The News That Matters about the Nuclear Industry

Many children diagnosed with thyroid cancer after 3.11 disasters, families still worried

ghhkklù.jpg
Nearly 80 percent of respondents in a survey by a group supporting children diagnosed with thyroid cancer in the wake of the Fukushima nuclear disaster say they remain worried about the cancer, despite the prognosis for those who receive appropriate treatment being good.
 
The survey was conducted by the 3.11 Fund for Children with Thyroid Cancer, an independent, not-for-profit organization providing support for child patients of thyroid cancer and their families. It was sent in August to 67 households of people who were living in Fukushima Prefecture at the time of the outbreak of the disaster at the Fukushima No. 1 Nuclear Power Plant in March 2011 and whose medical expenses the fund has helped to cover. A total of 52 households responded — a response rate of about 78 percent. Twelve of the respondents had received treatment themselves, while seven were fathers and 33 were mothers of those who had been treated.
A total of 40 respondents, or 77 percent, said they remained worried. When asked specifically what they were worried about, 23 people said “a relapse,” nine each cited “metastasis” and “health status in general,” while five each said they were worried about “pregnancy and childbirth” and “finding a job and working.”
Among children, some worried about cancer testing being scaled back. A total of 28 respondents called for the status quo to be maintained, while another 17 respondents called for the testing system to be enhanced. None said it should be downsized.
“Excessive diagnosis” has been blamed in the past for the large number of thyroid cancer patients in the wake of the nuclear disaster, but when given space to write their own opinions, some respondents were supportive of testing from the perspective of early detection of cancer, saying, “It’s better than finding out too late,” and “If a person has cancer, they’ll feel better if it’s removed.”
The fund’s representative director, Hisako Sakiyama, commented, “There’s a need to listen to what the afflicted people and their families want, and to hear what problems they are facing.”

No way to find hot spots with dosimeter at 1m from the ground

Special thanks for their very important work to Kurumi Sugita of the Fukushima 311 Voices Blog and to Mr Yoichi Ozawa of the citizen’s measurement group named the “Fukuichi Area Environmental Radiation Monitoring Project“.
We have published several articles in this blog saying that to protect the population the Japanese goverment should take into account the soil contamination as well as the radiation dose in the air.  The policy to open the evacuation zones and encourage the population to return to live there (with the end of financial compensation and relocation aid) is based only on the airborn radiation dose measurements (the evacuation order is lifted when the radiation dose is under 20mSv/year).  We have been saying that this is very dangerous, even  criminal, for the air radiation dose rate (indicating the amount of radioactive dose received by a person within a certin period time) is useful with a well-identfied fixed source of radiation, but is not adequate to reveal the overall environmental contamination after a nuclear accident. It doesn’t account for the internal radiation exposure induced health hazards (note 1).
Now we would like to point out another problem related to hotspots: it is nearly impossible to find hotspots by the usual measuring practice of the airborn radiation dose rate (in sieverts per unit of time).  To illustrate this difficulty, we are translating here a Facebook post of Mr Yoichi Ozawa of the citizen’s measurement group named the “Fukuichi Area Environmental Radiation Monitoring Project“.
 
Here are the radiation dose rates, captured vertically above a highly radioactive substance (“black substance” or “black dust”) of 4,120,000 Bq/kg, measuring 79 μ Sv/h.
Below are measurements at different distances from the ground.
5cm:9.112 μSv/h
50cm:0.630 μSv/h
1m:0.251 μSv/h
Nov 30 2017.jpg
Conclusion: it is impossible to discover micro-hotspots right under your feet when you walk around measuring radiation doses at 1m of distance from the ground.
Measuring device:
Aloka TCS172B
Measurements carried out by Mr Yoichi Ozawa.
For 0cm from the ground, Aloka TCS172B, which cannot measure over 30µSv/h, was replaced by Polimaster PM1703M and Radex RD1706. The value is the average of the measurements of these two devices.  
 
Here is the video of the measurement.
As we can see from the graph above, the value in terms of Sieverts decreases drastically with the distance from the ground. At 1m, which is the usual reference height to measure the radiation dose rate, the value becomes very small even with the soil of over 4 million Bq/kg, which is absolutely enormous (note 2).
Some readers might be familiar with the image of a Japanese citizen measuring  radioactivity with a device at about 1m from the ground. This practice, almost unknown before the Fukushima Daiichi nuclear accident, has become widespread among citizens, although it has become rather a rare practice nowadays as many people have more or less become accustomed to live with radiation. Besides the fact that it is hard to live a life worrying about radiation around the clock and some people prefer to stop thinking about it, this “normalisation” of radiation is strongly enforced by a governmental security campaign. One of the methods employed is to focus on the external irradiation risk, neglecting the internal irradiation risk, by spreading the knowledge and data only in terms of the radiation dose in the air (measured by Sieverts), at the expense of other measurements such as the radiocontamination density in soil (surface contamination density in terms of Becquerel/unit of surface).
One of the now well-known problems of radiocontamination of the environment is that the contamination is not homogeneous, but dispersed with what is called a hot spot. This is a serious problem for the population, as the absorption of radioative particles contained in these hot spots can cause internal irradiation related health damage. And as we see above, it is extremely difficult to detect these hotspots, from 1m and above, even with the extremely highly contaminated substance such as “black dust”.
It is widespread belief among the public that if the value of the airborn radiation dose at 1m from the ground is under 0.23µSv/h (note 3), it is safe. This value, diffused by the authorities as well as by media, is indeed applied as the lower limit to carry out decontamination work.  Yet, as we have seen, even with the extremely highly contaminated substance such as “black dust”, at 1m, the radiation dose is only 0.25µSv/h, that is to say, only slightly over the limit of the 0.23µSv/h, which is believed to be the “safety level”.
It is unfortunate to say that for most of the residents taking the measurements of the airborn radiation dose by themselves, the values they observe have become rather an “encouraging” factor to continue living there or to return to live, than an alarming factor, as these values do not reveal but rather conceal the presence of hotspots which can cause internal radiation exposure induced health damage.
It is difficult to find hotspots anyway.  So when the soil contamination is high (see the concentration maps in this blog, for Namie, Minamisoma), it is better to keep the zone closed, continuing to aid the evacuated people.
 
