South Koreans still distrustful of Japanese fish products after nuclear meltdown

AEN20180126000900320_01_i.jpg
SEOUL, Jan. 26 (Yonhap) — A majority of South Koreans favor banning the import of Japanese fishery products, a survey showed Friday, underscoring lingering safety concerns about possible radioactive contamination.
Radioactive water leaked following the meltdown at Japan’s Fukushima nuclear power plant in 2011.
The Consumers Union of Korea polled 1,023 adults across the country last year, and the results showed 55.3 percent want stronger import restrictions. Another 37.2 percent said the restrictions should be “very heavy.”
 
   The results of the survey were released by opposition lawmaker Choi Do-ja, who obtained them from the Ministry of Food and Drug Safety.
South Korea prohibited imports of agricultural and fish products from Fukushima and its adjacent areas after radioactive leaks following the 2011 tsunami disaster in Japan.
In 2013, Seoul took a stronger measure to ban imports from fisheries in eight other Japanese prefectures near Fukushima.
Japan took the case to the World Trade Organization, accusing South Korea of discriminating against its exports. The ruling is scheduled in the first half of this year.
According to the survey, 45.5 percent want a complete import ban on all Japanese foods, while 39.6 percent said they want at least a full ban on select products from certain prefectures.
Results showed that 55.3 percent of South Koreans are not buying fish products from Japan. Other shunned items included agricultural products (56.3 percent), dairy products (52.8 percent), cosmetics and processed foods (37.5 percent) and other manufactured goods (35.3 percent).
Among people who said they either do not buy Japanese fishery products or have cut back on such purchases, 79.2 percent said the reason was because they do not feel safe. In addition, 59.2 percent said they will not buy fish from Japan even when there is no trace of radioactive contamination.
The biggest concerns from radioactive exposure included cancer (42.4 percent), newborns with deformities (30.4 percent) and hereditary disease (13.4 percent).
“It has been seven years since the Fukushima accident, but people are still worried about fishery products from Japan,” Rep. Choi said. “There has to be more effort to allay these concerns through imports limits and thorough inspection of radioactive traces in foods.”

Population Oscillations OR Collapsing Ecosystem

From Majia’s Blog :
hjklùù.jpg
The ongoing collapse of King Salmon in Alaska is once again in the news:
Nathaniel Herz (2017, Dec 29). Southeast Alaska’s king salmon are disappearing, and fishermen are grappling with the consequences. Anchorage Daily News. Available https://www.adn.com/business-economy/2017/12/28/southeast-alaskas-king-salmon-are-disappearing-and-fishermen-are-grappling-with-the-consequences/
…There’s some sense that climate change could be causing a “regime shift” and a long-term change in ecosystems, said Peter Hagen, deputy director of a federal fisheries laboratory in Auke Bay, near Juneau.
 
“There’s a whole question: Is this a new normal? And I don’t think we’ve determined that yet,” Hagen said.
 
But Hagen and Adkison, the fisheries professor, both pointed out that salmon have proven to be resilient. Fossil records show that big population changes are typical, Adkison said.
 
“In the salmon business, we’re used to these dramatic fluctuations in productivity,” he said. “If I had to bet, I would favor the short-term fluctuation and I would expect them to eventually rebound. But the current numbers are really low.”
I’ve been following the (reported) acceleration of excess mortality events among animal populations. Here is my 2012 post on the King Salmon that “went missing” that year:
In 2013 I created a compilation of news headlines and links addressing what I called “anomal anomalies,” as documented here in this 2013 post:
 
Polar bears, walruses, salmon, sardines, starfish, etc. These and so many other marine and land animal populations experienced precipitous declines due to “inexplicable” wasting syndromes and odd infections that began being reported in great number in 2012.
 
[when I checked on bee and bat declines I discovered that the Wikipedia article attributes the rapid decline in bats from white fungal disease to 2012 here. In contrast, bee “colony collapse disorder” was named in 2006]
 
Every animal population imperiled has no doubt suffered in complex ways from human engineering and thoughtlessness, including experiences of habitat loss and rapid deterioration of remaining habitats due to the synergistic effects of countless environmental assaults.
 
