    No problem, just dry it out, grind it up and pour it over the rice crop. Then burn the rice crop, sending the bad, unhappy radiation across the Pacific.

    • Fukushima radiation 500 times annual safety level in Evacuation Zone
      08/20/2011 By majiroxnews


      TOKYO (majirox news) — Radiation is at its highest point in the 20-kilometer Evacuation Zone around the Fukushima Daiichi nuclear power plant. It is equivalent to 500 years’ worth of the normal annual limit of artificial radiation absorption, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) said Aug. 19.
      Annual radiation absorption in the Koirino district of the Fukushima prefecture town of Okuma was estimated to reach 508.1 millisieverts (mSv) one year after the March 11 meltdowns, the equivalent of more than 500 years of the designated safe absorption level of 20 mSv.
      Thirty-five of the 50 points within the Evacuation Zone at which MEXT took radiation readouts also recorded levels that would exceed the 20 mSv level.
      Measurements were taken from 50 points located in eight of the nine municipalities that fall within the Evacuation Zone. MEXT calculated radiation levels in the area from March 12 to Aug. 11 and made its estimations of annual exposure based on the assumption people were spending 16 hours a day outdoors.
      The Koirino district lies 3 kilometers (1.8 miles) west-southwest of the Fukushima Daiichi nuclear power plant, which continues oozing radiation more than five months after going into meltdown.
      The figures MEXT released Friday were the first it has disclosed regarding estimated annual radiation absorption levels since the meltdowns following the March 11 earthquake and tsunami that hit the Tohoku Region.

      • Arizonan Arizonan

        Thank you very much for sharing this article. It contains the very important information, now shared with the Japanese people, that the radioactive contamination of half of the country will actually be getting worse over the next year, not better. This is an extremely important truth to share with the humans. It is more respectful to make sure they are aware of these truths, so that they can have a chance at planning a different life. This BS about letting people go back, about cleaning up: none of this will be possible until the out-of-control reactors are no longer emitting any radiation. That will be a very long time hence.

    • “They are MURDERING people. Folks, we aren’t talking about some omnipotent entity. We are talking about a god damn power company.” – bmurr

      I really like how you said that!!!

      I wish some MSM anchor somewhere would have the guts to say something similar on a ‘live’ broadcast. Now that would be ‘fair and balanced’… and the TRUTH!

      I also dream of a candidate who will have the guts to say something like that during a ‘live’ debate or interview. I’d vote for that person, no doubt!

      The topics going to come up soon… you’d think?

      I wonder if there are Vegas odds for who talks about the facts of what’s happening first.

      …And when I say talk about facts I don’t mean the standard NRC ‘talk back manual’ replies. (“no reason for concern”, “airplane ride”, etc…)

      I mean someone who will ‘speak up’ and say “HEY! We Need to PREPARE and TAKE MEASURES regarding THE proven Fukushima Fallout. We already should have. We then need to look at our own Nuclear Plants and systematically turn them off as quickly and safely as possible.”

      That, would make my day. That might give us all a chance at a better life.

      • BreadAndButter BreadAndButter

        Hi ChasAha, +1.
        I’m just afraid that to have a candidate proposing to quit nukes, there needs to be a certain percentage of the public who supports this point of view.
        Otherwise, that will be the last interview for that candidate, or not?

        Do you see that public opinion which would welcome green power in the US at the moment? That would be interesting to know, if there are any current surveys about that question.

    • BreadAndButter BreadAndButter

      bmurr, I totally agree. They are NOT almighty, they are just private companies who haven’t existed 60 years ago and probably will not exist anymore in another 40 years.

      And they will be facing some competition in the future! As soon as the first green energy companies (the independent ones, not the ones founded by the nukers) really expand and folks see that it works – then everyone will buy green energy and the nukers can shut down.

    • Arizonan Arizonan

      I like how you said it as well. I don’t think there are any governments left on the planet who are willing to put the interests of their own people ahead of the interests of corporations.

    • Irritated Kalifornian

      @ red red wine. Good Morning R.R.W. Regarding your post “NR’s are placed on fault lines because that is where the water the water is” Is that to say all nuke plants are built on fault lines because there is always water at the fault lines? Could you , or some one else, please clarify? Thank you in advance for any info. Have a good day. I.K.

      • Whoopie Whoopie

        Wow. You know what IK? That’s a very good question.
        Google brought me this:
        The New Madrid fault line essentially follows the Mississippi River from Illinois to Arkansas.
        So that tells me that water certainly does follow faultlines. At least THERE.

        • Whoopie Whoopie

          I think they might have meant:
          The River follows the faultline though.
          Hell if I know.

