On 2012 March 19, The Asahi Shimbun reported that the “city of Osaka, the largest shareholder of Kansai Electric Power Co., will call on the utility to abolish all of its reactors “at the earliest possible time” and today, Mainichi Daily News commented that Osaka had “stirred ripples”. Articles are reproduced below. Osaka Mayor Toru Hashimoto’s suggestion to phase out of nuclear power, surely surprised KEPCO investors but also citizens for its unusual thoughtfulness.

Kansai is the western region of Japan where Osaka, Kobe, Kyoto, Nara cities lie and, depending on definition, the nuclear power plant shore-lined prefecture of Fukui, where a 7.3 magnitude earthquake killed 1% of population and completely damaged 79% of buildings in 1948. Besides, prevalent winds blow from Fukui towards the huge drinking water Biwako reservoir and aforementioned Kansai cities. Under the radioactive fallout in case of such an earthquake would also be prefectures of Gifu and Aichi, an industrial heartland centered on Nagoya city, where Toyota, Mitsubishi Heavy Industries and Toray Industries (worldwide leader in the carbon fiber industry that should make Boeing Dreamliner fly someday) are based. A new powerful earthquake in Fukui would probably relegate Japan a few ladders down the economic rankings. Kansai is already under severe economic stress – it always was but for a brief decade of national euphoria called the “bubble”.

Since about 30 years ago, poor Japanese regions exchanged time and again their votes and security against subventions and nuclear power plants. Whenever subventions would dry up, they would agree for a new reactor building. Nowadays that these are idled and that subventions have run out, poor regions cannot start a new cycle and are pushing and being pulled to ramp up their radioactive waste “management” business. In the same vote buyout scheme as for nuclear power plants, over-sized incinerator plants have been built and left unused due to their capacity threshold being over the actual amount of waste. Poor prefectures now plan to upgrade these little used, dioxin-spitting facilities so that they could operate at a wider range of waste quantities and include some kind of filtering for radiation. This scheme represents a large economic boost promise in terms of construction work, which is the main employment outside large cities – and under the control of yakuza gangs, who request some sustained business to replace the drop in their recruiting services for nuclear plant workers.

Radioactive waste are largely above what is considered as “low-level waste” worldwide and its incineration in current facilities turn their prefecture into secondary radioactive sources, the primary being Fukushima, still emitting as of 2012 March 22, a year after. Current secondary radioactive sources include 23 wards in Tokyo, Tomakomai (Hokkaido) and Shimada (Shizuoka, where Japanese green tea comes from).

Many prefectures have requested to become secondary radioactive sources, including places where the transportation hazard, time and cost had prevented the Japanese government to push for it such as Okinawa. However, Okinawa is surviving only by the presence of the US army and its underlying economy is threatened by a possible redeployment in Japan, in Guam or elsewhere. Tourism has been declining since about 5 years ago in Okinawa and will not pick up when it will effectively become a secondary radioactive source. Food in supermarkets in Okinawa come from all over Japan as it does not produce much besides beef which become labeled “Kobe” beef after spending 1 year in that heavily industrialized city. Okinawa cows are rather skinny so it must be quite a terrible feeding process that turn them into extra-fatty meat one year later in Kobe warehouses. There have been some scandals of radioactive wood used to bake pizzas in Okinawa, schools have been forced by parents to cancel radioactive snowball gifts, some vegetation like mosses from irradiated areas have been planted in Okinawa, etc. Okinawa is not a nuclear-free land anymore: this concept does not apply to any Japanese territory anymore one year after the disaster. As an advice to nuclear refugees from the no man’s land, if you cannot leave Japan, it is safer to settle down in cities where you can work to sustain a healthier lifestyle, not necessarily to the far end of the archipelago where they have no job; no sense about radio-protection; no clean food choice – and where you will be stuck when they start incinerating radioactive waste.

How does the new denuclearization scheme fit in with the irradiated waste incineration plan and is it for real? Kansai is searching for ways to revitalize its broken economy and incineration is one leg. The other leg is nuclear decommissioning, a potentially profitable business. It takes 5 years for nuclear combustible to cool down, under active controlled systems (or not so controlled systems). Then the proper decommissioning operations begin (and probably never really end). As an actual example, if we look at Sellafield in the UK, a mere 2 square mile facility, the official planning states that decommissioning and closure of the site is planned for 2120 (right: 108 years from now). After this stage, management of radioactive materials is forever. Therefore, decommissioning of the 3 reactors in Mihama, 4 in Oi and 4 in Takahama – and maybe Monju / Tsuruga – all in Fukui prefecture and globally called the Nuclear Ginza, could create a 300 years business, not including the storage and monitoring of million-year long radioactive waste. It could easily give a job to anyone and sustain the local economy. Additional benefits would come from the development of health care – did we mention that Osaka was a biotech center ?

