Another man died of acute lymphocytic leukemia [27Nov11] - 0 views

  • A 23 years old man died of acute lymphocytic leukemia as well. Mr. Abe Hiroto wrote columns for a fisher’s magazine, called “Rod & Reel”.
  • His grandfather was from Fukushima. To support Fukushima by eating Fukushima fish, he was living in 30 km area, lived on fish from river or sea. He is featured on Rod & Reel, Januaryissue, sold on 11/26. Related post Acute lymphatic leukemia news caster Otsuka may die in 5 years for 70% (Source)(Source)

19.0 micro Sv/h in Shinagawa, Tokyo due to burning? [24Nov11] - 0 views

  • This unusually high level of radiation is suspected to be related to incineration ash of radioactive debris,which started to coming from Iwate to Tokyo.http://fukushima-diary.com/2011/11/breaking-news-radioactive-debris-arrived-at-tokyo/ Radioactive debris is supposed to be burnt at Tokyo Waterfront Recycle Power, which is a group company of Tepco.
  • By accepting radioactive debris to Tokyo, Tepco makes money again. A journalist who asked about this “transaction” at Tepco’s press conference was banned to attend at the conference anymore by Mr.Terasawa, Tepco’s spokesman.
  • The smoke and incineration ash are suspected to be highly radioactive to cause secondary exposure to all around in Japan.

  • As a mater of fact, there is no proper filter in the facility of Tokyo Waterfront Recycle Power. They only have bug filter, which is useless to clean radioactive material. (Source) When the debris arrived at Tokyo, it people were banned to measure radiation around the container. Because of the wind from North, and this smoke from Tokyo Waterfront Recycle Power will contaminate Tokyo again.

Breaking News: Recriticality may be happening continuously [01Oct11] - 0 views

  • In addition to two previous posts on this issue:”Fukushima went back to recriticality almost for 100%” and “Fukushima in recriticality” it turns out that they also detected I-131 in North and Western Japan. 1) in Miyagi. 42 Bq/kg – 8/9/2011 41 Bq/kg – 9/6/2011 2) In Nagasaki 563 Bq/kg – 8/4/2011 151 Bq/kg – 8/11/2011 44 Bq/kg – 8/22/2011
  • When it comes to the detection of I-131, some people always try to deny the possibility of recriticality to reassure themselves by bringing up the possibility of medical usage of Iodine. However, in a previous post, Breaking News: Fukushima went back to recriticality almost for 100%, the possibility of the medical usage of Iodine was completely denied by asking the local hospitals. From all the data,it is possible to think Fukushima still goes into the state of recriticality on and off http://onodekita.sblo.jp/article/48003171.html Kuri Sewage Odei 20110906

Leaked TEPCO report: 120 billion Becquerels of plutonium, 7.6 trillion Becquerels of ne... - 0 views

  • Yokohama, Oct. 15 — Mochizuki of the Fukushima Diary website is reporting on a June 2011 document that has been “leaked on the internet” which reveals that Plutonium-238, -239, -240, and -241 were released “to the air” from Fukushima Daiichi during the first 100 hours after the earthquake. The amount of plutonium released is said to be 120 billion Becquerels. It also states there was a release of 7.6 trillion Becquerels of Neptunium-239. Mochizuki says this report was made by Tepco for a press conference on June 6 and the media knew and “kept concealing the risk for 7 months and kept people exposed”.

Fukushima local government only check 2.9% of all the rice [07Dec11] - 0 views

  • Following up this article http://fukushima-diary.com/2011/11/russian-roulette/ Though it is obvious that Fukushima rice is contaminated ,Fukushima government has been trying to sell their cesium rice whatever happens. Every time Fukushima rice exceed the emergency safety limit ,Fukushima local government re-declared “safety” with zero basis and tried to push their cesium rice to the market. They say,they sell only rice which have passed their safety test. However,it turned out that they only check 2.9% of all the rice. There are 60,000 farmers in Fukushima ,but Fukushima local government only checked 1724 lots of rice. but they state it is more than double as what the government required them to check ,other local governments conduct even more meaningless safety check. Additionally ,even around Onami chiku ,where they measured 1270 Bq/kg from the rice , they check only one of 50 bags,which means 2 %.