Note 1: In opposition to the external radiation exposure which occurs when the human body is exposed to an external source, the internal radiation exposure is an exposure from inside the body due to the incorporation of radioactive particles through ingestion, inhalation or adhesion to skin.
Note 2: This extremely high level of contamination is understandable, for what is measured here is the infamous “black substance” or “black dust”, a kind of Cyanobacteria, about which we invite you to listen to podocast of Marco Kaltofen with English transcription.
Note 3: In fact, the 0.23µSv/h value is problematic in itself.  This is based on the 1mSv/year value following the ICRP (International Commission on Radiological Protection) recommendations on the public health.  However,  the 0.23µSv/h value is not the result of a simple division of 1mSv by 365 days x 24 hours. The calculation of 0.23µSv/h presupposes that people stay inside for 16 hours/day and that the radiation is reduced by 60% because of the building structure.  Then, the background of 0.04µSv/h is added. (1000µSv÷365÷(8 + 〈16×0.4〉) + 0.04  But in the real life in rural areas such as Fukushima, people spend more time outdoors.  Besides, some recent research has shown that in some cases the radiation dose can be higher indoors than outdoors because of the infiltration of hot particles. Thus, the reality is much more complex to apply uniformly the value of 0.23µSv/h as a safety threshhold. Lastly, many people in Fukushima were victimes of the initial exposure right after the accident. For such population, any exposure, whatever the quantity is, is to be avoided.

Testimony of a mother who evacuated from Tokyo

Listen to her testimony (in English).
She evacuated from Tokyo to Kobe in west Japan to protect her daughter.
The contamination does not stop at the Fukushima department border. Tokyo is also contaminated.

 

 
Transcription (note 1):
I am standing here to tell you that the Fukushima nuclear catastrophe is not over.
I evacuated to Kansai (note2), three years after the Fukushima nuclear power plant accident.
Where do you think I evacuated from?
I evacuated from Tokyo!
Do you know that Tokyo has serious radioactive contamination?
Tens of millions of people in east Japan live with radioactive contamination now.
I have a daughter who was 5 years old at the time of the accident.
She became very sick one year after the accident.
In fact, my daughter became so sick that she could not live a normal life at all.
However, when she stayed in a place where there was no radioactive contamination, my daughter became so well. But when we returned to Tokyo, my daughter became sick again.
We did not have the option to stay in Tokyo, we just fled from Tokyo and came here.
Living in east Japan means living with many radioactive materials, and it is not a place where people can live healthily.
We are calling for evacuation to west Japan.
We are evacuees from eastern Japan.
Our existence will not be broadcasted on radio waves or published in newspapers. So, I am telling you about it now.
After the accident, we were told that radiation was not a problem, health damages would not occur.
But it was not true.
Many of us have evacuated from east to west due to various health problems.
Many people are getting sick today in east Japan.
People are dying without noticing that it is due to radiation.
Many Japanese can not face this nuclear catastrophe.
Please try to know what is going on in Japan now.
We are telling the world that the nuclear disaster is far from being over.

New Study: Over a Trillion becquerels of Fukushima radiocesium fell on Hawaii

serveimage
University of Hawai’i at Mānoa, Oct 31, 2017
Fukushima-derived radiocesium fallout in Hawaiian soils… This study estimated the magnitude of cesium deposition in soil, collected in 2015-2016, resulting from atmospheric fallout… Detectable, Fukushima-derived 134Cs inventories ranged from 30 to 630 Bq m-2 and 137Cs inventories ranged from 20 to 2200 Bq m-2… This research confirmed and quantified the presence of Fukushima-derived fallout in the state of Hawai’i in amounts higher than predicted by models and observed in the United States mainland…
The Hawaiian Islands were expected to get minimal, below 10 Bq m-2 or lower, of Fukushima-derived fallout…
Fukushima-derived soil radiocesium concentrations, were greater than anticipated based on model-predicted Pacific atmospheric dispersion rates…
Maximum estimated values of 134Cs fallout on the islands of Hawaii and O’ahu constrained by precipitation and data from sites with less than 70% canopy cover were obtained by linear interpolation of all measured soil cesium concentrations, resulting in 134Cs fallout ranging from < 60 to 1000 Bq m-2 [According to this study, “The Fukushima-derived fallout… 134Cs to 137Cs ratio was 1:1” — therefore 137Cs fallout from Fukushima was also 60 to 1000 Bq m-2, making the total radiocesium 120 to 2000 Bq m-2. Compare this to the study’s previous statement that “The Hawaiian Islands were expected to get minimal, below 10 Bq m-2 or lower, of Fukushima-derived fallout”]…
Using the conservative values and integrating over the whole area with rainfall above 200 mm, we estimate that the island of Hawaii received 1.50 x 10^12 Bq [1.5 Trillion Bq] of 134Cs and 137Cs, each isotope contributing 50%, between March 19 and April 4, 2011…
Atmospheric dispersion models predicted the majority of the plume to travel a more northern route over the Aleutian Islands… however, suggesting that the Fukushima-derived aerosol plume may have taken an alternative southern path. Our radiocesium fallout inventories are comparatively higher than those estimated and measured in North America. Previous research that used whole-water wet deposition to predict ‘its fallout in North America estimated up to 180 Bq m -2 in Alaska, 46 Bq m -2 in California, and 29 Bq m -2 in Washington State…
This is the first study to our knowledge studying Fukushima-derived fallout in the Pacific Islands…

