dose Calculator (, and more info that I have found helpful to make sense of this very complex stuff.

          If you have a rough idea what CPM level corresponds with a µSv/hr dose rate for the Geiger Counter you have, the RadPro Calculator can help getting more clues for how such a "hot particle" could affect a Geiger Counter.

          For example (w/ distance: 0.1cm , no added shielding; Bq for activity & µSv/hr for dose rate): If the 310 Bq was ALL ONE isotope, the dose (at 0.1 cm) would be different depending on the isotope:
          Pu-239 -> 0.00139 µSv/hr (half-life: 24,11 yrs)
          Am-241-> 1.23135 µSv/hr (HL: 432.2 yrs)
          Cs-137-> 23.6869 µSv/hr (HL: 30.167 yrs)
          Cs-134-> 61.4983 µSv/hr (HL: 2.0648 yrs)
          I-131–> 15.0107 µSv/hr (HL: 8.02 days)
          Co-60-> 95.3011 µSv/hr (HL: 5.27 yrs)
          K-40 –> 5.7322 µSv/hr (HL: 1.28 billion yrs)

          So, while 310 Bq of super-carcinogenic Pu-239 would barely affect a Geiger Counter, 310 Bq of natural K-40 would; & Co-60 and others would sent it soaring.

          (Geiger Counters are almost useless to assess the…

      Thanks FGJ, MvB
      that calculation helps to visualize this just a tad…

      But for example, if the number is 18600 cpm on sensitive monitors, does anybody have a guess how much cpm this black dust in Nagoya might show on an Inspector ?

      Because if 18600 cpm black dust is flying around there everywhere, wouldn't everyone be dead by now? Or am I confusing apples and oranges again… ??

    The problem with coming down with any disease from these particles is that even if one is fortunate enough to beat it there are still all of the particles in the next breath, drink of water, bite of food. We are experiencing life overwhelmed.

    please forgive/ off topic: Felt the need to add a moment of an open window to the thread, even if only energetic:

    May the long time sun shine upon you
    all love surround you
    and the clear bright light within you
    guide your way home

    HAve you seen where Alps has gone anyone? bloody waste of time and money..

    In line with Japans secrecy laws and the Trans Pacific treaty and trans atlantic treaties coopyright laws (know you can see whu they NEED copyright laws and how they are getting around the opposition)

    qiuck mispelling so you know its me 🙂

    sorry about the multi link admin but they are a natural (not that i ususally gamble)

    peace to all the enenewsers and keep the faith.. we are winning imo

    just have to bust decommissioning by melting in nitric acid (causes NO2 pollution)

    downwind from la hague and sellafield and we get this data to get the ball rolling….
    wonder where all the nitrogen is coming from?

    As I think Wynd said here the other day, "WHOA."

    Just cleaned my HEPA filter pre-filters today. They've been in place since about June, 2013. Already black inside (main filter) and needing to be replaced.

    Also pulled down the air intake filter for the HVAC system today. Coated with lots of goop, very thick brown dust.

    Will have to change the filters for indoors more often. Have to remember that the HEPA filters were in place when we were getting really high airborne CPM counts per NETC here last fall. And the fuel/spent fuel was being pulled from Unit #4 SFP.

    Am sure there's a lot of hot garbage in those filters. They will be handled with gloves, full body cover clothing, and will likely wear a high rated NIOSH mask when they get replaced.

    Will have to be a lot more vigilant about replacing the HVAC intake filter. That one looked really nasty, and it didn't take long to get that way.

    Kaltofen has a good point when he talks about indoor air environments. Keep those HEPA filters running, people! Also — Arnie Gunderson mentioned doing wet or damp cleaning when dusting. Am thinking that's a really good idea, along with periodically steam cleaning the carpets and adding some baking soda, borax to the cleaning solution, before a final rinse and removing the excess water. Will be trying to do that every six months or so if time allows.

    If I had my druthers, there would be NO carpets in my house; just throw rugs.

    According to new statistics for all 47 prefectures, released by the National Cancer Center Wednesday, an estimated 865,000 people were diagnosed with cancer in 2012, up 14,000 from the year before. Men accounted for some 504,000 of the total, while women made up 361,000.

    Notice again the data Stops at 2012.
    In this world of technology your telling me you can't provide information from the last 4 years?

    It was too early to provide a prognosis for the boy with the brain cancer, let alone to offer real comfort to his distraught family. Yet, in a town where doctors used to rarely come across a child with cancer, never mind brain cancer, they now see these traumatic cases crop up almost every month. Too many young patients are ending up dead, some barely out the womb but with bodies riddled with disease. Then there are all the women getting breast cancer unusually early, the men with lung cancer despite never smoking, the children born with Down’s syndrome despite the comparatively young age of their mothers.