Actual Fukushima worker talks ,water purifying system has never worked [06Dec11] - 0 views

  • Following up this article http://fukushima-diary.com/2011/12/220t-of-highly-radioactive-water-leaked-and-a-part-of-it-leaked-to-the-sea/ The water purifying system has never worked properly. It was urgently constructed , the whole system can’t stand anymore. These are the tweets of actual Fukushima worker ,Happy20790. He explains how it is on the sight.
  • <Translation> The contaminated water leaks a lot recently. This time ,it went out of the “building” so it was reported but actually it happens frequently. I called it “a building” ,but it’s actually a temporary tent on a temporary concrete basement. It leaked from the first operation ,so they made a tiny dam in it. Maybe it’s only 20cm high. I don’t get into the tent recently because it’s too radioactive,but I used to pump up leaked contaminated water. The contaminated water emits a lot of beta ray ,so you need to be careful. This time ,Tepco’s spokes man said it was 110mSv/h ,but it is higher at some points. The concrete basement was constructed really urgently. They built the tent even before the concrete dried. so it got cracked already. Other tent may have the same problems too. Unlike our ordinary contract ,makers only set the facility ,they don’t take responsibility of handing or maintenance. As I tweeted before,this water purifying system is not a long-lasting system. It is a temporary system without proper planning process. In order to release cooling water to the sea ,we must install more proper facility. Now the gutter is straightly connected to the sea. They must be shut down or a dam must be made. Currently every time it rains, radiation on the ground and radiation stuck to the plants flow into the sea straightly. Makers and workers are already withdrawing from Fukushima plants ,but Tepco has no long term plan. They need to predict the future risk and prevent it from happening in advance.

Dr. Koide from Kyoto uni "Tepco's assumption is baseless" [[01Dec11] - 0 views

  • On the radio program, “Tanemaki journal” on MBS, Dr. Koide from Kyoto University stated that Tepco’s assumption to tell there is still 37 cm to go has no basis. Dr. Koide has been warning melt-out since May, yet he admitted that he can not assume where the melted fuel is now because human-beings have never gone through such a crisis. He estimates the melted fuel may stop about 5~10 meters deep under ground because melted fuel becomes larger as it contains concrete, the body of container vessel etc. It starts from 2800C, but the heat will decrease gradually.

Reactor 4 : Spent fuel pool was boiling without water after 1/1/2012 [08Jan12] - 0 views

  • Following up this article about the decreasing of water level at reactor 4… The blogger woman in Minamisoma leaked information from an actual Fukushima worker. According to her post, after the earthquake of 1/1/2012, the pipe of spent fuel pool for reactor 4 was broken, the pool completely lost its water. The worker stated, Sooner or later, the truth will have to to be widely known. Believe it or not, you will only regret. Wear a mask at least. The pool was boiling without water.

Fukushima worker confesses "There is nothing left that we could do"[24Nov11] - 0 views

  • This Fukushima worker (Twitter account Happy20790) tweets useful information daily. On 3/11, he was right at the plant, had water of the spent fuel pool over his protecting clothes. When reactor 3 exploded, he was in reactor 2. Though his tweets are sometimes biased, he basically tries to be neutral. Remember the previous post “Tepco reduced 60% of the sub contract workers at Fukushima plants” He explained the truth behind it all.
  • In short, he says Tepco started reducing the number of workers because they can not do anything for the reactors anymore. Even though they stock lots of workers, there is no clue to do something most important. He explains, the next thing to do is to check the state of container vessels pressure vessels, define the actual point of the leakage of contaminated water, and action to stop the leakage, but there is zero plan / idea how to manage it. The interiors of the buildings are extremely radioactive and nobody can officially go into reactor 3 (though the helmet of the worker was recorded in the video taken by the robot). They can never go into the basement floor of the reactors either. The only thing they can do is to analyze the gas from inside of the container vessels. Thus nothing can be done by human anymore. They can only clean debris, take away broken operation floor, maintain the water purifying system, setting new tanks etc..

