The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Six years later, some workers at Fukushima nuclear plant say they can do without protective gear

This article actually says that people observing from a nearby hill were exposed to only 150 microsieverts per hour. If that number is not a careless misprint, it’s actually a huge number. A person living on that hilltop would be exposed to 1,314 millisieverts per year (if I calculated correctly), way above the legal limit which was increased to 100 millisieverts per year after the accident.


Workers walk past cherry trees at the Fukushima No. 1 nuclear power plant on April 14. The plant operator said visitors do not need to wear special protection gear in most parts of the premises as radiation levels have fallen.

OKUMA, FUKUSHIMA PREF. – At the facility on the Pacific Coast, people in casual clothes stroll under cherry trees in full bloom.

Hot meals made with local ingredients are served for ¥380 at a cafeteria. Cold drinks, snacks and sweets are available at a convenience store.

This scene is not unfolding at a popular tourist site, but at the Fukushima No. 1 nuclear power plant, which was rocked by a magnitude-9 earthquake and the ensuing tsunami on March 11, 2011.

Accompanied by officials from Tokyo Electric Power Company Holdings Inc., a group of reporters was given access to the power station earlier this month.

Six years have passed since the world’s worst nuclear disaster since Chernobyl in 1986.

Efforts to remove radioactive debris and to cover tainted soil with materials like mortar have helped decrease the radiation at the plant, allowing workers to wear regular uniforms at about 95 percent of the site.

Tainted water has been moved to more secure welded tanks, replacing weaker ones made of steel sheets and bolts, reducing leaks.

Visitors can overlook the four reactor buildings from a hill about 80 meters from the facility, where core meltdowns hit reactors 1, 2 and 3. Hydrogen explosions heavily damaged the buildings for units 1, 3 and 4, which have since received new facades.

On the hill, the radiation in the air was 150 microsieverts per hour, less than the amount received during a round-trip flight between Tokyo and New York. Tepco says there is no health hazard here as long as you wear masks and helmets and keep your stay short. Workers once needed to change into tightly woven clothing at the J-Village soccer training center about 20 km away before entering the Fukushima complex. But that burden has been lifted.

About 7,000 workers — 6,000 from construction, electronics and machinery companies and 1,000 from Tepco — work at the power station to deal with the aftermath of the meltdown and decommission the reactors.

Our near-term goal is to create a place where they can work without worries,” said Daisuke Hirose, a spokesman for Tepco’s Fukushima No. 1 Decontamination & Decommissioning Engineering Co.

There are now 400 cherry trees at the facility. Before the disaster, there were 1,200, and local residents were invited to enjoy cherry blossoms every spring, Hirose said. Now, workers walk with smiles under a tunnel of trees, greeting passers-by.

In May 2015, a nine-story rest house with meeting spaces and shower rooms opened. A convenience store was added last year.

At a 200-seat cafeteria, hot meals made with Fukushima produce are delivered from a central kitchen in the town of Okuma, about 9 km from the plant.

I used to eat cold rice balls,” a worker on a lunch break said. “Hot meals make me happy and motivate me to work.”

The plant, which stands on a 3.5-sq.-km site about 230 km northeast of Tokyo, started up in 1971.

Since the radiation has dropped sharply at the facility, about 10,000 people per year, including journalists from the United States, Europe and Asian countries, have visited. Last year, high school students dropped by.

After the two-hour tour, a dosimeter carried by a reporter showed she was exposed to only 40 microsieverts, less than the amount from a chest X-ray.

Although the working environment has certainly improved, the fate of the plant is far from clear.

Decommissioning the crippled reactors is expected to take 30 to 40 years. The utility is aiming to begin removing fuel debris from one reactor by the end of 2021, but so far it has failed to even ascertain the condition inside the reactors.

A lot of rubble remains in many of the buildings on the seaside, keeping alive fears of a quake-tsunami catastrophe like the one that struck six years ago.

A frozen underground wall has seen only limited success in preventing groundwater from flowing into the reactor and turbine buildings, regulators have said, acknowledging that the facility is still a perpetual generator of tainted water.

Tepco is also struggling to dispose of tainted waste, such as used protective garments, gloves and socks. It has burned 1,500 tons of such waste while monitoring the radiation in the smoke. It still had 70,000 cu. meters of garbage as of the end of February.

Through legislation, we are prohibited from taking radioactive contaminated garbage outside the facility even after we incinerate it. We have to continue the fight against garbage and ash,” Hirose said.