Still, I find it more than coincidental that the acceleration of mass mortality events became markedly evident in 2012.
 
Fukushima’s ongoing and UNPRECEDENTED RADIOACTIVE CONTAMINATION of the ocean and the general dispersal of industrial pollutants by the Japan’s terrible 2011 tsunami ARE STRANGELY ABSENT from most all news coverage of marine welfare.
 
Yet, ALL THE SCIENTIFIC DATA available, including data generated by the US Geological Survey and the CTBTO, documented widespread fallout contamination in North America.
 
Scientific models on ocean dispersion predicted a plume of radioactive contamination would reach North America and add to the coastal fallout from precipitation by 2013. This prediction was tested and found to be true in San Diego, CA.
 
Fukushima’s ongoing dissemination of radioactive contamination has lessened since 2012 but it has not ceased.
 
I’m sure that Fukushima isn’t the only source of radioactive contamination from artificially engineered radio-isotopes such as Cesium-137 and Strontium-89 but it is the largest known.
 
Might it represent a tipping point in ocean life? That question will probably never be answerable empirically because not enough research is investigating impacts.
 
What is clear however is that the accelerated decimation of animal life on earth will not occur without grave human losses as well. It is my belief that when we destroy the eco-system upon which we depend, we are destroying ourselves.
 
Unfortunately, our capacity to grapple with the spectre of our destruction is impeded by our capacity to rationalize.
 
The idea of “population oscillations” is the rationalization deployed most often to account for the dislocations in ecological life observed by scientists and everyday people in touch with their environments.
 
Populations don’t simply oscillate by chance. Numbers drop and decline in relation to the contingencies of system-environment interactions. Precipitous declines typically result from amplifying feedback loops, often resulting from either over-population or some dramatic change in the environment, such as a sudden and unprecedented onslaught of marine contamination.

Fears of children who have to check radiation levels outside before they can go and play

The main problem is internal radiation thru food and drinking, which in this article is not enough emphasized. Plus there is no safe level of manmade radiation.

Almost seven years after the Fukushima disaster, staff are forced to check if schoolyards are too poisonous to play
1.jpg
Pupils have to scan their school playground
Children are still using Geiger counters to test for deadly radiation levels at schools struck by the Fukushima disaster in Japan.
Almost seven years after the worst nuclear meltdown in decades, staff are forced to check if schoolyards are too poisonous to play.
A large Geiger counter in their playground measures the invisible threat still hanging over them after the nearby nuclear plant was hit by an earthquake and engulfed by the ensuing tsunami.
If radiation readings are too high, the children are told they cannot go outside.
Students even have their own handheld devices to check for themselves if schoolyards are too poisonous to play in.
One, 13-year-old Yume, admits what many others also feel. “I’m afraid I’m going to get cancer,” she says bluntly.
Her classmate Mei adds: “Some of the playgrounds near here have been shut – the radiation is too high.”

Device shows readings equal to having a chest x-ray

Explosion at the Fukushima No. 1 nuclear power station on March 14, 2011
The disaster in March 2011 was the worst nuclear incident in 30 years. Now students spend lessons scanning their school and plotting hotspots on a map back in class.
Ryu, 13, explained: “The trees are where the highest readings are. We picked up 0.23 last month.”
That level is double the 0.1 millisieverts patients face during a chest X-ray, or equal to 50 scans at the dentist.
While those last just seconds, these children are exposed constantly. The Japanese government has declared Fukushima safe, with a 20-mile no-go zone around the crippled power station itself.
Science teacher Takahira Abe, 52, leads workshops designed by Save the Children to educate about the dangers.
He said: “Fukushima will be a shadow these children live with for the rest of their lives. Most were so young life seems normal, but often when we teach them about radiation they get flashbacks.”

Kids in the area are more likely to get cancer

Science teacher Takahira Abe
They are taught about monitoring radiation in local crops and fish.
Mr Abe explains: “I want them to understand the risks – and that they are more likely to get cancers. It gives them tools to protect against further dangers.”
After the disaster Mr Abe and his wife Hiromi decided not to flee – despite protests from their son and daughter, then nine and 13. He said: “The school had a geiger counter for science, so I took readings. Levels were not too high.
“My duties as a teacher were more important. I had to stay and educate others.”
His textbook was created by Save the Children to help those living under a radiation threat. And counsellors have been brought in to help deal with mental health issues.
Mr Abe adds: “That’s one positive – we’re encouraging children to talk openly. That’s not happened before in Japan.”