The yellow powder might be plutonium [25Sep11] - 0 views

  • About the previous post http://fukushima-diary.com/2011/09/news-japan-after-the-typhoon/ I received a message from a reader of this blog. It was to suggest the yellow powder could be plutonium. Here is the explanation. http://sti.srs.gov/fulltext/ms2002705/ms2002705.html source for text below
  • Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor. The physical properties of plutonium metal are summarized in Table 1.
  • Only two plutonium isotopes have commercial and military applications. Plutonium-238, which is made in nuclear reactors from neptunium-237, is used to make compact thermoelectric generators; plutonium-239 is used for nuclear weapons and for energy; plutonium-241, although fissile, (see next paragraph) is impractical both as a nuclear fuel and a material for nuclear warheads. Some of the reasons are far higher cost , shorter half-life, and higher radioactivity than plutonium-239. Isotopes of plutonium with mass numbers 240 through 242 are made along with plutonium-239 in nuclear reactors, but they are contaminants with no commercial applications. In this fact sheet we focus on civilian and military plutonium (which are interchangeable in practice–see Table 5), which consist mainly of plutonium-239 mixed with varying amounts of other isotopes, notably plutonium-240, -241, and -242.
  • ...9 more annotations...
  • Plutonium belongs to the class of elements called transuranic elements whose atomic number is higher than 92, the atomic number of uranium. Essentially all transuranic materials in existence are manmade. The atomic number of plutonium is 94. Plutonium has 15 isotopes with mass numbers ranging from 232 to 246. Isotopes of the same element have the same number of protons in their nuclei but differ by the number of neutrons. Since the chemical characteristics of an element are governed by the number of protons in the nucleus, which equals the number of electrons when the atom is electrically neutral (the usual elemental form at room temperature), all isotopes have nearly the same chemical characteristics. This means that in most cases it is very difficult to separate isotopes from each other by chemical techniques.
  • Plutonium-239 and plutonium-241 are fissile materials. This means that they can be split by both slow (ideally zero-energy) and fast neutrons into two new nuclei (with the concomitant release of energy) and more neutrons. Each fission of plutonium-239 resulting from a slow neutron absorption results in the production of a little more than two neutrons on the average. If at least one of these neutrons, on average, splits another plutonium nucleus, a sustained chain reaction is achieved.
  • The even isotopes, plutonium-238, -240, and -242 are not fissile but yet are fissionable–that is, they can only be split by high energy neutrons. Generally, fissionable but non-fissile isotopes cannot sustain chain reactions; plutonium-240 is an exception to that rule. The minimum amount of material necessary to sustain a chain reaction is called the critical mass. A supercritical mass is bigger than a critical mass, and is capable of achieving a growing chain reaction where the amount of energy released increases with time.
  • The amount of material necessary to achieve a critical mass depends on the geometry and the density of the material, among other factors. The critical mass of a bare sphere of plutonium-239 metal is about 10 kilograms. It can be considerably lowered in various ways. The amount of plutonium used in fission weapons is in the 3 to 5 kilograms range. According to a recent Natural Resources Defense Council report (1), nuclear weapons with a destructive power of 1 kiloton can be built with as little as 1 kilogram of weapon grade plutonium(2). The smallest theoretical critical mass of plutonium-239 is only a few hundred grams.
  • In contrast to nuclear weapons, nuclear reactors are designed to release energy in a sustained fashion over a long period of time. This means that the chain reaction must be controlled–that is, the number of neutrons produced needs to equal the number of neutrons absorbed. This balance is achieved by ensuring that each fission produces exactly one other fission. All isotopes of plutonium are radioactive, but they have widely varying half-lives. The half-life is the time it takes for half the atoms of an element to decay. For instance, plutonium-239 has a half-life of 24, 110 years while plutonium-241 has a half-life of 14.4 years. The various isotopes also have different principal decay modes. The isotopes present in commercial or military plutonium-239 are plutonium-240, -241, and -242. Table 2 shows a summary of the radiological properties of five plutonium isotopes. The isotopes of plutonium that are relevant to the nuclear and commercial industries decay by the emission of alpha particles, beta particles, or spontaneous fission. Gamma radiation, which is penetrating electromagnetic radiation, is often associated with alpha and beta decays.
  • Table 3 describes the chemical properties of plutonium in air. These properties are important because they affect the safety of storage and of operation during processing of plutonium. The oxidation of plutonium represents a health hazard since the resulting stable compound, plutonium dioxide is in particulate form that can be easily inhaled. It tends to stay in the lungs for long periods, and is also transported to other parts of the body. Ingestion of plutonium is considerably less dangerous since very little is absorbed while the rest passes through the digestive system.
  • Plutonium-239 is formed in both civilian and military reactors from uranium-238. The subsequent absorption of a neutron by plutonium-239 results in the formation of plutonium-240. Absorption of another neutron by plutonium-240 yields plutonium-241. The higher isotopes are formed in the same way. Since plutonium-239 is the first in a string of plutonium isotopes created from uranium-238 in a reactor, the longer a sample of uranium-238 is irradiated, the greater the percentage of heavier isotopes. Plutonium must be chemically separated from the fission products and remaining uranium in the irradiated reactor fuel. This chemical separation is called reprocessing. Fuel in power reactors is irradiated for longer periods at higher power levels, called high “burn-up”, because it is fuel irradiation that generates the heat required for power production. If the goal is production of plutonium for military purposes then the “burn-up” is kept low so that the plutonium-239 produced is as pure as possible, that is, the formationo of the higher isotopes, particularly plutonium-240, is kept to a minimum. Plutonium has been classified into grades by the US DOE (Department of Energy) as shown in Table 5.
  • It is important to remember that this classification of plutonium according to grades is somewhat arbitrary. For example, although “fuel grade” and “reactor grade” are less suitable as weapons material than “weapon grade” plutonium, they can also be made into a nuclear weapon, although the yields are less predictable because of unwanted neutrons from spontaneous fission. The ability of countries to build nuclear arsenals from reactor grade plutonium is not just a theoretical construct. It is a proven fact. During a June 27, 1994 press conference, Secretary of Energy Hazel O’Leary revealed that in 1962 the United States conducted a successful test with “reactor grade” plutonium. All grades of plutonium can be used as weapons of radiological warfare which involve weapons that disperse radioactivity without a nuclear explosion.