          • Whoopie Whoopie

            Well I should have read further:
            “Where quakes along the West Coast of the US cause a jolt in the underlying rock, the area surrounding the New Madrid is essentially mud, soil, wet from the mighty Mississippi and Missouri and Tennessee and Ohio rivers which join near the New Madrid fault line, and liquifaction thus affects a huge area”

          • Dr. Anne Lee Tomlinson Maziar anne

            I myself IMHO suspect that something happening at a nuclear power plant may cause the quake. Also, it seemed somewhat reasonable to me the explanation for the interconnection about excessive ionization above a nuclear power plant, the use of HAARP to change that, and the frozen methane below the surface of the earth. The worst thing is that the infrastructure of older nuclear power plants seems to be corroded too much to stay in service, and much too expensive and dangerous to build new ones without even considering the problem of spent fuel rods. Perhaps the spent fuel rods are partially responsible for all the excessive ionization in the air.

    • Arizonan Arizonan

      Welcome! Sometimes they just use up whatever river happens to be around. I don’t think there is a faultline under Palo Verde nuclear power plant outside of Phoenix, they just suck up all the river water they can and hold it in big evaporating pools. They could get water to boil out here by just putting a bunch a big black tubes coiled up out in the 110 degree heat. I have no idea how much of our Arizona water they use to keep those damn things cool.

      • I’m getting the data on that. Someone who has been researching this subject is sharing his findings and i can tell you that they are not good because radiation is released with the evaporation.

        It is going to take me some time to work through all the data he has sent.

        I will post eventually on my blog

        • Fall out man!

          Hi Majia,

          That is an interesting one. We have heard very little about how much radiation is released from the plants when they are actually working normally. I did pick up that they release enough Krypton 85 to change the conductivity of the atmosphere (making it more conductive)

          It will be interesting to see what you manage to glean from the data.

    • Sickputer

      One of the nuclear plants in America is built where there is no big body of water and uses affluent water: Palo Verde near Phoenix.

      I was interested to see how the Arizona power plant Red Hawk uses water so efficiently and it is a natural gas plant:


      New natural gas plants and new massive discoveries of natural gas in America could be the reason why nuclear plants AND new coal plants will be phased out for economic reasons.

      No need to have a green reason to stop the plants…just convince the financiers…they won’t invest in a dying whale….and the nuclear plants are beginning to stink like a dead whale washed up on the beach.

  • BreadAndButter BreadAndButter

    Well, why is the cesium amount rising in the SFP? Because they re-use the cooling water (or claim to do so), or not?

    • Steven Steven

      I don’t think they usually lose much water from the SFP’s (under normal conditions). If the SFP at R1 was losing water like R4 is/was(?) there would be little point in even taking this reading let alone mentioning it.

      I’m guessing it’s sitting there holding water as intended, but due to the ‘loud noise and white smoke’ noticed by TEPCO on the 11th March, something is amiss with the spent fuel assemblies. The lid is off that building, and it was raining lumps of MOX fuel on the 14th March… some of it could have plopped in unnoticed maybe. Otherwise the ‘hydrogen explosion’ in R1 might have caused some damage, rearranged things and set something going.

      No doubt Arnie will have a good analysis for us in a few days, I’m just guessing.

    • Arizonan Arizonan

      I am wondering that as well. What are some things that would cause the caesium in the SFP to double like that over time?? If it had been caused by flying fuel pellets coming out of the explosions, I would have thought the increase in radiation would have been noticeable then. In this case, however, June 24 readings are being compared to August 18 readings. It is during this time frame that the readings doubled. What would cause that??

    This little hummer causes all pollutants to fall out of the air in your home by neutralizing their positive charge.

    This is the best negative ion device that I HAVE used.

    Massive negative ion generation WITHOUT ozone production. Ozone combined with our 80% nitrogen atmosphere creates nitric acid, which damages lung tissue. PLEASE, never use an ozone generator!

    Negative ions can relieve depression,headaches, increase thought speed, open up your lungs, deter bacteria/virus/mold/pathogens from multiplying.
    All these effects I have observed over many years.

    When you take a deep breath in your home, your nose and lungs get that wonderful tickling feeling, as you feel when breathing the air right after a thunderstorm. Obviously I highly recommend this device.


    The balancing of the blade DETERMINES the level of performance.
    Balancing the blade CAN take up to an hour (call me slow).
    If the device gets dew/moisture on it, it will burn out.
    Keep device at least four feet from any electronic device that you value!!

    You will probably end up on some watchlist if you purchase any of the unique weapons offered by that web sites mad scientist. Fair notice

      I’ll let the Experts weigh in with you Majia.
      Excellent post though! I posted here:

      • Whoopie Whoopie

        Question about Majia’s comments:

        “There are 250 kilograms of Plutonium in each reactor (only 2.5 kilograms needed to make a bomb) and plutonium is escaping into the atmosphere­”

        I thought only one reactor has MOX fuel rods with Plutonium!