 

The Japanese Government Is Lying to the International Community: the Radiological Situation in and around Fukushima is NOT Safe

A report from NIRS (Nuclear Information and Resource Service, in USA)
The Japanese government has created foreign language websites which provide the information about radiology in general and the radiological situation in Fukushima. Journalists around the world, our friends and acquaintances living abroad are continually asking us whether the information that these Japanese central and local government websites present to the international community is correct or not. The following is our answer.
 
Appeal from a Japanese Anti-nuclear Activist Etsuji Watanabe
Nov.29 2017 Revised (Oct.12 2017)
Etsuji Watanabe: Member of the Japanese anti-radiation citizen-scientist group ACSIR (Association for Citizens and Scientists Concerned about Internal Radiation Exposures)
Special thanks to Mrs Yuko Kato, Mr Ruiwen Song, Ms Nozomi Ishizu, Mrs Kurly Burch, Ms Jennifer Alpern, and Mark Bennett Yuko Kato: Evacuee from Fukushima, member of the Kansai plaintiff group for compensation against TEPCO and government Ruiwen Song: Taiwanese freelance journalist.
The Japanese government has created foreign language websites which provide the information about radiology in general and the radiological situation in Fukushima. Journalists around the world, our friends and acquaintances living abroad are continually asking us whether the information that these Japanese central and local government websites present to the international community is correct or not. The following is our answer.
 pic-1.png
[Question 1]
The stories uploaded on these websites give people the impression that worrying about radiation is unnecessary. As for this impression, has Fukushima now really become a safe place to live or visit?
[Answer]
First of all, Japanese anti-nuclear activists and evacuees from contaminated areas in Fukushima and Kanto, have been warning people all over the world NEVER to trust what the Japanese government is saying about both radiology in general and the specific radiological health effects caused by the Fukushima Dai-ichi nuclear power plant disaster (hereafter Fukushima accident) following the Great East Japan Earthquake and Tsunami on March 11th, 2011.
Prime-minister Shinzo Abe and the Japanese government as a whole including Fukushima prefectural government have repeatedly declared that “with regard to health-related problems (of the Fukushima accident), I (Abe) will state in the most emphatic and unequivocal terms that there have been no problems until now, nor are there any at present, nor will there be in the future.” (Abe’s statement at a news conference). See the Japanese government website here.
This claim is completely fabricated and false. In making these claims, the Japanese government is blatantly ignoring the vast number of studies in radiological sciences and epidemiology that have been accumulating historically. By engaging in this behavior, the Japanese government has been systematically deceiving the public, both nationally and internationally.
Just think of the amount of radioactivity released during the Fukushima accident. As you know, one of the standards used to assess the extent of radioactive releases and longtime human health effects is the levels of cesium 137 (Cs137) released into the environment. Based on the Japanese government data (which is an underestimate), the Fukushima accident released 168 times the Cs137 discharged by the atomic bomb dropped on Hiroshima. This amount is almost the equivalent to the total atmospheric nuclear explosions conducted by the United States on the Nevada test ground. The Nevada desert is not designated as a residential area, but the Japanese government has recommended evacuated residents return to live in areas with radiation levels of up to 20 mSv/year. By removing economic support for evacuees, the Japanese government has forced many people who had evacuated from these areas to return.
We estimate that in the Fukushima accident approximately 400-600 times the Cs137 were released into the atmosphere by the atomic bomb blast in Hiroshima. Roughly 20% of the Cs137, or 80-120 Hiroshima-equivalents, were deposited on Japan. Of this, the decontamination efforts have only been able to retrieve five Hiroshima-equivalents. The waste from decontamination efforts is typically stored all over Fukushima mostly in mountainous heaps of large plastic bags. This means that 75-115 Hiroshima-equivalents of Cs137 still remain in Fukushima, surrounding prefectures, and all over Japan.
In addition, the Japanese government is now planning to reuse the retrieved contaminated soil under 8000Bq/kg in public works projects all over Japan. This self-destructive program has now been partially started without any announcements as to where the contaminated soil are and will be reused, under the pretext of “avoiding damage caused by harmful rumors”. This project is tantamount to scattering lethal fallout of Cs137 equivalent to about 5 times that of Hiroshima bomb all over Japan. The Japanese government is literally behaving like a nuclear terrorist.
Do you really imagine that Fukushima prefecture and surrounding areas, contaminated as they are to levels similar to the Nevada test site, is really a safe place for people to permanently live, or for foreign tourists to visit and go sightseeing?
Regrettably, we must conclude that it is not, for either residents or tourists the situation in Fukushima is not safe.
 pic-2.png
[Question 2]
These websites also point out that the international annual dose limit for the public is at 1mSv, but this level is easily exceeded by only one CT-scan, insinuating that this 1mSv standard is set too low and thus not a useful indicator.
[Answer]
CT-Scans are often cited as if they had no radiation risks, But this is not true. A recent study clearly shows that every CT-scan (about 4.5mSv irradiation) increases the risk of cancers in children by 24%. See the website here.
In Fukushima the allowable level of radiation per year for residents is now 20mSv. Can you imagine having 4-5 CT-scans every year?
 pic-3.png
[Question 3]
One of the websites states: “In Fukushima, the indoor radiation doses are now so reduced that no radioactive cesium can be found in the air. Therefore, no radioactive particles can invade the human body during breathing.” What do you think of this statement?
[Answer]
The Japanese government also ignores the long-term peril caused by “hot particles” ――micron-and- nano-sized radioactive particulates――which, if inhaled or absorbed into the human body, may lead to many kinds of cancers and other diseases including cardiac failure. We should consider internal irradiation to the cells near the radiation sources to be 500 times more dangerous than external irradiation because particles inside the body radiates very near or even inside cells, causing intensive damage to DNAs and other cell organs such as mitochondria.
 