Activists call on artists to join protests against 2020 Olympics in Tokyo

10325401_10204102291517461_1178696755673550066_n
The idea of the Olympics as a sporting event complemented by culture goes back to Pierre de Coubertin, the founder of the modern Games. The Olympic Charter also states that the Olympic Movement is composed of sport, culture and education. These elements were often blended, as in the prewar Games that included such events as poetry and painting. From 1912 to 1948, arts competitions were held in parallel with the sporting events, though growing discontent meant this curiously hybrid system was jettisoned in favour of separate arts and cultural festivals held alongside the sports. From Barcelona in 1992, the idea of a Cultural Olympiad took hold, whereby a series of arts and cultural events would be organized during the four-year Olympiad period to culminate with the Games, though this had already happened de facto at past Games.
Now the leading figures in the protest movement against the 2020 Tokyo Olympics have called for an anti-Cultural Olympiad. In the recently published Anti-Olympics Arts Council Statement of Purpose, activists point to the destruction of public housing and eviction of homeless people as part of the preparations for the Olympics in Tokyo. The statement ends with a call to action:
For residents of urban areas, and especially the poor, the Olympic/Paralympic Games are nothing but a huge catastrophe. We, the Anti-Olympic Arts Council, call for you to resist and protest against these mega events. We call on artists, performers, poets, and all that use the arts as their medium—oppose the Olympic Games.
It is often said that artists in Japan have avoided direct political engagement in past decades, preferring more oblique modes of socially engaged practice, though the post-Fukushima zeitgeist has certainly produced some prominent examples of overtly politicized art. The prospect of the Olympics and Cultural Olympiad in 2020, given the geopolitical situation in the region as well as such ongoing major socio-cultural questions as Fukushima, Constitutional change and Japan’s demographic time bomb, necessarily conjure up a dilemma for the arts. How will the arts respond? Will artists protest, ignore, borrow or participate?
 
The most notable and lasting case of an artistic response to the 1964 Tokyo Summer Olympics is surely Kon Ichikawa’s nearly three-hour documentary film Tokyo Olympiad (1965). Arguably, the Olympics “propaganda” film subverts the brief, focusing on many of the small moments and the ordinary people among the spectators. It starts with the rising sun and then a wrecking ball while the narration enumerates the iterations of the modern Games and their host cities. The Olympics have noble aspirations, as Ichikawa acknowledges from the opening epigraph, but the reality, at least initially, is demolition. It ultimately segues into a somewhat more predictable, yet staggeringly meticulous, hymn to the facilities created for the 1964 sporting events, the participating athletes and the competitions themselves, but the underlying social commentary is more subtle.
The 1964 Olympics were more conspicuously satirised by the art collective Hi-Red Center when its members set about cleaning the streets of Ginza in white lab coats, a stunt intended to mock the city’s attempts to spruce up its appearance ahead of the Games. Recent moves in Japan to expunge pornographic magazines from retail outlets is an indication of the “cleaning” likely to take place prior to 2020.
One of the early projects of Akira Takayama’s theater collective Port B examined both the famous 1964 Games but also Japan’s “phantom Olympics”, the 1940 Games that were canceled due to World War Two. Tokyo/Olympic (2007) was a tour several hours long around the city on a chartered Hato Bus that took in the sites of the 1964 Games, but finished rather unexpectedly at a rather desolate location in Tokyo Bay. Participants could look across the bay to see the artificial island of Yumenoshima (literally, “island of hope”), which was made from the city’s trash, and a projected venue for the abandoned 1940 Games. (See Peter Eckersall, “Memory and City: Port B and the Tokyo Olympics” in Performativity and Event in 1960s Japan: City, Body, Memory, Basingstoke: Palgrave Macmillan, 2013.) The bay area will play host to many of the venues for the 2020 Games at a time when the government, say its critics, is attempting to steer the nation back towards its prewar past.
The upcoming Olympics in Tokyo have already succeeded in coopting many artists for its pageantry. One of them is the singer Ringo Sheena, though she recently got flamed by liberals for her nationalist comments in a July interview with the Asahi Shimbun in which she declared that “the whole population is the organizing committee” for the Games. “In that sense, it’s very Japanese in its respect for harmony.” No individual opinions are anticipated.
More specifically, the direction and content of the actual 2020 Games’ cultural program is the source of much anxiety in the arts world in Japan, since so little is known. Certain commercially driven artists have been announced as part of the Cultural Olympiad, but firm details are still under wraps. So far what we have been shown has largely consisted of the “Tokyo Caravan” performances, overseen by Hideki Noda, beginning in 2015 and then continuing at Rio de Janeiro and Tokyo’s Roppongi Art Night in 2016. Ostensibly this would qualify the program as an “Olympiad”, even if the events are apparently mere previews without a genuine feeling of sequence or overall curation. Alongside the Roppongi Art Night performance, an event in autumn 2016 “fusing traditional arts and the latest technologies for which Japan is famous”, officially launched the Olympiad as an “ambitious programme of cultural activities”. The veracity of that boast remains to be seen.
It is certainly the case that various celebrities and artists will benefit financially from the Olympics and Cultural Olympic. One of the reasons that Expo ’70 in Osaka was also such an iconic event was the participation of major figures from the arts, though this was not without intense controversy at the time — so much so that an “anti-expo” was held. Now that there is an Anti-Olympics Art Council, perhaps we can expect such a counter-event, an Anti-Cultural Olympiad, in 2020.

Fukushima’s Radioactive Legacy

From Majia’s Blog

Did you see the article by Jeff McMahon in Forbes covering research by Dr. Shin-ichi Hayama, a wildlife veterinarian studying Fukushima’s contaminated monkeys:

Jeff McMahon (2017, October 30). Three Ways Radiation Has Changed The Monkeys Of Fukushima. Forbes, https://www.forbes.com/sites/jeffmcmahon/2017/10/30/three-ways-radiation-has-changed-the-monkeys-of-fukushima-a-warning-for-humans/#15b788165eac

The Japanese macaques show effects associated with radiation exposure—especially youngsters born since the March 2011 meltdowns at the Fukushima-Daiichi Nuclear Power Plant, according to a wildlife veterinarian who has studied the population since 2008… [The three changes include]:

Smaller bodies

Smaller heads and brains

Anemia: “The monkeys show a reduction in all blood components: red blood cells, white blood cells, hemoglobin, and the cells in bone marrow that produce blood components.”

