Dr. Kodama: Tokyo radiation “continuously high” since raining on March 21

Fukushima radiation alarms doctors, Dahr Jamail, August 18, 2011:

[Emphasis Added]

[Dr. Tatsuhiko Kodama, a professor at the Research Centre for Advanced Science and Technology and Director of the University of Tokyo’s Radioisotope Centre] believes things are far worse than even the recent detection of extremely high radiation levels at the plant. […]

Kodama, who is also a doctor of internal medicine, has been working on decontamination of radioactive materials at radiation facilities in hospitals of the University of Tokyo for the past several decades. […]

Kodama is an expert in internal exposure to radiation, and is concerned that the government has not implemented a strong response geared towards measuring radioactivity in food. […]

According to Kodama, the major problem caused by internal radiation exposure is the generation of cancer cells as the radiation causes unnatural cellular mutation. […]

Kodama believes the government needs to begin a large-scale response in order to begin decontaminating affected areas. He cited Japan’s itai itai disease, when cadmium poisoning from mining resulted in the government eventually having to spend 800 billion yen to decontaminate an area of 1,500 hectares.

“How much cost will be needed if the area is 1,000 times larger?”

More from Dr. Kodama:

  • We had rain in Tokyo on March 21 and radiation increased to .2 microsieverts/hour and, since then, the level has been continuously high […] At that time, the chief cabinet secretary, Mr Edano, told the Japanese people that there would be no immediate harm to their health.”
  • “Although three months have passed since the accident already, why have even such simple things [like implementing a strong response geared towards measuring radioactivity in food] have not been done yet? […] I get very angry and fly into a rage.”
  • “Radiation has a high risk to embryos in pregnant women, juveniles, and highly proliferative cells of people of growing ages. Even for adults, highly proliferative cells, such as hairs, blood, and intestinal epithelium cells, are sensitive to radiation.”

    Have I told you lately I love YOU ENENEWS?!?
    I do! TY!

    From the article: ““We had rain in Tokyo on March 21 and radiation increased to .2 microsieverts/hour and, since then, the level has been continuously high….”

    0.2 microsieverts per hour is high? The radiation in Los Angeles is always higher than that.

    All over the US, the CPM, converted to microsieverts, is higher than that.

    Now I’m confused about what is “high” radiation. I am not trying to make a pro-nuke point here. Just wondering.

      @bob hardin
      0.2 mcsievert/hr is within the normal range…for instance the outskirts of london with no large rock mass will give of 0.3 to 1.5 mcsievert/hr! moving into mountains will give you higher radon readings and higher gieger readings as bacckground! hope i got that right and hope it helps!

    I’m a piping engineer who has worked in the Petro-chemo industry for years. I’m still a practicing Professional Engineer. When I first started designing piping systems, I used charts and tables to design piping. Locating supports, loops and estimating structural loads was more of an art than science. There was no software to design piping. The first step in the evolutionary process of software development was a program called MARE ISLAND. This program was developed by the US Navy to design piping on nuclear submarines. Back then everything was done by key punch card and I will tell you it was a nightmare to model a piping system using MARE ISLAND. I believe the program would do a thermal and weight analysis but that was all. Then programs such as Triflex and Dynaflex came along where thermal, weight, and operating cases could be analyzed. Still the software used key punch cards but had a free format feature which eased the pain somewhat. As the years rolled on the wind loadings and probably sometime in the late 80’s the software finally could do earthquake loading. Caesar II and Autopipe became a very sophisticated tool for analyzing piping. The the desk top computer revolutionized the industry. Had these programs been around when these plants where built we probably would not be talking about this now. To the younger generation who have cut their teeth on computers it is inconceivable that these plants could be design by hand calculations.
    Piping in old nuclear plants was done by hand. I know because I was there at the time of the software development. The engineers used charts and relied heavily on their experience. This was acceptable because at the time earthquake and wind loading on a piping system was not what it is today.
    Also in the early days snubbers and other sophisticated hardware to protect a piping system did not exist. I think what has happened at Fukushima is that the piping was done in a day when the loadings were nowhere near what they are today. Also , the piping was done by hand. TEPCO should have re-analyzed all of the existing piping using the sophisticated software and redesigned the piping for the more violent conditions we have today. I’m speculating here but I doubt that Tepco did any of this. To these tight wads it would have been too costly. This plant was accident waiting for a place to happen. The engineers of old would not have been able by hand to calculate the loading required today. The engineers of old would not have anticipated earthquakes at the magnitude they are occurring today.
    The old building codes and piping codes did not even attempt to define a procedure for earthquake loading. Today it is very specific. These old plants should have been re-evaluated from the ground up as a new plant.