[Question 4]
These websites explain that there exists not only artificial but also natural radioactivity, thus people are living in an environment surrounded by radiation all the time in everyday life.
[Answer]
One of the main tactics that the Japanese government often uses to propagate the “safety of low level irradiation” is to compare artificial radioactivity with natural radioactivity. But this logic is a methodological sleight of hand. It is crystal-clear that even exposure to natural radioactivity has its own health risks. Cancers sickened and killed people long before artificial radioactivity was used. For example, Seishu Hanaoka, one of the founders of Japan’s medicine, carried out 152 breast cancer surgeries from 1804 to 1836.
Both kinds of radioactivity have their own health risks. Risks caused by artificial radioactivity should not be compared but be added to the natural radioactivity risks as they both lead to the accumulation of exposure.
For example, potassium 40 (K40) is a typical natural radioactive nuclide. According to  the Japanese government, the average internal exposure dose for adults from K40 is about 4,000Bq/year or 0.17mSv/year. See the website here (in Japanese).
The ICRP risk model (2007) allows us to estimate the approximate risk posed by K40. The calculation shows that K40 is responsible for approximately 4,000 cancer cases and 1,000 deaths every year. If the same amount of radiation was added to that of K40 in the human body by artificial sources, the cancers and mortalities would be doubled to 8,000 and 2,000 a year, respectively. Based on the ECRR (2010) model, which criticizes the ICRP risk model as a severe underestimate, these figures should be multiplied by 40, reaching 320,000 and 80,000, respectively.
The extract you cite from the Fukushima government website is completely fake: “In Fukushima, the indoor radiation doses are now so reduced that no radioactive cesium can be found in the air. Therefore, no radioactive particles can invade the human body during respiration”. Reports from civic radiation measurement stations refute this claim. For example, dust collecting paper packs of vacuum cleaners used in Iwaki City, Fukushima prefecture, are radiologically measured and 4,800-53,900Bq/kg radioactive cesium was detected in Oct-Dec 2015. See the website here (in Japanese).
 