Findings expressed in graphs show clear correlation between level of exposure and biological problems, such as a reduction in white blood cells.

Perhaps even more concerning is the lack of recovery observed by Dr. Hayama:

“We have taken these tests from 2012 through 2017, and the levels have not recovered. So we have to say this is not an acute phenomenon. It has become chronic, and we would have to consider radiation exposure as a possible cause,” Hayama said.

You can read the full study and previous research:

No one really knows what is going to happen in a nuclear waste land. There are so many uncertainties and contingencies but one thing is certain and that is that increased levels of radionuclides in air, water, soil, and food disrupt the established patterns of life upon which we depend.

WTO panel rules on Korea’s ban on Japanese seafood

hjkmlmù.jpg

 

September 28th. Banners and calls for government action at Seoul’s Gwanghwamun Square: “We oppose imports of radioactive, contaminated Japanese seafood.”
 
A dozen civic groups are protesting the lifting of an import ban on Japanese seafood.
“It’s been more than six years since the Fukushima nuclear disaster, but radiation-tainted water is still being released into the sea. If the government lifts the restrictions, contaminated Japanese seafood will enter Korea.”
 
Following the Fukushima nuclear disaster in 2011, the Korean government slapped a temporary import ban on Japanese food. It then extended the ban to all fishery products from eight Japanese prefectures around Fukushima in September 2013, citing safety concerns.
 
In mid-2015, Tokyo lodged a complaint with the World Trade Organization against the restrictions.
After several bilateral meetings, a dispute resolution panel was set up in Feburary 2016, and this weekthe WTO panel sent its first dispute resolution report.
 
“Yes, both Seoul and Tokyo received the panel’s interim decision on Tuesday. For now, we cannot reveal the outcome as the concerning party’s duty. The result will be made public next spring, after it’s translated into three languages. What we can say now is that we will take measures if we think the panel’s ruling poses a risk to public health.”
 
In the complaint, Japan argued the Korean government lacked an explanation and scientific proof to back its restriction measures, adding Seoul had failed respond to Tokyo’s requests to answer its questions.
 
“In 2014 and 2015, Korea dispatched experts to conduct inspections in Fukushima. But, according to what I’ve found through information disclosure requests, under pressure from the Japanese government, the team didn’t conduct inspections in deep water, oceanfloor deposits as originally planned. Such inspections are critical to finding levels of contamination.”
 
The inspection team was disbanded in 2015 without a clear reason, and there was no final report on the inspection.
Experts believe it’s highly likely Korea lost the first panel ruling.
Once the outcome is made public next year, Korea has 60 days to hold discussions with Japan, and 15 months of appeal process, if it decides to do so.
 
“The Korean government needs to see how Japan is controlling its radiation tainted water, and conduct a thorough inspection in Fukushima, including of deep seawater, to show the import ban is fair. Secondly, the Korean government needs to take active measures to release whatever the inspection team found in 2014 and 2015 to restore people’s trust.”
 
Importing food is a matter of a nation’s sovereign rights.
A number of other countries, including China, Russia, Singapore and the U.S. all have some sort of import restriction measures, with China banning imports from ten prefectures in Japan, and Russia banning not just fresh seafood, but processed seafood.
Thus, the WTO ruling could have a broader impact and give Japan the basis to claim that food produced in the Fukushima region is 99 percent safe.
 
“There’s no safety level. Food safety standards differ according to the scientific research methods and the machines you use. No matter how small, radioactive material like Cesium, which stays in a natural state for a long time, accumulates in fish. If consumed by people, there’s a possibility it can cause cancer.”
 
Following the import ban in 2011, Japanese seafood imports to Korea have slumped to less than half the level they were at before the Fukushima nuclear disaster.
Many Koreans are worried about the possible resumption of seafood imports from Japan.
 
“Then, people won’t be conscious or cautious of food from Fukushima, and I’m worried my child will eat Japanese seafood. The government should protect the public’s health.”
 
“With concerns about radioactive contamination in seafood imports from Japan, and a lack of transparency from the government, the Korean public is calling on the administration to take the necessary measures that guarantee the safety of the nation’s food supply.
Kim Hyesung, Arirang News. ”

Japan attempting to force contaminated food products onto the market

A World Trade Organization panel has apparently ruled in Japan’s favor in a dispute over South Korean restrictions on imports of Japanese seafood imposed after the 2011 Fukushima nuclear disaster, according to a source familiar with the matter.
Both sides had been informed of the panel’s decision as of Tuesday. Tokyo declined to reveal the outcome but said it was “consistent with Japan’s position.” A final report is expected to be made public by next spring.

WTO panel said to back Japan on Fukushima fish ban

Tokyo has called South Korean restrictions on seafood imports unfair
GENEVA/SEOUL — A World Trade Organization panel has apparently ruled in Japan’s favor in a dispute over South Korean restrictions on imports of Japanese seafood imposed after the 2011 Fukushima nuclear disaster, according to a source familiar with the matter.
Both sides had been informed of the panel’s decision as of Tuesday. Tokyo declined to reveal the outcome but said it was “consistent with Japan’s position.” A final report is expected to be made public by next spring.
The WTO dispute settlement process lets parties appeal panel decisions. Ryu Young-jin, South Korea’s minister of food and drug safety, told lawmakers in the National Assembly on Tuesday that the country would appeal any ruling against it by the panel “in the interest of public health.”
For Tokyo, a victory would mark progress on rolling back restrictions on imports of fish and other seafood from waters off eastern Japan. The South Korean ban, which Japan claims is unfair under WTO rules, was imposed in 2013. Japan tried and failed to talk the matter out with South Korea in 2015, prompting Tokyo to request the establishment of the dispute resolution panel.
What happens next remains unclear. South Korea’s Yonhap News Agency reported that the import ban would stay in place until at least 2019.
A number of other countries have imposed similar restrictions on Japanese seafood for fear of radioactive contamination, so the ruling could have a broader impact.