Japanese pharmaceutical companies had trouble to compete globally because their drugs are not properly tested and have resulted in accidents and because they lack innovation. However, in the grand Osaka renewal scheme of joint radioactive waste incineration and nuclear decommissioning, there would be plenty of test subjects and Japan would have an incomparable lead in radiation-induced diseases, even though they would not be marketed as such: auto-immune diseases such as the Kawasaki syndrome, pneumonia, heart attacks, leukemia and all sorts of cancers, or any other kinds of affections described by Pr. Bandazhevsky, even in children (sic).

How is it that decommissioning would make the population sick? Nuclear reactor decommissioning is a task forecast to take over 1 century in the case of Sellafield but nuclear projects always get behind schedule (Areva EPR project in Finland as a relevant example). As a rule of thumb, you can at least double the time (in the case for Olkiluoto, Finland, Areva started in 2005, due to be completed in 4 years – now maybe in 9 years, probably 12) and since it is impossible to rule out wars, economic depressions, natural disasters and social unrest over the period of a century, it could take 4 to 500 years to carry out. The probability of the job being properly done to the end is marginal and our grandchildren, if they ever live, will most likely have to deal with no man’s lands in every place there used to be a nuclear power plant in the 20th century. Working in a nuclear power plant make people sick, they have in Japan, as well documented, not only in Fukushima. Work ethics are shoddy here and tasks are carried out by the 6th level of untrained sub-contractors aka yakuza firms. Nuclear Ginza and other locations in Japan like Tokaimura and Genkai accumulate accidents and are regularly leaking radioactive material, not surprisingly. Now let us project this over the next 500 years for a large segment of society busy cleaning a mess and adding to it at the same time: everyone would get sick, even if Hosono, Noda and Edano, the devilish Trinity as it were, were not working so hard to distribute contaminated food over all the territory – which they are. Mutations get transmitted to people who are not involved in the multi-generational task, weakening the whole society. As a side-note, it is of course impossible to decommission Fukushima nuclear plant within 40 years: it will never be really clean, no matter the official whitewash.

Recently 2 Japanese researchers apologized because they had taken some bone-marrow samples from cancer patients during surgical operations without anybody knowing: with radiation-induced diseases, all Japanese medical researchers would be able to experiment, publish their results and test new drugs on unsuspecting patients. When the Japanese war criminal in charge for human live dissection and experimentation during the war became the head of the top medical institute in Tokyo and was never bothered except for a moment by the Chinese woman who recognized him, anything can happen. Unit 731, Masaji Kitano and Green Cross all over again. Kansai, with Nuclear Ginza, you invested in a future treasure trove for your biotech and pharmaceutical industry (sic) ! Just as some people do not get black humor, let us note here that we are being sarcastic and we do not wish this nightmarish scenario to happen, quite the contrary but we are at a loss as to how prevent it. Japan has yet to come to term with its dark past and its present shows that it is never far behind – humor is a way to get some relief in the terrible situation we are now, and black humor can be offensive. Current Japanese politics are just as offensive.

So it could be for real and it would be the least damaging, as the alternative would be to wait until the next great Fukui earthquake and a fireworks over Nuclear Ginza.

Another possibility is that Hashimoto does not really intend to denuclearize Kansai, but is only trying to gain more KEPCO shares, some financial compensation or a special investor status from KEPCO for Osaka city in exchange for a time extension, a percentage increase in nuclear-produced electricity or such compromise.

Whichever, the pain only begins.


The Beer In Japan post on SurvivalJapan offered some advice on how to choose food products with minimal radiation exposure risk in an environment devoid of reliable information source, with beer as an example. Three months ago, my post titled Safer Food Quest warned about such Tokyo-headquartered dairy product companies as Meiji, which distributes milk of course, but also chocolate snacks, ice cream, etc. Warning eventually became a scandal – one in many to come in Japan criminal food industry – as reported by Bloomberg today (read the article below).