[Question 5]
One of the websites says that the Fukushima prefecture has conducted whole-body counter screenings of the 170,000 local population so far but cesium was rarely detected.” Does this mean that we can safely consume food from Fukushima, and Fukushima residents are no longer being exposed internally to radiation?
[Answer]
This is a typical example of demagogy by the Japanese government: vague expressions lacking specific data, using the words “safe and secure” without clear explanation. In reality, the government has not publicized any data indicating serious irradiation of the population. For example, you mentioned the Fukushima prefectural government website saying that whole-body counter screenings of 170,000 members of the local population have found radioactive Cs only in very few cases. However, the fact that no specific number is given makes the statement suspicious.
These statistics, more than likely, exclude many firefighters or other municipal employees who, at the time of accident, helped local residents evacuate from a lot of contaminated areas surrounding the defunct Fukushima plant. These people were subjected to serious radiation doses.
Civic groups’ efforts for the disclosure of information has recently prompted city officials near the defunct plant to disclose the fact that it conducted whole-body counter check-ups on about 180 firefighters, nurses and municipal employees. According to Koichi Ohyama, a member of the municipal assembly of Minami Soma, the screening conducted in July, 2011, showed almost all of these people tested positive in Cs. The maximum Cs137 dose among the firefighters was as high as 140,000 Bq. This data reveals a part of the reality of irradiation but it is only a tiny part.
 pic-4.png
[Question 6]
The government websites suggest that no health effects from irradiation have been reported in Fukushima. Is this true? Or have any symptoms appeared that indicate an increase in radiation-induced diseases in Fukushima?
[Answer]
One example is the outbreak of child thyroid cancer, but the Japanese government has been denying the relationship with irradiation from radioactive iodine released from the Fukushima disaster.
Japan’s population statistics reflect the health effects from the Fukushima disaster radioactivity. The following data clearly show that diseases increasing in Fukushima are highly likely to have been radiation-induced.
pic-5-768x597.png
[Question 7]
The Fukushima prefecture website says, “After the Fukushima accident, the Japanese government has introduced the provisional standards for radioactive iodine and cesium. The Fukushima prefectural government subsequently strictly regulated distribution and consumption of food with levels of radioactivity exceeding the provisional standards. Now we have had this new much stricter standard. The distribution and consumption  of food exceeding this new standard has been continuously regulated; therefore any food on the market is safe to consume.” Is it true?
[Answer]
As for food contamination, the Japanese government has also tried to cover up the real picture. First, the current government standard for radioactivity in food, 100Bq/kg, is dangerously high for human health, especially for fetuses, infants, children and pregnant women. Even six and a half years after the accident, the Agriculture Ministry of Japan as well as many civic radioactivity measurement stations all over the country have reported many food contamination cases, although the frequency is evidently reduced. See the website here.
The Japanese government has underestimated the danger presented by internal irradiation. But, we must consider two important factors. (1) The wide range of difference in personal radio-sensitivity. According to Professor Tadashi Hongyo (Osaka University Medical Faculty), the maximum difference is as wide as 100 times in terms of biological half-life of Cs137. (2) Recent studies denying that the so-called biological half-life decrease curve actually exists. According to the new model, daily food contamination can cause concentrations to accumulate as time passes. Even a daily 1Bq internal radiation dose from food cannot be safe for human health (details below).
Our recommendation is to be cautious of food or produce from Fukushima and the surrounding areas, and, even if contamination levels are said to have now generally decreased, to avoid jumping to the conclusion that all the food is fit to eat.
 pic-6
[Question 8]
We would like to ask about the situations in prefectures surrounding Fukushima. A television program once reported, “As for the safety of Tochigi and Gunma prefectures, few people are raising concern about health effects of radiation.” Is it true that the prefectures somewhat distant from the Fukushima Daiichi plant are now safe with no human risk?
[Answer]
Regarding the radioactive contamination in prefectures surrounding Fukushima, you can refer to the following website.
This article examines the contamination in the Tokyo metropolitan area, but conditions are the same or more serious in Tochigi or other prefectures north of Tokyo, nearer to the defunct Fukushima Daiichi plant.
Another example is the statistics of stillbirth and neonatal mortality in Fukushima and the surrounding five prefectures (Tochigi, Gunma, Ibaragi, Miyagi, Iwate) shown here.
Perinatal mortality in not only Fukushima prefecture but also neighboring prefectures rose 15.6% just 10 months after the accidents. This clearly indicates the existence of some kind of human health damage from radiation.
pic-7.png
[Question 9]
We would like to ask about the decontamination efforts by famers living in Fukushima and neighboring prefectures. Should we think highly of the farmers measuring the amount of radiation deposited on the surface of soil to create radiation maps for farms, or washing the radiation from the surface of every single tree off the radiation with high-pressure washers? The farmers said that while these methods have been shown to be radiologically effective, their produce did not sell well, because consumers are still feeling anxious about health risks. Does the problem of radioactive food contamination in Japan just end up in whether each consumer personally believes it safe or not?
[Answer]
We must raise a question that, despite the government’s decontamination efforts, a huge amount of radioactive materials deposited in mountainous areas remain untouched. Now they are re-dispersing and re-depositing over wide areas of Fukushima and surrounding prefectures via winds, cars, trains, river water, pollen, spores, emissions from incinerators, in the form of radioactive dusts and particulates, among many others. For an example, see the following website.
So I regret to say that, although these farmers’ endeavors you mentioned are very precious and respectable, they are not sufficient to completely eliminate the risk of radiation exposure from food. The problem exists objectively in the nuclear materials deposited on and in soil, algae, plants, houses, buildings, forests, animal and human bodies, not subjectively in the consumers’ sentiment or psychology.
 pic-8-768x463.png
[Question 10]
Japanese experts have recently pitched a cultivation method that can remove cesium by intensive use of potassium fertilizer. Is this method effective at all? Do you have any doubt about their claims?
[Answer]
They seem to be among those experts who have been criticizing the general public’s tendency to demand “zero irradiation risk” as an obstacle to Fukushima reconstruction.
As you know, cesium (Cs) has chemically similar characteristics to potassium (K). So it is true that higher levels of application of potassium fertilizer lowers the plant’s absorption, and therefore concentration, of radioactive Cs, decreasing Cs137/134 concentrations in produce, often to below the government standard of 100Bq/kg. But the following problems remain: (1) This procedure can prevent Cs transfer from the soil to produce only partly, not completely; (2) This process raises the potassium concentration in the produce and therefore heightens the burdens on certain human organs such as kidneys, the heart and the nervous system, causing new health risks; (3) Heightened concentration of potassium also leads to the heightened concentration of radioactive K40, so the reduced risk of radioactive Cs lead to an increased risk of internal irradiation by K40.
 