Seoul considers appeal against WTO ruling on Fukushima seafood ban

SEOUL, Oct. 18 (Yonhap) — South Korea is considering appealing the World Trade Organization (WTO) panel findings that its import restrictions on Japanese seafood after the 2011 Fukushima nuclear disaster were unfair, the country’s trade ministry said Wednesday.
Japan lodged a complaint at the WTO in 2015 to challenge South Korea’s import bans and additional testing requirements on fish caught from eight prefectures near Fukushima since 2013.
On Tuesday, WTO’s dispute settlement panel in Geneva ruled in favor of Japan and notified the two sides of the result.
“We will appeal in accordance with the WTO procedures if (its decision) is considered unfair and affects the government’s ability to safeguard the health of our people,” the Ministry of Trade, Industry and Energy said in a release. “Public health concerns are our top priority.”
Under WTO rules, South Korea has 60 days to appeal to an appellate body, which could delay imports of Fukushima-related seafood for another two years during the deliberation period.
Details of the final result will be available to WTO member nations in January and will be open to the public afterwards, the ministry said.

New study says Minami-soma as safe as Western Japan cities – do they really expect us to believe this?

On September 5, 2017, Minami-soma city made a statement on the city’s radiation levels compared to 3 cities in West Japan, which has been reported in several newspapers. It’s important to comment on this study because the statement is intended to persuade the population to return to live there.

We are publishing comments on the articles below after having discussed with M. Ozawa of the citizen’s measurement group named the “Fukuichi Area Environmental Radiation Monitoring Project“. For English speaking readers, please refer to the article of Asahi Shimbun in English. For our arguments we refer to other articles published in other newspapers – Fukushima Minyu and Fukushima Minpo – which are only in Japanese.

Here are the locations of Minami-soma and the 3 other cities.

MINAMI-SOMA, Fukushima Prefecture–Radiation readings here on the Pacific coast north of the crippled Fukushima No. 1 nuclear power plant are almost identical to those of sample cities on the other side of Japan.

The Minami-Soma government initiated the survey and hopes the results of the dosimeter readings, released Sept. 4, will encourage more evacuees to return to their home areas after they fled in the aftermath of the 2011 nuclear disaster.

A total of 100 portable dosimeters were handed out to 25 city employees from each of four cities–Minami-Soma, Tajimi in Gifu Prefecture, Fukuyama in Hiroshima Prefecture and Nanto in Toyama Prefecture. They were asked to take them wherever they went from May 29 through June 11.

The staff members were evenly dispersed with their homes in all corners of the cities they represented.

In addition, only those living in wooden houses were selected as different materials, concrete walls, for example, are more effective in blocking radiation.

In July 2016, evacuation orders for most parts of Minami-Soma were lifted, but not many residents have so far returned.

The city’s committee for health measures against radiation, which is made up of medical experts, analyzed the data.

The median value of the external radiation dosage of the 25 staff of Minami-Soma was 0.80 millisieverts per annum, while the average value was 0.82 mSv per annum, according to Masaharu Tsubokura, the head of the committee and a physician at Minami-Soma general hospital.

No significant difference was found in the three western cities.

Both figures were adjusted to include the natural radiation dose, and are below the 1-mSv per annum mark set by the national government as the acceptable amount of long-term additional radiation dosage, which is apart from natural radiation and medical radiation dosages.

The radiation doses in all cities were at levels that would not cause any health problems, according to Tsubokura.

Making comparisons with other municipalities is important,” Tsubokura said. “I am intending to leave the survey results as an academic paper.”

Our comments

1) The difference of life style between city employees and local agricultural population
As we see in the article, portable dosimeters were handed out to city employees. They
 spend most of their day time in an office protected by concrete walls which are efficient for blocking radiation as stated in the article. However, in Minami-soma, most of the population spends more time outside, very often working in the fields. Their life style is different and therefore the external radiation dose cannot be similar to those of city employees. The result of the comparison between the external radiation dose of city employees cannot be used as an argument to say that it is safe for the local population to live in Minami-soma.

2) In the article of Fukushima Minyu, it is stated that in Minami-soma the radiation dose has a wider range than in the other three cities. This means that there are hotspots, which leads to higher risks of internal irradiation.

3) The radiation dose expressed in terms of Sieverts is relevant for radioprotection when the source of radiation is fixed and identified. This is the case for most of the nuclear workers. However, in the case of Fukushima after the nuclear accident where the whole environment is radio-contaminated and the radioactive substances are dispersed widely everywhere, it is not a relevant reference for radioprotection. It is important in this case to measure surface contamination density, especially of soil.

4) 6 years and 6 months since the accident, cesium has sunk in the soil. It is thought to be between 6 and 10 cm from the surface. This means the top layer of soil from 0 to 5 cm is blocking the radiation, reducing the measures of the effective dose. However, this does not mean that the population is protected from internal irradiation, since cesium can be re-scattered by many means, by digging or by flooding, for example.

5) The reliability of individual portable dosimeters has already been raised many times. This device is not adequate to capture the full 360° exposure in radio-contaminated environments as described in point 3 above.

6) In the article, it is stated that background radiation is included in the compared values, but it does not mention the actual background radiation measurements in the 4 cities.

The Table of Fukushima Minyu

Radiation dose of the 4 cities

Screenshot from 2017-09-07 23-58-15.pngValues include the background radiation dose

 

To summarize, the sample study group does not represent the overall population. The study doesn’t include the risks of internal radiation, for which the measurement of contaminated soil is indispensible. The dosimeters are not adequate to measure the full load of radio-contaminated environments. So, the research method is not adequate to draw the conclusion to say that it is safe for the population to return to live in Minami-soma.