Bloomberg – Cesium in Meiji Milk Powder Spurs Recall Amid Radiation Threat

By Kanoko Matsuyama, Dec. 6

Radioactive cesium was found in milk powder made by a Meiji Holdings Co. unit, Kyodo News said, causing the shares to fall the most in eight months and raising concern that nuclear radiation is contaminating baby food.

Meiji, Japan’s largest supplier of infant formula, is voluntarily recalling 400,000 cans of its “Meiji Step” brand product, which may have been contaminated by radiation leaked from the Fukushima nuclear plant, Kyodo said today. Affected cans have 2012 expiration dates of Oct. 4, Oct. 21, Oct. 22. and Oct. 24, it said.

Levels of cesium found in the 850-gram cans of baby milk powder are within safe limits and pose no health risk, the Tokyo-based company said in a statement today. The product may have been contaminated by cesium in the air, it said. The product was made in Saitama prefecture, north of Tokyo , it said.

Prolonged exposure to radiation in the air, ground and food can cause leukemia and other cancers, according to the London- based World Nuclear Association. Japanese consumers have spurned certain food products, including beef, after evidence that fallout from Tokyo Electric Power Co. (9501)’s nuclear plant, crippled in the March 11 earthquake, entered the food chain.

Meiji fell as much as 13 percent in Tokyo trading, ending trading down 9.7 percent at a 30-month low of 3,020 yen. Rivals Morinaga Milk Industry Co. plunged 3.5 percent to a three-year low of 275 yen and Megmilk Snow Brand Co. declined 3.6 percent.

Cesium Traces

Traces of cesium-137 and cesium-134 were first detected in the Meiji milk product on Dec. 3 and were found again on Dec. 4, the company said today.

In a nuclear accident, radioactive isotopes including iodine-131 and cesium-137, which are normally contained inside the fuel rods, may be released into the atmosphere as gases or particulates if the rods are damaged. These can be inhaled or ingested through contaminated food or water. Children are especially susceptible to radiation poisoning from iodine, which can accumulate in the thyroid and cause cancer, according to the World Health Organization.

Cesium-137 that enters the body is distributed throughout the soft tissues, especially in muscle. Cesium-137 is eliminated faster from the body than other radionuclides, according to the U.S. Environmental Protection Agency.

Shoppers are becoming aware as the apparition of milk with certified unique origin from places out of the no man’s land suggest. For instance, milk ″from Hyogo prefecture only″ is now available in some supermarkets  (see picture below with red box added to mark this mention in Japanese). Previously, tainted Hokkaido milk was difficult to avoid – although the northern island east coast is regularly visited by plumes from Fukushima. Besides, milk origin is ambiguously labelled ″packaged in″ any given factories without any details about the actual origin of the milk itself, hence discreetly giving decision power over whether companies mixed healthy milk with radioactive waste. Of course, there isn’t any guarantee that milk marketed as originating from the monitored land does not come from cows just imported from the no man’s land. Premium Kobe beef, for instance, only needs to be raised one year in that crowded region to be legally labelled and sold and such – cows are generally raised in greener and cheaper places such as Miyazaki (Kyushu)or Ishigaki (Okinawa) and then sent to Kobe. Although moving is costly, the cost can be passed on more easily on Kobe beef eaters than on Hyogo milk drinkers, hence providing a relative security for the latter ones. However the price of safe milk will rise with along with its increasing scarcity and it may reach a level where moving “hot” cows for their milk make economic sense on the very short-term. Food industrials should take notice with the example of milk packers that it damages their image, equity and bottom line very rapidly though. (more…)

Nine months after the disaster, the Japanese Science Ministry finally gave birth to a report about radiation spread across Japan, as published by Asahi Shimbun newspaper (article also reproduced below). Although from the relatively small size of Japan compared to Chernobyl-stricken Belarus, it was obvious from the onset that Cesium would fall “all over Japan” (breaking news title from the Asahi Shimbun article), the issue was to assess concentrations.