It can vary in color from yellow to olive green, depending on the particle size, temperature and method of production.[1]

Plants are dying [06Oct11] - 0 views

  • In the previous post Column of the Day: brine damage? I reported evergreen plants are dying for some reason. Today, the actual Fukushima worker, Happy20790 tweeted a similar thing. Happy20790
  • Back in April, one of my followers asked me if any trees are dead and turned to be brown around the plants. I checked the tree at that time and it was green, at least at that time. I don’t know when it went dead. It’s not the whole tree but a part of it though..well it’s likely to be radiation..

Why Japanese government conceals |[14Oct11] - 0 views

  • They found strontium at two more different places in Yokohama. Now they have measured strontium at three places in Total. All of them are located just around the corner from my apartment. It’s possibility that strontium is already everywhere around in Tokyo. I went to Tokyo last weekend. I visited Foreign Correspondents’ Club of Japan to have a pre-interview. The interviewees have worked for National Geographic or Jiji , They have done great reports about Sarin terrorism and the Tokai village nuclear accident. They met me because they were interested in my idea of “radiation refugees”.
  • They kindly offered me to help set up a new visa of “radiation refugee” in EU. For the further interview, they are planning to meet me this Sunday again. I need to clean my room before. In the interview, they asked me what I think must be done. I answered all honestly. I answered: I think all the Japanese must evacuate to Australia at the closest. Then South Korean, Philippine people, Malay, Singaporian, Indonesian, West Coast, they all must evacuate and leave Japan empty except for pro-nuc mental cases.
  • UN, American army, etc will all have to build the front line of the radiation shield on the Japan island, to minimize the potential international risk. No wonder Japanese race will lose their land. We will have to live like old Jewish. (Nika here – Iori refers to the millennia long Jewish Diaspora) We can no longer eat sushi. All the Pacific Ocean will keep being contaminated until human-beings invent a technology to pick up melted nuclear fuel rods from miles deep in the ground. Sure, the reporter called me unrealistic. It even seems so to me. However, I can not find any reason to deny it. On the other hand, the Japanese government is so eager to conceal the fact. US government seems to be helping it too. Why?

  • It is also the core problem of this whole disaster. The actual problem, which is as serious as radioactive contamination, is where to move the 30 million people from around Tokyo. By counting all the rest of the Japanese and Asian people, the number will be billions. Where to move them? This is the core of the problem. “Radiation refugee” The countries to accept them are seriously needed. We can never go back to before 3-10-11. World has totally changed. We must accept the fact.

Bloody sneeze [31Oct11] - 0 views

  • As an actual Fukushima worker warned one month ago,they are finally recognizing pollen may be the biggest menace for internal exposure. Pollen directly gets into your lungs,nostrils,and all around in your body. It causes severe internal exposure. Japanese Forestry Agency has finally started evaluating the risk but it seems too late. Annually,pollen starts flying from December. Because this is the first thing that’s ever happened to human-beings,there is no solid study. However,according to the research conducted in last June by Ministry of Education, Culture, Sports, Science and Technology,Japanese cedar leaves contained 177,600 Bq/Kg at that time.
  • Considering that there has been more fallout since last June,the radiation level may be even higher. 1850km2 (The entire area of Tokyo is 2187km2) area of Fukushima is covered with Japanese cedars. The pollen flies further than hundreds of km ,(Tokyo is about 220km away from Fukushima plant) ,Tokyo is obviously in the firing range. Contamination in the mountain / forrest area is also serious because they can never decontaminate it. When you sneeze,it may be already too late.