Small head size and delayed body weight growth in wild Japanese monkey fetuses after the Fukushima Daiichi nuclear disaster

serveimage.jpg

Abstract

To evaluate the biological effect of the Fukushima Daiichi nuclear disaster, relative differences in the growth of wild Japanese monkeys (Macaca fuscata) were measured before and after the disaster of 2011 in Fukushima City, which is approximately 70 km from the nuclear power plant, by performing external measurements on fetuses collected from 2008 to 2016. Comparing the relative growth of 31 fetuses conceived prior to the disaster and 31 fetuses conceived after the disaster in terms of body weight and head size (product of the occipital frontal diameter and biparietal diameter) to crown-rump length ratio revealed that body weight growth rate and proportional head size were significantly lower in fetuses conceived after the disaster. No significant difference was observed in nutritional indicators for the fetuses’ mothers. Accordingly, radiation exposure could be one factor contributed to the observed growth delay in this study.

Introduction

The Fukushima Daiichi nuclear power plant (NPP) disaster that occurred in March 2011 exposed a large number of humans and wild animals to radioactive substances. Several studies of wild animals in Fukushima investigated health effects of the disaster, such as morphological abnormalities in gall-forming aphids (Tetraneura sorini, T. nigriabdominalis)1 and pale grass blue butterfly (Zizeeria maha)2, hematological abnormalities in carp (Cyprinus carpio)3, and chromosomal aberrations in wild mice (Apodemus argenteus, Mus musculus)4. However, there is no research investigating long-term exposure to radiation on mammals that typically have long life-span to date. This study is the first report to observe long-term biological effects of the pre- and post-NPP disaster on non-human primates in Fukushima.

We previously studied radioactive exposure and its effect on health of Japanese monkeys (Macaca fuscata) inhabiting Fukushima City, which is located approximately 70 km from the Fukushima Daiichi NPP5, 6. After the NPP disaster, the range of radiocesium soil concentrations in Fukushima City was 10,000–300,000 Bq/m2. Hayama et al.5 investigated chronological changes in muscle radiocesium concentrations in monkeys inhabiting Fukushima City from April 2011 to June 2012. The cesium concentration in monkeys’ muscle captured at locations with 100,000–300,000 Bq/m2 was 6000–25,000 Bq/kg in April 2011 and decreased over 3 months to approximately 1000 Bq/kg. However, the concentration increased again to 2000–3000 Bq/kg in some animals during and after December 2011, before returning to 1000 Bq/kg in April 2012, after which it remained constant.

Fukushima monkeys had significantly lower white and red blood cell counts, hemoglobin, and hematocrit, and the white blood cell count in immature monkeys showed a significant negative correlation with muscle cesium concentration6. These results suggested that the short-term exposure to some form of radioactive material resulted in hematological changes in Fukushima monkey

The effects associated with long-term low-dose radiation exposure on fetuses are among the many health concerns. Children born to atomic bomb survivors from Hiroshima and Nagasaki showed low birth weight, high rates of microcephaly7, and reduced intelligence due to abnormal brain development8. Experiments with pregnant mice or rats and radiation exposure had been reported to cause low birth weight9, 10, microcephaly11,12,13, or both14, 15. We identified one similar study on wild animals16, which reported that the brains of birds captured in the vicinity of the Chernobyl NPP weighted lower compared to those of birds captured elsewhere.

The population of Japanese monkeys in Fukushima City had been systematically managed since 2008 according to a management plan based on law and regulated by Fukushima Prefecture to reduce damage to agricultural crops. Our research group studied the reproductive and nutritional status of the Japanese monkey population by performing autopsies on individuals captured and euthanized by Fukushima City17. These Japanese monkeys were the first wild primate population exposed to radiation as result of nuclear disaster. However, there was no other study either in Chernobyl or Fukushima that followed fetal development over time or compared fetal development before and after long-term radiation exposure in the same wild animal populations.

The objectives of this study were to compare changes in the fetal development of Japanese monkeys in Fukushima City before and after the NPP disaster to determine evidence of developmental delay in Japanese monkey fetuses.

Results

Radiocesium was detected in mothers’ muscle that had conceived after the NPP disaster (Table 1). Mean muscle radiocesium concentration was 1059 Bq/kg for mothers that mated in 2011 and gave birth in 2012 (n = 14), although the concentration decreased gradually in subsequent years up to 22 Bq/kg for mothers that gave birth in 2016 (n = 3). Because muscle tissue was not available prior to the NPP disaster, muscle radiocesium concentrations for individuals captured pre-disaster could not be measured. However, muscle radiocesium concentrations in wild Japanese monkeys captured in 2012 in Aomori Prefecture, which is also located in the Tōhoku region 400 km north from the NPP, were below the detection limit2, therefore, we assumed that the muscle radiocesium concentrations in the Japanese monkeys in Fukushima City prior to the disaster were also below the detection limit.

Similarly, although the air dose in the area of Fukushima City inhabited by the Japanese monkeys was 1.1 to 1.2 µSv/h in April, 2011, it has decreased, reaching 0.10 to 0.13 µSv/h in May, 2016 (Table 2). Based on these measurements, it is estimated that monkeys in this area received accumulated air doses of at least 12 mSv over the five years since the NPP disaster.

The descriptive statistics for Japanese monkey fetuses in Fukushima were shown in Table 3. The median body weight (g) and median body weight growth rate (g/mm) were significantly different between pre- and post-disaster groups (p = 0.032 and 0.0083, respectively). The mean biparietal diameter (mm), occipital frontal diameter (mm), head size (mm2), and proportional head size (mm) were significantly different between pre- and post-disaster groups (p = 0.046, 0.018, 0.014, and 0.0002, respectively). CRL was not significantly different between the two groups. Regression lines describing association of body weight and CRL in pre- and post-disaster groups were described in Fig. 1. Post-disaster regression line was significantly lower than pre-disaster regression line (p < 0.0001) (Table 4). Regression lines describing association of head size and CRL in pre- and post-disaster groups were described in Fig. 2. Post-disaster regression line was significantly lower than pre-disaster regression line (p < 0.0001) (Table 5).