Since the Japanese government policy remains to downplay the risk, after censoring radiation reports in the news and in the blogosphere, data should be taken with a grain of salt. Last week, the Japanese government has turned its back on the company it had contracted to monitor radiation in parks and school playgrounds around Fukushima, after it suddenly discovered that the accuracy of the Geiger counters it had ordered was substandard (Cf. Mainichi Shimbun news article and comment in Geiger Counter Case Study: Inspector Alert in SurvivalJapan). MEXT data for all regions but Fukushima falsely reported radiation levels close to natural background radiation for months so that I only trust citizens reports such as Safecast. On the Japanese government radiation map below, it is a safe bet to assign to each concentration the level range above each reported, i.e. for 0-10.000 Becquerel/sq.m, the real value is probably between 10.000 and 30.000 Becquerel/sq.m. As for the methodology, only one station per prefecture was used to measure data. The Japanese government and affiliated organizations reportedly used Geiger counters conveniently located to show the least radiation, as in the current case of Tokyo University, which use only their one station with lower readings and switched off the other one which measures higher levels of radioactivity. Japan is not the only country to set their radioactivity monitoring stations at their convenience, this is common practice as shown in France by CRIIRAD with Areva (ex-COGEMA) company for instance, in the context of nationwide contamination from closed uranium mines. Read for instance “Decommissioning Projects – France” on Wise-Uranium with links or directly the English report by Head of CRIIRAD Bruno Chareyron, “Radiological hazards from uranium mining”, available for download in PDF format. CRIIRAD stands for Commission de Recherche et d’Information Indépendantes sur la RADioactivité / Commission for Independent Research and Information about RADiation and Bruno Chareyron was invited in Fukushima.

If absolute figures are probably fudged, relative concentrations of radiation in cities are likely to be trustful (although it says nothing about other cities in each prefecture). Hereafter is a ranking based on the news article, with lowest concentration rounded up to 1 Bq/sq.m for Uto, Kumamoto Prefecture, as the reported value is unrealistically small (0.378 Bq/sq.m) and for the sake of having a non-null integer multiplier. It should be noted that the apparent precision of figures is misleading and I kept the 2 most significant figures for this short ranking:

Kumamoto (Kyushu) : 1

Osaka : 20

Tokyo : 20,000

Yamagata (Fukushima and Miyagi neighbor by the Sea of Japan) : 20,000

Ibaraki (northern neighbor of Tokyo by the Ocean Pacific) : 40,000

In other words, radiation is 10 times lower in Kyushu compared to Kansai (suspiciously, in spite of the Genkai nuclear incident, Cf. Nuclear Incident in Kyushu November Update on SurvivalJapan). Kansai is itself a 1000 times less irradiated than Tokyo. This seems about right and there is of course a gradient between these regions. Indeed, before information black-out was enforced, a Japanese green tea grower in Shizuoka (further south from Mount Fuji, about 150 km / 100 miles south-west of Tokyo) reported high level of radioactivity (read for instance the New York Post article about it). In order to get 680 Bq/kg in dried tea leaves, as was reported there in Honyama area, the soil needs to be pretty contaminated and hence also the air, from which radioactive fall-out precipitates (therefore, other food products from this wider area are contaminated as well). This means that statements like the following one is untrustworthy: “Large amounts of radioactive dust fell in Tokyo, but a separate survey has detected relatively low accumulations of cesium in the soil.” Actually, it was documented in the US in the wake of a nuclear bomb test in Nevada that decontamination of roads and concrete surfaces is impossible even by using hydrochloric acid, so if the latter sounds paradoxical with regards to “large amounts of radioactive dust fell in Tokyo”, then it is another lie by the ministry official : “Tokyo has smaller soil surfaces than other prefectures, but road and concrete surfaces are less prone to fixate cesium deposits, which were probably diffused by the wind and rain”. Read “Secret Fallout” by Dr. Ernest Stainglass available for download in PDF format for more information about the myth of nuclear decontamination and more specifically chapter 1, “Thunderstorm in Troy”.

Likewise, it is just simply impossible to reconcile statements of Ibaraki prefecture being 1 million times more radioactive than 2 years ago on one hand, and the current air radiation level being 0.14 uSv/h, i.e. what I personally measured in my city in the monitored area and which is an ordinary value indeed. Again, the same article mentions that Ibaraki is more than 40,000 times radioactive than Kumamoto in Kyushu (actually 100,000 if we consider the exact values given in the article). It is a wonder that such inconsistencies can exist in an article from a mainstream newspaper without a word of critical analysis. The article leaves a great grey area between Tokyo and Osaka – as it would be interesting to get some values for Nagoya for instance, which is inside the no man’s land in my book (although the Aichi prefecture is supposedly “clean” on the map below), as one needs to draw a line somewhere and radiation reports by citizens were higher than “normal” there.