      You submit a unique angle to the safety of the original design of those early Mark 1 BWR’s. Information shows that Tepco did upgrade some critical systems, just not enough. All extreme factors were not accounted for and I’m sure the economic factor had great weight in deciding what systems and how much to upgrade.


      There are so many factors to consider and these plants become more and more complicated with every back up system installed. The studies have been made.

      Recommendations for Revision of Seismic
      Damping Values in Regulatory Guide 1.61


      But they are just studies and recomendations. They are not binding rules and the regulatory process is weighted in the builders and operators favor financially. The people have no real say in the upgrade and design process review.
      There is always more to consider when it comes to the effect that mother nature can produce. The biggest factor is the site location. not just geographically but the actual soil material that they sit on.

      New seismic design spectra for nuclear power plants


      And even then the end result is not predictable with the largest unknown that is impossible to account for or calculate. Mother nature, a dynamic, changing, moving target that man has yet to understand, even in the simplest of context.


      We are not wise enough to look into the future and determine what the end result of our best laid plans will be…

      Thx for the history on old/newer design piping !

      Jebus & jackassrig…

      This is exactly my point when I say that capitalism and nuclearism cannot mix. They are antithetical.

      It is always how can we get our product to market with the utmost speed, before the competitors, with the lowest cost overhead! This way of doing business, this attitude, is anathema to handling nuclear fission/fusion with the respect it absolutely requires.

      Either nuclearism will compell us to a new level of ethical consciousness, or…that’s all she wrote, folks, on this little experiment called homosapiens.

    this is WAY TOO HOT not to repost:

    ten trillion becquerels per hour

    ok… the earth is 196940000 square miles…
    lets cut that in half for the northern hemisphere.
    98,470,000… and that is close enough to 100,000,000.

    so, ten trillion divided by 100,000,000 square miles is 100,000 becquerels per square mile per hour for the northern hemisphere. (do not forget per hour)

    24 hours per day
    = 2,400,000 becquerels per day per square mile of northern hemisphere.

    7 days a week
    = 16,800,000 becquerels per week per square mile of northern hemisphere.

    365 days in a year
    = 876,000,000 becquerels per year per square mile of northern hemisphere.

    makes you feel…?
    comments… anyone?

    • larry-andrew-nils

      that’s 300 bequerels per year per square yard of northern hemisphere !

      that’s my breathing space !

      • larry-andrew-nils

        the average persons yard is about 1000 square yards, so we each get 300,000 bequerels of hot particles in our yard after one year and each year afterward…

        what does this mean?… is it as dangerous as it sounds? please help me.

        • Dr. Anne Lee Tomlinson Maziar anne

          For one thing, the hot particles land and concentrate in hot spots. Not every square foot on the planet will get the same amount. Rain causes the hot particles in the atmosphere to come down to the earth. The jagged edges of snow and ice attaches more hot particles than anything. There are going to be more hot particles depending on how close the location is the melted reactors. A lot depends on the jet stream, and on previous fallout from previous accidents and nuclear testing.

          “More than a month’s rain falls on parts of UK in just six hours *PICS*
          LONDON — Flash floods caused chaos yesterday as a fortnight’s rain fell in just half an hour in some areas.”

          the rain didnt fall to hard in london,
          but i did a wet swipe and got 0.22 mcsievert/hr the dry background was 0.1 mcsievert and today, in the sun i got a “dry” reading spiking 2.9 but averaging 1.9 mcsievert. maybe due to evaporation of ground moisture…seems that the levels are low but the rainwater is hot slightly, i should say detectable….thank you soueks das vidania!!
          i suspect the lichen and mushroom bioaccumulation will be occouring on at least some level 🙁

      Way past time for “Operation Plowshare”.