[Question 11]
Even if cesium concentration was reduced by applying more potassium fertilizer than usual, strontium contamination would remain. In Japanese government’s international press campaign as to the Fukushima accident, almost nothing has been said about strontium. If you have any information on strontium contamination, let us know.
[Answer]
We regret that the information about strontium that you are asking for is very limited and searching for it is also a challenge for us. The Japanese government and research institutes under the government have reported very limited data regarding strontium contamination. But it is important that the Japanese government admits the fact of strontium contamination within 80km from the defunct Fukushima plant. See the website here.
Did you know that the US Department of Energy data on the strontium contamination of soil in Japan and its visualization (in Japanese)  can be seen on the websites here?
 
[Question 12]
Some Japanese experts say, “the Japanese government has declared that no health effects from irradiation below 100mSv (or 100mSv/year) have been confirmed.” Some farmers have established a private food standard of 20Bq/kg, much lower than the Japanese government standard of 100Bq/kg. Do you think that doses under 100mSv or under 20Bq/kg are safe and secure?
[Answer]
As you mentioned, the Japanese government claims that no scientific studies verify that irradiation of 100mSv or less poses a threat to human health, suggesting that irradiation under 100mSv has no risk. This, however, is false. The government is fabricating this information. In fact, very many scientific studies have already confirmed and proven health effects induced by irradiation under 100mSv. For example, see the websites below.
 