Note: real values probably one notch higher in the scale

Asahi Shimbun – Cesium from Fukushima plant fell all over Japan

November 26, 2011

Radioactive substances from the crippled Fukushima No. 1 nuclear power plant have now been confirmed in all prefectures, including Uruma, Okinawa Prefecture, about 1,700 kilometers from the plant, according to the science ministry.

The ministry said it concluded the radioactive substances came from the stricken nuclear plant because, in all cases, they contained cesium-134, which has short half-life of two years.

Before the March 11 Great East Japan Earthquake, radioactive substance were barely detectable in most areas.

But the Ministry of Education, Culture, Sports, Science and Technology’s survey results released on Nov. 25 showed that fallout from the Fukushima plant has spread across Japan. The survey covered the cumulative densities of radioactive substances in dust that fell into receptacles during the four months from March through June.

Figures were not available for Miyagi and Fukushima prefectures, where the measurement equipment was rendered inoperable by the March 11 disaster.

One measurement station was used for each of the other 45 prefectures.

The highest combined cumulative density of radioactive cesium-134 and cesium-137 was found in Hitachinaka, Ibaraki Prefecture, at 40,801 becquerels per square meter. That was followed by 22,570 becquerels per square meter in Yamagata, the capital of Yamagata Prefecture, and 17,354 becquerels per square meter in Tokyo’s Shinjuku Ward.

The current air radiation level in Ibaraki Prefecture is about 0.14 microsievert per hour, equivalent to an annual dose of about 1 millisievert, the safety limit for exposure under normal time international standards.

Large amounts of radioactive dust fell in Tokyo, but a separate survey has detected relatively low accumulations of cesium in the soil.

“Tokyo has smaller soil surfaces than other prefectures, but road and concrete surfaces are less prone to fixate cesium deposits, which were probably diffused by the wind and rain,” a ministry official explained.

The fallout densities were considerably lower in the Chugoku and Kyushu regions in western Japan. The smallest figure of 0.378 becquerel per square meter came from Uto, Kumamoto Prefecture. The density in Osaka was 18.9 becquerels per square meter.

The peak value in Ibaraki Prefecture was 970,000 times larger than the cumulative fallout density of 0.042 becquerel per square meter in fiscal 2009, found in an earlier nationwide survey before the Fukushima crisis started.

Before the accident, cesium-137, which has a longer half-life of 30 years, had been detected from time to time from atmospheric nuclear tests. But those densities mostly stayed below 1 becquerel per square meter, while cesium-134, with a shorter half-life, was rarely detected, the ministry officials said.

Also on Nov. 25, the science ministry released maps of aerially measured radioactive cesium from the Fukushima plant that accumulated in Aomori, Ishikawa, Fukui and Aichi prefectures.

This was the final batch of the 22 prefectures in eastern Japan where mapping was to be completed by the end of this year.

Nowhere in the four prefectures did the accumulations exceed 10,000 becquerels per square meter, the threshold for defining an area as being affected by the nuclear accident. This reconfirmed the science ministry’s view that radioactive plumes wafted only as far west as the border of Gunma and Nagano prefectures and as far north as the border of Miyagi and Iwate prefectures, ministry officials said.

The ministry also confirmed that radioactive plumes tended to drift just short of mountain ranges where they formed belts of high cesium concentrations due to rainfall and other factors. The mountain ranges included the Ou and Iide mountains along the border of Yamagata and Fukushima prefectures, the Echigo mountains along the border of Fukushima and Niigata prefectures, the Shimotsuke mountains along the border of Fukushima and Tochigi prefectures, and the Kanto mountains along the border of Gunma and Nagano prefectures.

These patterns are shown in three-dimensional plots in an online Japanese-language document released by the science ministry (

The ministry also said Nov. 25 that it will conduct aerial measurements of cesium accumulations in soil in regions outside the 22 prefectures starting next year. That is because small amounts of cesium have been detected in dust deposits in Hokkaido and western Japan.


Beer is the favorite alcoholic beverage in Japan and this post offers advice on which brand and how to recognize the production area of your local beer in order to avoid drinking contaminated water (95% of the beverage on average) and rice, which is often included. Of the four major beer brewerers (Kirin, Asahi, Sapporo and Suntori), only one is headquartered outside the no man’s land (Suntori, in Osaka). Although Sapporo was historically from Hokkaido, it is not true anymore (and besides, Hokkaido is inside the no man’s land). Premium Yebisu beer belongs to Sapporo.