Public confidence in Tepco has been shaky in the wake of the meltdowns, and even now, nearly 80,000 residents are unable to return to their homes near the plant.

We have caused it,” Hirose said. “We have to make every effort to create a place to which people want to return. Nobody wants to live where the safety and security of workers are not ensured.”

The Nihonmatsu Declaration on the Risks of Exposure to Low Doses of Ionising Radiation

A statement by participants to the 6th Citizen-Scientist International Symposium on Radiation Protection 7–10 October 2016in Nihonmatsu, Japan

Over recent years, some interested parties have claimed that human exposure to low doses100 mSv/mGy or lessof ionising radiation does not confer an increased risk of cancer, or that the risk is so small that it cannot be estimated.

Our understanding of the risks of ionising radiation leads us to conclude that:

The accrued epidemiological data do not support there being a threshold of risk at 100 mSv for the induction of cancer. [1-11] [12-14]. Most of the available evidence together with mechanistic considerations, point to linearity of dose response at both high and low dose-rates.

Direct measurement of risk below 100 mSv [1-5, 7, 9] and extrapolation from higher doses [3, 5, 6, 10, 11, 15], support the use of the linear dose response model for doses less than 100 mSv and for the estimation of risks for the protection of public health after nuclear accidents.[3]

The INWORKS study of workers is particularly important because the mode of exposure is similar to that which will be experienced by returning evacuees. It provides important information in re- lation to the risks in the dose range 0 to 100 mGy. Over this range the risk0.8 per Gyis higher, but not significantly so, than the overall estimate of 0.48 per Gy.This estimate is not influenced by the slope at higher doses.The paper states: “INWORKS thus provides supportive evidence for a positive association between radiation dose and all cancer other than leukaemia, even if less precise when analyses are restricted to data for the 0-100 mGy dose range.”

This position is consistent with:

The 2000 report of the United Nations Scientific Committee on the Effects of Ionising Radiation [16] [17]UNSCEAR, subsequently endorsed in their 2012 White Paper [18] and the 2012 analysis of the 2006 BEIR VII report from the US National Academy of Sciences [6] the Japanese bomb survivor data .

The World Health Organisation report of 2013 [19] on the Fukushima accident.

We conclude that a recommended “reference level” of 20 mSv/year for returning evacuees from areas adjacent to the Fukushima Daiichi accident will entail an increased lifetime risk of cancer, par- ticularly for those exposed as children.

The 6th Citizen-Scientists International Symposium on Radiation Protection

go beyond silenced science.jpg


Founded in 2011, The Citizen-Scientist International Symposium on Radiation Protection CSRP, is a non-profit organization established by citizens and scientists concerned about the issue of low dose exposure. Since the explosion at Fukushima’s nuclear plant in March 2011, CSRP has held several workshops each year, as well as an annual international symposium, on radiation protection from the viewpoint of citizens, inviting researchers and citizens from both Japan and overseas to find the most effective ways to deal with the issue together. The 6th CSRP symposium was held in Nihonmatsu, Fukushima Prefecture, between October 7 and 10, 2016for full details of the symposium, please refer to our website The symposium published two recommendations ̶ the “Conclusions” and the “Nihonmatsu Declaration on the Risks of Exposure to Low Doses of Ionizing Radiation” ̶ based on four days of presentation sessions and roundtable discussions. We sincerely hope that discussions by both experts and members of the public on this issue allow us to deepen our understanding of the situation and better able us to recommend the wisest policy decisions in regard to management of the disaster, beyond positions and paradigms, for better radiation protection measures.

The 6th Citizen-Scientists International Symposium on Radiation Protection

For further scientific elucidation of health risks due to radiation exposure caused by the 2011 TEPCO Fukushima Daiichi nuclear power plant accident, in order to practice better public protection and response measures


Radiation protection measures should be carried out in agreement with the research of scientists from rel-evant disciplines, based on the underlying epidemiological findings. In particular, there are a number of epi-demiological evidences supporting the linear non-thresholdLNTmodel that states that the health effects of ionizing radiation have no safety threshold and are linearly proportional to the exposure dose even at a cumulative dose lower than 100 millisievertmSv.All the radiation protection measures should presuppose this model from a precautionary standpoint.Note 1