        • my understanding is that plutonium is a by-product of the uranium in the fuel rods and therefore is produced even when mox fuel is not being used.

          i wish I could recall the citation for this assertion but we discussed it here at enenews sometime ago

        • Further information on my understanding is that plutonium is a by-product of the uranium fuel fission process.

          check out this post by blogger Ex-SKF

          In this post, Ex-SKF examines Japan’s nuclear agency report on radionuclides released from the report. He links the pdf report.

          here is a summary of Ex-SKF’s reading of the report:

          “More plutonium came out from Reactor 2, 2-digit higher, not from Reactor 3 with MOX-fuel.

          Strontium-89 (in becquerels)
          Reactor 1: 8.2 x 10^13 (or 82 terabecquerels)
          Reactor 2: 6.8 x 10^14 (or 680 terabecquerels)
          Reactor 3: 1.2 x 10 ^15 (or 1,200 terabequerels)
          Total: 2.0 x 10^15 (or 2,000 terabequerels)

          Strontium-90 (in becquerels)
          Reractor 1: 6.1 x 10^12 (or 6.1 terabecquerels)
          Reactor 2: 4.8 x 10^13 (or 48 terabecquerels)
          Reactor 3: 8.5 x 10^13 (or 85 terabecquerels)
          Total: 1.4 x 10^14 (or 140 terabecquerels)

          Plutonium-241 (in becquerels)
          Reactor 1: 3.5 x 10^10 (or 35 billion becquerels)
          Reactor 2: 1.2 x 10^12 (or 1.2 terabequerel)
          Reactor 3: 1.6 x 10^10 (or 16 billion becquerels)
          Total: 1.2 x 10^12 (or 1.2 terabequerel)

          Neptunium-239, which decays to plutonium-239, was estimated at 7.6 x 10^13 becquerels, or 76 terabequerels, adding to 3.2 x 10^9 becquerels of plutonium-239 that came out. Again, most neptunium-239 came out of Reactor 2, whose reactor building is more or less intact and whose Suppression Chamber is said to have been damaged on March 15 morning.

          In the PDF file linked above, NISA estimated 770,000 to 850,000 terabecquerels of radioactive materials have been released into the atmosphere from Fukushima I Nuke Plant (although they are now trying to lower that number), and additional 720,000 terabecquerels of radioactive materials are in the contaminated water at the plant…”

          read the entire post at the link above

          Unless I am mistaken, I think we see in this report that plutonium is a byproduct of the fissioning of fuel that is not mox fuel

          • Sickputer

            It is well known plutonium is a byproduct of a regular uranium-loaded reactor.

            In the Unit 3 MOX reactor there was 982 pounds of plutonium brought over on a ship from France so it did indeed have a headstart over traditional fuel.

  • Irritated Kalifornian

    @ Whoopie. Thank you for acknowledging my post regarding the placement of nuke plants on fault lines. I hope you are out of the way of the hurricane. As you probably know Kalifornia is riddled with faults. It would be difficult to build a nuke plant out here away from a fault. However, having grown up in the Chicago area I have an interest in the midwest also & I took a quick look ,did not research yet, at the immediate Chicago area nuke plants & they appear to use Lake Michigan ( not a manmade lake) as their water source, as opposed to fault line water. Will be looking into this further.

    @ red red wine: Please try not to worry just yet about all nuke plants being on fault lines Will keep you posted. Sincerely I.K.

        “The cells of the stamen hairs of some Tradescantia (spiderwort)plants are colored blue, but when exposed to sources of ionizing radiation such as gamma rays, the cells mutate and change color to pink; they are one of the few tissues known to serve as an effective bioassay for ambient radiation levels.”

      The statue of bladder pathology in 164 resected during surgery on enlarged prostate, high doses of cesium (5 ~ 30 Ci/km2), intermediate dose
      (0.5 ~ 5 Ci/km2), divided into three groups to consider the non-residents of contaminated areas, as its mechanism, p38MAP kinase and NFκB
      Activation, indicating that the increased production through NO. Cesium-137 in these three groups of human urine, respectively, 6.47,
      0.29 Bq / L and 1.23, and the same level above the breast milk of Fukushima Prefecture, a precancerous condition of creating a long-term exposure
      Report is important.