      • arclight arclight

        i presume you ment this fine bunch nova
        The Plowshares Movement is an anti-nuclear weapons movement that gained notoriety in the early 1980s when several members damaged government property and were subsequently convicted.

        Other actions followed. As of 2000, some 71 such actions happened on several continents, sharing these elements: 1. absolutely nonviolent to people, 2. each actor claimed personal responsibility for her or his actions, never fleeing the scene but rather standing accountable, 3. making some effort, big or small, real or symbolic, to turn swords into plowshares. There have been several more such actions in the new millennium. Over the years, some of these have resulted in acquittals and the vast majority end in prison time for the actors, the longest of which were those meted out to the 1984 group, the Silo Pruning Hooks (after the Biblical verse admonishing people to turn swords into plowshares and spears into pruning hooks—both Micah and Isaiah), two of whom earned 18 years in federal prison. The “swords” have included live nuclear weapons, components of the nuclear arsenal, and even armed forces personal field weapons.

    I am worried, that’s all I can say. It seems like things can only get worse from here, and the onslaught of radiation is not going away…if anything it is increasing.

      What I remember from one estimate: 429 hot particles for every living person on the planet. And still increasing.

        Fukushima Equals 3,000 Billion Lethal Doses
        Dr. Michio Kaku pointed out on CNN March 18, 2011, Chernobyl involved one reactor and only 57.6 Tons of the reactor core went into the atmosphere. In dramatic contrast, the Fukushima Daiichi disaster immediately involved six reactors and IAEA (International Atomic Energy Agency, a UN Agency) documented 2,800 Tons of highly radioactive old reactor cores.
        Looking at the current Japanese meltdown as more than 50 Chernobyls is one way some people are beginning to estimate the disaster. Simple division tells us there are at least 48.6 Chernobyls in the burning old reactor cores pumping fiery isotopes into the Earth’s atmosphere. Some are calculating that this all adds up to three thousand billion (3,000,000,000,000) Lethal Doses of Radiation means there are 429 Lethal Doses chasing each and every one of us on the planet, to put it in a nutshell.
        “Those who deny or deceptively play down the catastrophic threats to public health from all phases of the nuclear power cycle, from mining to the lack of any proven solution to permanent and safe disposal of very long-term deadly spent nuclear fuel, recklessly ignore the medical/scientific lessons we should have learned from current and previous nuclear accidents,” writes Rudi H. Nussbaum who is a Professor emeritus of Physics and Environmental Sciences at Portland State University

        • larry-andrew-nils

          three thousand billion lethal doses divided by one hundred million square miles (northern hemisphere)

          equals: 30,000 lethal doses per square mile of northern hemisphere.

          that’s one lethal dose for every 10 square yards.

          10 square yards is your bedroom.

          good night.

          damn, i didn’t mean to come off that hard, but, you do the math.

          • westcoastgirl westcoastgirl

            This number is, of course, only the case if every bit of nuclear fuel from all six reactors is released into the atmosphere, which HOPEFULLY will not happen.

            Unless Tepco feels the need to evacuate for their own personal safety…

            I think there are a lot a variables. I lived 15 miles from Santa Susana and I’m still alive. However, I live on an extremely restricted diet and I avoid a lot of electromagnetic fields and microwaves.
            Santa Susana Field Laboratory
            “This page is dedicated to the victims of the Santa Susana Field Laboratory. I am currently filming a documentary based on the Nuclear Disaster that occurred there in 1959 along with the improper disposal of millions of gallons of toxic chemicals.

            “This Documentary is set to be the voice of hundreds of people who’s lives were changed by the Hidden Secrets of “THE SANTA SUSANA FIELD LABORATORY” located in the hills between Simi Valley California and the San Fernando Valley. Also known as “Rocketdyne ” this facility with the help of the United States Government covered up the largest nuclear disaster to ever take place on United States soil. Experts say 200 times worse than the highly publicized “Three Mile Island” incident.”