In you cannot afford imported beers, first advice is to go for Suntori for that reason. Besides, although nobody can prove that it is not just a PR operation, yet Suntori stated that they pay attention to the origin of ingredients and any risk of radiation. This is different from other companies who claim there is no danger, only “fear”. Furthermore, Suntory “The Premium Malt’s”  (cf. picture below taken from web for anonymity purpose), for instance, mentions (in Japanese) that hops is from Europe.


In our Japan Livability Map September 2011, we showed that the only remaining nuclear-free land in Japan is the Okinawa archipelago. It may be a tempting relocation strategy for expats who want to stay in Japan in safe conditions, and some Japanese have already made the move from Tokyo to save their children, as can be read in this WSJ article  and this one too. Recently, Shinsuke Shimada, a prominent show-business local figure embroidered in a mafia scandal is rumored to have moved in his holiday house there permanently. As a side note, Okinawa is famous in Japan as a refuge for law enforcement fugitives… There are two main issues to consider for expats looking down south, which are directly linked with the same in the rest of Japan:

1. Contaminated food

Okinawa is a tropical area so a lot of food is imported from mainland Japan. Although the main provider is relatively safe Kyushu island, itself being subtropical, some produce has to come from more temperate, albeit “hotter” parts of Japan. Besides, the free flow of food implies that some tainted ingredients will inevitably be mixed in factories all over the nation, like some great red wines are sometimes illegally cut with lower quality wines that producers need to get rid of, without most people noticing. Unless your diet is exclusively based on mango, goat liver noodle soup, bitter goya salad, “sea grapes” seaweed, premium local beef, Awamori (vodka-like local “sake”), etc., chances are that you’ll still ingest some irradiated food on the long-term. Ask yourself questions like how can you keep forever your kids from eating tainted ice-cream in a tropical island?

Expats usually enjoy a high living standard and candidates to Okinawa relocation will most probably need to resign from their current position and set up a low-profitability, high-risk business as local unemployment is high, level of living low and the economic sectors very focused and much less developed than in mainland. The lower living standard means that purchasing expensive, nuclear-free, imported food will become impossible for these new-comers. More about these consequences in issue no. 2 below.

2. Nuclear waste

Governments like to place dangerous sites away from the capital city where their offices and families reside. For instance, in Japan, the MOX reprocessing plant is as far north as possible on the main island, in Rokkasho village of the Aomori prefecture. Okinawa used to not be Japanese, it is a source of constant trouble for the Japanese government between the US army bases and Chinese spying missions and challenges, it is relatively sparsely populated, its participation in GNP is modest and most of all, it is as far as one can get from Tokyo. All these reasons should make it very tempting for politicians to choose it as a perfect nuclear waste deposit site. So if you flee from a contaminated land, there is a high chance that you’d be settling in a future contaminated one. However if you read issue no. 1 above, you know that you will mostly likely be too poor by that time to evacuate back home.

As a matter of fact, the government just settled for an operation planning with waste deposits (undisclosed sites) starting this January, as can be read in the Yomiuri Shimbun article below. More interestingly, the Japanese article from Ryukyu Shimpo hereafter simply confirm our hypothesis of a deposit in Okinawan most beautiful islands. It just makes sense that, as nuclear power plants are the main income source in rural Japan, that nuclear power waste sites will be sought after by the same.

We leave out of the discussion possible threats of a Chinese invasion / bombing in Okinawa and other unhealthy issues such as agent orange spread around and buried by the American army, as well as their unofficial, hidden nuclear weapons and hazardous materials in their bases, nor will we delve into rapes and fights by their personnel. Anyway, the main island of Okinawa where these issues exist, is an uninteresting concrete sprawl, so we are only considering the true smaller gems of the archipelago in this post.

As a conclusion, relocating in Okinawa is a medium-term viable strategy at best and candidates should be able to rely on their Embassy and wealthy relatives to organize and fund a repatriation when the archipelago will not be nuclear-free anymore and their own financial resources will have dried up in the settling process.

The Yomiuri Shimbun article is reproduced below :

Apart from the ludicrously inefficient  “usual practice to remove soil up to a depth of five centimeters”, the main highlight is the following (bold characters by SurvivalJapan), as decontamination means here waste spread kick-off date:

“The Environment Ministry will draw up plans based on a law concerning special measures on dealing with environmental contamination by radioactive substances as early as the end of November and start full-scale decontamination in January.”