The Japanese government is using the term “100mSv” in a deliberately ambiguous and confusing manner. The expression 100mSv can have three meanings: (1) a one-time irradiation dose, (2) cumulative irradiation doses, or (3) annual irradiation doses. So 100mSv is not the same as, nor equal to the 100mSv/year that you mentioned in parenthesis. The latter amounts to a 1Sv in cumulative dose over 10 years (which is an up to 10% lethal dose), and 5Sv over 50 years (which is a 50% lethal dose). The present government standard for evacuees to return, 20mSv/year, means that living there for 5 years leads to a cumulative dose of 100mSv, at which the Japanese government admits clear health risks.
Regarding 20Bq/kg as some farmers’ private food standard, it is critical to pay serious attention to the extraction process of Cs from tissues. Japanese-Canadian non-organic biochemist Eiichiro Ochiai points out in his book “Hiroshima to Fukushima, Biohazards of Radiation” (2014) that, based on the Leggett model, the Cs concentration injected in tissues at one time diminishes relatively quickly for about 10 days in most tissues. After that, processes slow down, tending to become steady. He writes: the decrease of the overall Cs level in the body does not follow an exponential decay curve (p.83). This means that consecutive intake of Cs, even in very low levels, results in the accumulation of Cs in the body. (Incidentally, Ochiai’s book can be downloaded for free from the website below.)
Regarding the Leggett model, see the website below.
Yuri Bandazhevsky considers over 10Bq/kg of radioactive Cs concentrations in the body to be unsafe because even this low level can possibly cause abnormal electrocardiographic pattern in babies, metabolic disorders, high blood pressure, cataracts, and so on.
Therefore, we can conclude unequivocally that neither the irradiation under 100mSv nor the privately set 20Bq/kg food standard are safe and secure.

1,700 Contaminated Vehicles Removed from Fukushima Daiichi Plant Site

 

Excessive radiation detected in vehicles removed from Fukushima nuke plant

Some of the cars were sold on the used-car market while two others remain unaccounted for, according to plant operator Tokyo Electric Power Co.

Radiation topping the government-set limit has been detected in about 190 vehicles removed from the premises of the Fukushima No. 1 Nuclear Power Plant after the outbreak of the nuclear crisis, it has been learned.

Some of the cars were sold on the used-car market while two others remain unaccounted for, according to plant operator Tokyo Electric Power Co. (TEPCO).

Approximately 1,700 vehicles were parked on the premises of the power station when the nuclear crisis broke out after it was hit by the powerful earthquake and tsunami on March 11, 2011, TEPCO officials said. Of those, about 600 were owned by employees of TEPCO or companies contracted by the utility. Over a 12-day period until radiation screenings began on March 23 of that year, people could drive the vehicles out of the premises of the plant without checks.

The Economy, Trade and Industry Ministry instructed TEPCO in February 2012 to conduct a follow-up probe into the use of these vehicles for fear that next owners of those cars could be exposed to radiation without knowing that the vehicles were contaminated.

The power company conducted a survey on employees and contracted companies that parked their cars on the plant’s premises at the time of the accident, and confirmed that about 460 vehicles were brought out of the plant by April 2015. It was learned that radiation levels for around 190 of the vehicles exceeded government-set safety standards, and some of them were found contaminated with radiation nearly 10 times over the limit. All the vehicles whose radiation levels exceeded the limit were collected from their owners and are now stored on TEPCO’s premises situated in a Fukushima Prefecture area designated as a highly contaminated “difficult-to-return zone.”

TEPCO is considering how to dispose of these heavily contaminated vehicles, with an official saying, “We’d like to continue searching for two vehicles that remain unaccounted for and respond to the situation in an appropriate manner.”

Tainted cars left Fukushima compound unchecked

The operator of the Fukushima Daiichi nuclear power plant says hundreds of vehicles contaminated with radioactive substances left the compound unchecked in the immediate aftermath of the 2011 accident.
Tokyo Electric Power Company says that in 2012 it began investigating what had happened to privately owned vehicles at the plant, and found that about 460 had left the compound.
TEPCO officials located most of them by 2015. About 190 registered radiation levels that were higher than the government standards. They managed to track down all 190, but some of them had been sold to new owners.
Some of the cars were so contaminated that the radiation couldn’t be measured by equipment capable of detecting levels nearly 10 times greater than the official limits.
Two vehicles remain unaccounted for.
TEPCO says it did not conduct radiation checks of cars leaving the compound for 12 days after the accident started on March 11th, 2011.
The company has apologized for causing concern and says it will keep trying to locate the 2 vehicles.