            Santa Susana Field Laboratory
            “Throughout the years, approximately ten low-power nuclear reactors operated at SSFL, in addition to several “critical facilities”: a sodium burn pit in which sodium-coated objects were burned in an open pit; a plutonium fuel fabrication facility; a uranium carbide fuel fabrication facility; and the purportedly largest “Hot Lab” facility in the United States at the time.[citation needed] (A Hot Lab is a facility used for remotely cutting up irradiated nuclear fuel.) Irradiated nuclear fuel from other Atomic Energy Commission (AEC) and Department of Energy (DOE) facilities from around the country were shipped to SSFL to be decladded and examined.
            “The Hot Lab suffered a number of fires involving radioactive materials. For example, in 1957, a fire in the Hot Cell “got out of control and … massive contamination” resulted. (see: NAA-SR-1941, Sodium Graphite Reactor, Quarterly Progress Report, January–March 1957). In July, 1959, the site suffered a partial nuclear meltdown that has been named “the worst in U.S. history”, releasing an undisclosed amount of radiation, but thought to be much more than the Three Mile Island disaster in 1979.[21] Another radioactive fire occurred in 1971, involving combustible primary reactor coolant (NaK) contaminated with mixed fission products.[22][23]
            “At least four of the ten nuclear reactors suffered accidents. The AE6 reactor experienced a release of fission gases in March 1959, the SRE experienced a power excursion and partial meltdown in July 1959; the SNAP8ER in 1964 experienced damage to 80% of its fuel; and the SNAP8DR in 1969 experienced similar damage to one-third of its fuel.[24]
            “The reactors located on the grounds of SSFL were considered experimental, and therefore had no containment structures. Reactors and highly radioactive components were housed without the large concrete domes that surround modern power reactors.”

            Is the number for Chernobyl based on what was released actually or potentially? I thought that there are still releases from Chernobyl 25 years later.

        More Radiation Stuff – Hot Particles
        I touched on hot particles previously. They are still somewhat in the news with the west coast of the US testing for up to 5 hot particles per day estimated per person.

        A hot particle is a microscopic bit of a radioactive substance. The size of the particle can range from a few nanometers (a billionth of a meter) to a few micrometers (millionths of a meter). An atom of Cesium-137 has a diameter of about 0.4 nanometers. So a molecule of Cesium-137 oxide or whatever it happens to react with would be a little larger. For the sake of simplicity, let’s say 1 nanometer since the particle may contain a little of something else.

        Then a hot particle of Cesium-137 will contain anywhere from a few hundred Cesium-137 atoms to a few hundred thousand. For simplicity, let’s say 100,000.

        With a half life of 30 years, there would be 50,000 decays in 30 years, around 1700 decays per year, about 5 decays per day, per hot particle. With the bad luck of inhaling all 5 hot particles per day, that would be about 1 decay per hour. So if your bad luck continues, in sixty days you would add 60 decays per hour or 1/60 Becquerel to your radiation exposure. Becquerel is defined as decays per second.

        Cesium-137 is convenient since it makes up the bulk of the radiation fallout. If the Hot Particle was Plutonium-239 with a half life of 24000 years, the decays would be 30/24,000 times 1 Becquerel. Roughly of course, since the diameters are a little different, but not much.

        Based on food radiation limits, about 500 Becquerel per kilogram is safe, so to add the health impact of supposedly safe food day of meals, every sixty days you add one Becquerel so in 82 years you have accumulated 500 Becquerels of radiation from hot particles if you are unlucky enough to inhale all five hot particles per day of a Cesium-137 compound for 82 years.

        Update: I used CPM instead of CPS, but you should still get the idea.

        Wow! That sounds pretty dangerous to me! So if you plan on living to be 240, I would be scared shitless.

        During the atmospheric nuclear testing age, there were a lot of hot particles. Chernobyl produced lots of hot particles. How much health impact have those hot particles had on cancer rates? Not a whole hellava lot since most folks don’t live past 80 years. Do you think maybe that the hot particle press releases might be a little sensationalized?

    When the doctor says “it’s been three months since the accident”, it means this news is 2 months old.
    Doesn’t make it better, but it’s not as if he stated that TODAY.