The body fat index for the mothers of these fetuses was not significantly different before and after the NPP disaster (Z = 1.213; P = 0.219).

Discussion

Body weight and head size relative to the CRL were lower in fetuses conceived after the NPP disaster compared with fetuses conceived prior to the NPP disaster. Japanese monkeys in Fukushima City first conceive in fall when they were five years old and gave birth in spring when they were six years old17. Thus, we assumed that all the mothers we examined that conceived babies after the NPP disaster were continuously exposed to radiation from at the time of the disaster in 2011.

Growth retardation of the fetuses could be caused by the deterioration of the mothers’ nutritional status. However, we did not observe any difference in the body fat index of mothers pre- and post-NPP disaster. Therefore, the growth retardation of the fetuses was unlikely to be associated with to the mothers’ nutritional status. Other factors such as climate changes or food nutrient components might have affected the growth of fetuses. The limitations of this study were that we were not able to obtain samples to look at histological change that might have contributed to the cause of delayed fatal growth and the sample size were relatively small because of the nature of the sampling collection. It might have been ideal to compare monkeys from the evacuation order area to monkeys from the non-contaminated area of Fukushima; however, there was no other area such besides the one in this study that performed systematic large-scale capturing aimed at seizing hundreds of monkeys. In addition, there had been access limitations beyond the evacuation order area. For these reasons, it is impossible to replicate an equivalent study elsewhere at this time.

In experiments using mice and rats, radiation exposure has been reported to cause reduced fetal weight, microcephaly, and reduced brain mass9,10,11,12,13,14,15. However, most of these experiments involved exposing the mother to a single radiation dose at a fetal age of 10 days or later when the brain undergoes development. Such exposure may be qualitatively different from the low-dose, long-term exposure following an NPP disaster. The radiation doses in these experiments varied substantially. Hande et al.9 exposed mice to 9 mGy of 70 kilo-Volt peak X-rays at fetal ages of 3.5, 6.5, and 11.5 days, and found that birth weight was reduced relative to the control mice in all cases. Uma Devi et al.15 exposed mice to 0.25 Gy at a fetal age of 11.5 days and observed reduced head size at birth. In addition, they observed negative correlation between radiation dose and head size in fetuses exposed to 0.05 to 0.15 Gy.

The number of low birthweight children born to residents of some highly contaminated areas of Belarus increased between 1982 and 1990, after the Chernobyl NPP disaster18. Hujuel et al.19 conducted a longitudinal survey of women exposed to radiation through dental treatment who subsequently gave birth. They reported that women exposed to 0.4 mGy or more had increased risk (odds ratio 2.27) of giving birth to a child weighing 2500 g or less. Goldberg et al.20 elucidated the relationship between the level of radiation exposure as a result of medical exams prior to conception and birthweight, and found that birthweight decreased by 37.6 g for every cGy of exposure. Such medical exposure is believed to affect the mother’s gonads and endocrine glands rather than the fetus itself. There is still uncertainly to determine whether the retarded growth we observed was a direct effect of the radiation exposure.

Otake and Schull8 conducted a temporal variation study of mothers exposed to radiation by the atomic bombs in Hiroshima and Nagasaki. They did not observe any effect in newborns that had been exposed between fetal ages of 0 to 8 weeks, and the highest rates of microcephaly and other brain damage occurred in newborns exposed between fetal ages of 8 to 15 weeks. Given that the latter period was when the human brain undergoes rapid development, damage due to radiation exposure during this period might cause severe effect on fetuses.

The previous research suggested that the low birthweight and small head sizes observed in fetuses conceived after the NPP disaster were result of radiation exposure. However, we were not able to quantify the external and internal radiation dose in individual wild animals. Although radiocesium was detected in the muscles of all individuals captured after the NPP disaster, the cumulative exposure was unclear since the biological half-life of radiocesium in monkeys was approximately 3 weeks5. Furthermore, because of the small sample size, it was difficult to determine the causal relationship of exposure dosage and the effect on fetuses.

Although we showed that fetal proportional head size reduced after the NPP disaster, it was not possible to identify anatomically which part of the brain was developmentally retarded. Hossain et al.12 studied the brains of 6- to 12-month-old mice that were exposed to cobalt 60 at a fetal age of 14 days. Brain weight decreased at exposure rates of 0.5 to 1.5 Gy and the number of neurons in the hypothalamus in the CA3 region decreased significantly. We started to perform histological examination brain of fetuses and juvenile monkeys conceived after the NPP disaster to identify the regions of the brain that were developmentally retarded and the effect of retarded growth on post-natal development for further study.

Radiation levels exceeding state-set limit found on grounds of five Chiba schools

n-kashiwa-a-20170614-870x580.jpgRadiation levels exceeding the state safety limit have been detected on the grounds of five schools in Kashiwa, Chiba Prefecture.

 

Radiation levels exceeding the government-set safety limit of 0.23 microsieverts per hour have been detected on the grounds of five schools in the city of Kashiwa, Chiba Prefecture, the prefectural board of education said Monday.

Between late April and mid-May, the board officials detected radiation levels of up to 0.72 microsieverts per hour in certain areas of the schools, including Kashiwa High School and Kashiwa Chuo High School. The areas — including soil near a school swimming pool and drainage gutters — are not frequented by students, but the board closed them off and will work to quickly decontaminate them, the officials said.

Kashiwa has been one of the areas with high radiation readings since the 2011 nuclear disaster at Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 power plant.

According to NHK, the board of education had been checking the soil on the school premises in Kashiwa after radiation levels beyond the state limit were detected in shrubbery near the city’s public gymnasium. The board will announce the results of radiation tests at other schools in the prefecture around the end of July, NHK reported.

0.24 to 0.72 microsievert per hour at five schools in Kashiwa city, 47km from Tokyo

Capture du 2017-06-12 17-21-21

 

In January 2017, the Chiba Prefectural Board of Education was notified that radiation above the national standard level was measured at the Kashiwa city central gymnasium.

Following that report the Chiba Prefectural Board of Education conducted an investigation in Kashiwa city from late April to the middle of May 2017.