Olympic games in Fukushima: Is it safe?

1.jpg

 

Fukushima city is going to host Olympic baseball and softball games in 2020.
What is the level of radio-contamination there? This is the question on everybody’s mind, spectators and players from all over the world. Is it really safe?

Baseball and softball games will take place in Azuma Sports Park in Fukushima city.

Fukushima prefecture provides the information below on the radiation measurements of the Park.

Measurements of the airborne radiation dose in the baseball stadium: No 13-16
Those of the softball stadium: No 4
The lines above and below indicate the value of the radiation dose at 1cm and 5cm above the ground.

We notice that, as usual, Fukushima prefecture gives only measurements in terms of radiation dose. Based on this information, one might think that it would be relatively safe to play there or to attend the games. However, monitoring only the radiation dose is not enough for radioprotection. The radiation dose is an indication of external irradiation exposure. In this case, the measures of radioprotection will be to stay away from the radioactive objects or not to stay in their vicinity for a long time. But the radiation dose does not provide information to avoid the risk of internal irradiation. For this latter, it is necessary to monitor surface contamination density or concentration, in this case, of soil (in terms of Becquerels/m2 or Bq/kg), as well as the concentration of radioactive substances in the air (Bq/m3). The radioprotection measures against internal irradiation would be wearing protective gear and masks to avoid the radioactive substances from adhering to the skin and/or entering the body.

 

Here is some information provided by Yoichi OZAWA of « Fukuichi Area Environmental Radiation Monitoring Project », the group of which we have published several soil contamination maps in this blog. OZAWA took measurements on July 27 at the request of the ARD German TV channel team which was visiting Fukushima.

Contamination concentration and density of 5cm surface soil around the Azuma Baseball Stadium

Point A : The entrance of the « Torimu no Mori» where children play.
Radiation dose at 1m above the ground : 0.12 μSv/h
Radiation dose on the ground : 0.19µSv/h
Surface concentration : 605 Bq/kg
Surface density : 47,300 Bq/m2

Point B : In front of the Multi-purpose Fields.
Radiation dose at 1m above the ground : 0.10 μSv/h
Radiation dose on the ground : 0.22µSv/h
Surface concentration : 410 Bq/kg
Surface density : 31,200 Bq/m2

To interpret these figures, let us remind you that in Japan, according to the Ordinance on Prevention of Ionizing Radiation Hazards, places where the effective dose is likely to surpass 1.3mSv in 3 months (approximately 0.6µSv/h of airborne radioactivity) or the contamination density to exceed 40,000Bq/m2 are designated as a « Radiation Control Zone » and public entry must be severely restricted. People under 18 years old are not allowed to enter, and even adults, including nuclear workers, cannot stay more than 10 hours. It is prohibited to eat, drink or stay overnight. To leave the zone, one has go through a strict screening to check for radioactive substances leaving the zone, a measure to protect the individual person as well as the environment.

We do not have the measures of surface density of the baseball nor softball stadiums, but in answering the question of the above German TV team, the information was given as to the decontamination work and radiation dose. There had been decontamination work, and the airborne radiation dose was about 0.04µSv/h in the baseball stadium.

Even when decontamination work has been carried out in the stadium, the mountains and woods behind the park have not been decontaminated, and wind and rain bring the radioactive substances towards the park. Besides, as we can see above, other places in the park are highly contaminated when we look at the surface contamination. They represent high risks of internal irradiation. Moreover, according to recent research, radioactive particles disseminated by the Fukushima Daiichi nuclear accident are mostly insoluble in water. This characteristic makes the health hazard much worse than in the case of the usual water soluble Cesium (see English transcription of NHK documentary on Insoluble Radioactive Particles in this blog). We believe that this Park should not be open to the public, especially to children.

The small type of insoluble radioactive particles – also called Cesium balls -, are dispersed in the Tokyo metropolitan area. People who visit this area should be careful and should take adequate radioprotection measures especially when it is windy and the radioactive particles can be re-disseminated.

All in all, we believe that there is far too much risk for the players and spectators to participate in the Olympic games in Fukushima. Fukushima should not host the Olympic games. Furthermore, we are against holding the Olympic games in Tokyo.