      Transient peak in contamination of food. The detection system developed in a hurry to avoid the ingestion of food contaminated with cesium-137
      Has become an urgent issue that. Currently, workers are engaged in or nuclear accident, people continue to live in high pollution areas such as Village Restaurant
      The need to consider, such as pectin prophylaxis adsorbing cesium-137.
      We are obligated to offspring. Ban on nuclear testing through experiments published in the U.S. to detect low-level radioactive nuclear test

      Sure, long-term cesium remaining in the half-life of 30 years
      Has been the biggest problem is exposure of 137.
      ■ What is the cesium-137?
      Cesium-137, prior to the 1940s on the planet
      Most did not exist. Produced in fission of uranium
      Emitted in large quantities because nuclear and atomic bomb. Recently
      Has become a nuclear accident in the emission source. Since the

      Cesium-137 γ-ray emitting β-rays and a strong food
      Used to treat radiation exposure and cancer. Half-life
      Dangerous because it emits radiation over 30 years and long-term
      Be. In Goikonia Brazil in 1987, closed
      Cesium radiation therapy equipment in medical institutions that are
      137 is taken out, shiny metal contact as interested
      Contact and exposure were 250 people, that killed four rubber

      Cesium scattering due to this transient nuclear accident
      Is. Space radiation dose records in Figure 2 Mito
      Exhibits, there is a big peak on March 15, March
      There was a sustained release for a while from 21, this

      This trend is a common accidental contamination of this
      You can play with. Radioactive contamination of a significant portion of today,
      Attached to the particles emitted from nuclear power plants in clay soil
      According to the radiation from cesium-137 was attached to the minutes
      The thought, decontamination of the soil is the key.
      Cesium-137 contamination of the soil, yet these features like
      Yes, highly contaminated areas are called hot spots
      Decontamination is important. A look at nuclear power plants north of the regional
      Restaurant on the west from the village Nihonmatsu, Koriyama, Fukushima, etc. People
      Seen a lot of areas of high population density scattering (“Side

      Not satisfied with current law ■ – Improvement of the legal system is an urgent
      However, now when you start the decontamination of these
      Disaster Prevention Act of radioactive isotopes of the line (so-called
      Ru-proof method failure) is not compatible with the situation. The current “failure-proof method”
      Assumes that there is a small amount of highly radioactive material, “high
      Dose, “” containment, “” restricted area “Handling the basic
      That you are.
      However, the following Becquerel / kg handling 10,000
      Have not been regulated. So, “ask once diluted
      No problem “responses that are easily taken. In fact, small amounts
      Release of radioactive material is diluted, diluted sewage that is disposed of
      Essential that I have become. This small amount of whole
      Can not be assumed. But this time it Fukushima nuclear power plant
      The accident, which released huge low dose of radioactive material
      Has become a problem that others. For example, around the sewage
      In the processing plant, 500 tons of sludge and 8,000 Bq / kg
      The unexpected scale and accumulate. Tohoku University
      In the analysis of isotope Center, cesium in soils
      System is attached to the clay layer. This clay layer of sludge
      Used for making cement, the potential for enrichment
      Greater attention should be paid. Extensive removal of contaminated
      And if you use a lot of cleaning products, detergents containing
      And that a large amount of sewage flowing into the radioactive material
      File. The amount of detergent is used with caution.
      In this case, there impossible to contain spatially
      File. In some prefectures of radiation controlled area to the sewage treatment plant
      If you have been, the current law to handle controlled area
      There are strict criteria and specifying the radionuclide. For example,
      The University of Tokyo, but there is a controlled area network of more than 20 months, Fukushima
      Cesium has been flying in, facilities such as tellurium treated
      There are only four places. Under current law, also to the waste
      Has laid stringent standards, a large debris, sludge
      That is about to be treated in the extralegal. In fact,
      Because weak radiation damage to some extent if you put a distance
      Can be less likely. Rather scattered and are not inhaled
      It is important to be sold. Etc. So Minamisoma
      Are thinking short term, studies in the same local area
      School and district to fill the basement of the hospital away from
      Be. The uniform removal of lower doses even higher doses
      Le addition, high doses of those children as possible,
      The policy of removing the patient from touching sensitive area
      To promote faster Fukushima nuclear power plant decontamination, about the country
      Should make the system go all out for stakeholders.

      The amount is higher. About 20 ~ 30 km school zone
      The decision of the municipal government to stop letting uniform regulations
      As high priorities. And forced the evacuation of linking compensation
      Stop, all costs are paid by the government evacuation of residents and the Electric Power

    Where does cesium-137 come from?

    Nonradioactive cesium occurs naturally in various minerals. Radioactive cesium-137 is produced when uranium and plutonium absorb neutrons and undergo fission. Examples of the uses of this process are nuclear reactors and nuclear weapons. The splitting of uranium and plutonium in fission creates numerous fission products. Cesium-137 is one of the more well-known fission products.