A radiation level exceeding the national standard of 0.23 microsievert per hour was detected on the premises of five schools in Kashiwa City, The radiation measured at 1 meter above ground level ranged from 0.24 to 0.72 microsievert.

At Kashiwa High School, Higashi Tsukuba High School and Middle School, Kashiwa Chuo High School, Kashiwanami High School and Kusanami Takayanagi High School, at places where usually no one enters: near a pool, at the back of a bicycle parking lot, etc..

The prefectural Board of Education decided to cordon those hot spots, to prohibit the entry and to decontaminate those places by soil removal.

They are also planning to conduct a radiation levels survey to the schools outside of Kashiwa city.

Fukushima Radiation, What Prospects for Humanity : a Conversation with Helen Caldicott

Caldicott.jpg

Do not go to Japan. Do not under any circumstances take your children to Japan, because you don’t know what you’re eating and where the food is sourced…

And the Japanese are trying now to export their radioactive food to London and elsewhere. Taiwan has refused to receive it. But, it’s dangerous and it’s going to continue to be dangerous for the rest of time. It’s sad.Dr. Helen Caldicott (from this week’s interview.)

Arnie Gundersen, a nuclear educator and former nuclear industry senior vice president, has referred to it as “the biggest industrial catastrophe in the history of mankind.” [1]

Six years ago this week, a tsunami, triggered by a category 9.0 earthquake, slammed into the site of the Fukushima Daiichi nuclear facility on the north east coast of the Japanese island of Honshu. The natural disaster resulted in the failure of systems keeping the reactor cores and spent fuel rods cool, leading to core meltdowns in three of the plant’s reactors, as well as damage from consequent hydrogen explosions. [2]

Enormous quantities of radioactive particles were released into the atmosphere and the water table leading to the Pacific Ocean. Approximately 170,000 people in the vicinity of the plant were immediately evacuated.

The World Health Organization downplayed the health risks from the catastrophe, concluding in their 2013 Health Risk Assessment from the nuclear accident that the risks of contracting certain cancers in certain sex and age groups were only “somewhat elevated.” The report also concluded “no discernable increase in health risks from the Fukushima event is expected outside Japan.” [3]

Nevertheless, a health management survey examining 38,000 children in Fukushima found three children diagnosed with thyroid cancer. The natural incidence is one in one million. [4]

Further, a December 2011 peer-reviewed report in the International Journal of Health Sciences found that in the 14 weeks immediately following the event, there were 14,000 excess deaths in the United States connected with radio-active fall-out from the Fukushima meltdowns. [5]

 The Japanese government has been so successful in its efforts to assuage the concerns of the wider public that Prime Minister Abe was able to secure Tokyo as the site for the 2020 Olympic Summer Games! As of this month, the Abe government ends its housing subsidies to people evacuated from the area proximate to the nuclear facility, forcing those fearful of the lingering radiation to fend for themselves abroad. [6][7]

The nuclear accident may have profound consequences for all humanity, and possibly all life on Earth, yet the severity of the situation doesn’t seem to merit major headlines.

On this, the sixth anniversary of the start of the Fukushima crisis, we spend the hour with world renowned nuclear watchdog, Dr. Helen Caldicott.

 In this interview, conducted and recorded on International Women’s Day, Dr. Caldicott talks about the high radiation reading recently recorded at Unit 2, efforts to contain the radioactive water spilling out of the facility, projected health risks from the cesium, tritium, strontium and other isotopes spewing from the site and much, much more. Caldicott also extends the discussion to talk about Canada’s role in nuclear proliferation and the threats posed by the new Trump Administration and Cold War atmosphere in which it is situated.

 Dr. Helen Caldicott is a physician and co-founder of Physicians for Social Responsibility. She is a nominee for the Nobel Peace Prize, the recipient of the 2003 Lannan Prize for Cultural Freedom, and author or editor of several books including Nuclear Madness: What You Can Do (1979), If You Love This Planet: A Plan to Heal The Earth (1992)The New Nuclear Danger: George W. Bush’s Military-Industrial Complex(2001), and Crisis Without End -The Medical and Ecological Consequences of the Fukushima Nuclear Catastrophe (2014). She is currently the president of the Helen Caldicott Foundation (NuclearFreePlanet.org). Her latest book, Sleepwalking to Armaggedon: The Threat of Nuclear Annihilation will be available in bookstores in July, 2017.

15,550 Bq / kg radioactive cesium school rooftop sludge in Chiba prefecture

gkhlmùm.jpg

Noda city (Noda-shi on the map) is located in Chiba prefecture, at the northern doorstep of Tokyo.

Noda City announced on January 24 that more than 15,550 Becquerel of radioactive cesium exceeded the criteria of designated waste (more than 8,000 bq per 1 kilogram) from the rooftop sludge of Municipal Nittsuka Elementary School. It is the first time that sludge exceeded the standard value in the city. The city already removed the sludge, in accordance with procedures as specified waste based on the Special Measures Law.

In response to the high radiation dose measurements found in Kashiwa city public property site this month, the city started inspection of sludge etc. and dose measurement at 300 public facilities. The country’s decontamination standard is 0.23 microsieverts per hour with a measurement height of 1 meter (50 centimeters for children-related facilities), but the city has independently set the measurement height to be a more severe 5 cm. There are no places that have exceeded city standards so far.

Meanwhile, on the 14th and 15th, they measured sludge on the roof of 12 elementary and junior high schools that were the subjects of solar panel roofing projects. As a result, they found doses exceeding city standards at five schools, up to 0.85 micro-Sievert was measured. City removed the sludge and checked radioactive cesium concentration. Only the sludge of Yotsuka-sho, had concentration of cesium exceeding the standard value of designated waste.

The removed sludge is temporarily stored at a temporary storage place surrounded by containers on the city hall premises. Approximately 5 cubic meters of targeted waste is treated, and four schools sludge which cesium concentration was found within the standard value were treated as general waste.