28 million cubic meters of ‘hot’ soil in Fukushima / Ministry aims to set storage site guidelines

The Yomiuri Shimbun

Up to 28 million cubic meters of soil contaminated by radioactive substances may have to be removed in Fukushima Prefecture, according to the Environment Ministry.

In a simulation, the ministry worked out nine patterns according to the rates of exposure to and decontamination of radioactive materials in soil, mainly in forests.

The ministry found if all the areas which were exposed to 5 millisieverts or more per year were to be decontaminated, 27.97 million cubic meters of contaminated soil would have to be removed. The calculation covered 13 percent of the prefecture’s area.

These figures indicate the size of the temporary facilities that will be needed to store the soil, and the capacity of intermediate storage facilities where the soil will be taken later.

The assumptions were made using three categories according to yearly radiation doses in soil–20 millisieverts or more; 5 millisieverts or more; and 5 millisieverts or more plus some areas with contamination of from 1 to 5 millisieverts.

The three categories were divided further according to possible decontamination rates in forests–100 percent, 50 percent and 10 percent. The resulting nine patterns were broken down further to include “houses and gardens,” “schools and child care centers” and “farmland.”

The ministry calculated that the largest amount of contaminated soil was 28.08 million cubic meters in the case of 100 percent decontamination in forests in the category of 5 millisieverts or more plus some areas with contamination of from 1 to 5 millisieverts.

The smallest amount was 5.08 million cubic meters if 10 percent decontamination is carried out in forests with radiation doses of 20 millisieverts or more.

In the breakdown of areas with yearly radiation doses of 5 millisieverts or more, it was found 1.02 million cubic meters of soil should be removed from houses and gardens, 560,000 cubic meters from schools and child care centers and 17.42 million cubic meters from farmland.

The total amount of contaminated soil with a yearly radiation dose of 5 millisieverts or more is 27.97 million cubic meters in the case of 100 percent decontamination in forests that cover an area of 1,777 square kilometers.

The figures will be submitted Tuesday to a ministry study group that decides on the nation’s decontamination policy.

The ministry made its calculation based on an aerial survey by the Education, Culture, Sports, Science and Technology Ministry and a land use survey by the Land, Infrastructure, Transport and Tourism Ministry.

A senior Environment Ministry official said, “The standard we basically agreed on at a study meeting is decontamination in areas with yearly radiation doses of 5 millisieverts or more.”

Even though forests occupy about 70 percent of contaminated areas in the prefecture, the ministry does not believe it will be necessary to remove all contaminated soil, as long as the government restricts the entry of residents in mountainous areas and recovers cut branches and fallen leaves, according to the official.

The usual practice is to remove soil up to a depth of five centimeters. However, a senior official said this depends on the location of the contaminated soil.

The Environment Ministry will draw up plans based on a law concerning special measures on dealing with environmental contamination by radioactive substances as early as the end of November and start full-scale decontamination in January.

But the government still has not procured sufficient storage sites for contaminated soil, which has been temporarily buried in school yards or piled on vacant lots.

According to the central government, contaminated soil should be collected at temporary storage sites by local governments. The government recommends placing impermeable sheets under the soil at locations far from living areas.

The government also has no prospect of setting up intermediate storage facilities. Shortly before he stepped down, former Prime Minister Naoto Kan called on the Fukushima Gov. Yuhei Sato to set up facilities in the prefecture. The request was rejected.

Contaminated soil must be removed as soon as possible to allow evacuees to return to their houses within no-entry and evacuation zones.

Here are the maps of radiation measured by citizens at asphalt level in the nuclear-free Japanese territory. (more…)

Meteocentrale website forecast shows that radiation fall-out will reach Japan western region on Wednesday afternoon (on Honshu island : cities of Osaka, Kyoto, etc. down to Hiroshima and Yamaguchi – as well as Shikoku island) as can be seen on the screenshot below. This is the first time since the creation of SurvivalJapan that we report air-borne radiation in western Honshu and Shikoku. Since this blog is fairly new, it can be assumed that radiation fall-out over this area happened in the past and it is consistent with citizen groups radiation monitoring, which detect levels low yet superior to normal background natural radiation (Cf. CRMS Civil Radioactivity Monitoring Stations in Kansai Area Today in SurvivalJapan). (more…)