Recommendations to the Japanese Government and relevant parties

Expansion of thyroid cancer examination and enhancement of support

Several epidemiological views conclude that the results of the Fukushima prefectural health management survey are already clearly showing the frequent occurrence of thyroid cancer. Considering the diagnosed tu-mor sizes and the surgery cases that resulted from the survey, the currently practiced thyroid examination is consistent with one of the objectives of the survey, “early detection, early treatment.” The survey should be expanded, and the support should be enhanced for people suffering from thyroid cancer and other thyroid abnormalities.Note 2

Expansion of health survey

Health protection must be provided not only to the affected residents, but also to the people who are at risk of exposure to radiation while carrying out accident-related work, such as the nuclear plant workers and the off-site decontamination workers. The survey of health effects should be expanded to these people in or-der to determine what damages are being caused by radiation exposure, whether the current measures are effective enough and what should be done to improve the situation.Note 3

Respect of the victims’ rights

The emigrated ex-residents or the evacuees should not be forced to return to their hometowns. Those who wish to stay evacuated or emigrated, those who wish to evacuate or emigrate hereafter, or those who want to return to their hometowns, as well as those who have decided to stay in their hometowns despite the ac-cumulating exposure dose — all of the parties should be supported so that they can build the life they de-sire, all while avoiding radiation exposure as much as possible.Note 4

Revision of risk communication

In order to improve the current social environment that dissuades the victims from expressing their con-cern about the health effects of radiation, it is necessary to revise the “risk communication” measures led by the central and the local administrative authorities. Measures that aim to persuade the victims of the small risk of health effects without provinding sufficient evidence and impelling them to act as the authorities want, should be revised.Note 5

Education and public information on nuclear power and radiation

School teaching materials and learning places are provided from the pro-nuclear standpoint, unilaterally stressing the safety of nuclear power plants and downplaying the risk of health effects. Instead, the stand-point of those who bear the riskaccident victims, workers and future generationsshould be taken into ac-count fully.Note 6

Role of citizens and scientists

Citizens, including scientists, researchers and media professionals, are requested to promote an open dia-logue in which each party accomplishes its original mission for the pursuit of truth. Together, the victims and all the people involved are expected to create a living environment and public space that enable each of them to express what they really think and feel, to form a consensus, and thus to give rise to mutual trust. Note 7


Note 1On this issue, a separate joint statement by the epidemiologists who participated in the 6th Citizen-Scientist Symposium on Ra-diation Protection is to be published.

Note 2It is necessary to re-examine the thyroid surveys conducted on those who were 18 years old or younger at the time of the acci-dent, by expanding the rangesages and regionsand frequency of the surveys. Cases of thyroid cancer diagnosed by examinations other than the Fukushima prefecture health management survey should be disclosed, including those diagnosed in other regions that may also suffer from radiation effects. Several municipalities located outside the Fukushima prefecture indeed do carry out their own surveys. In addition, it is required to examine thyroid abnormalities other than cancer and to publish the results.

Five years after the accident, when the health effects of radiation exposure are now expected to emerge, the appearance instead, of ar-guments aiming to reduce the thyroid surveys is an issue. Building a debate based on the unsound concept of the “negative effects of the survey” does not appear as a scientifically driven decision. It is historical fact that the delay after which thyroid cancer appears after exposure to radiations, originally estimated to 10 years or more based on data from the Hiroshima and Nagasaki A-bomb survivors, had to be revised to five years after the Chernobyl nuclear accident. Continuing the survey is thus crucial because it ties into the issue of future compensation. Therefore, the review committee for the Fukushima prefectural health management survey should not be limit-ed by past ideas but should take new data and findings into full consideration.

Studies should be promoted to estimate how much irradiation happened just after the accident, and the results should be made public. As was discussed at the 5th International Expert Symposium in Fukushima on Radiation and HealthSeptember 2016, data on the contamination by iodine-131 are scarce. The only way to determine the initial exposure dose is to investigate the existing contamination by iodine 129 and other fission products in the environment and to reconstruct the initial dose. Studies need to be extended to regions outside the Fukushima prefecture, because contamination spreads in wide areas in Eastern Japan as shown by results from the air-borne monitoring of the Ministry of Science and TechnologyMEXTand the Nuclear Regulatory Agency.

Note 3The Fukushima prefectural health management survey has been criticized from the very beginning for its narrowness of appli-cation. For example, blood testing, whose importance has been emphasized in the areas affected by the Chernobyl accident, has been treated lightly in the case of the Fukushima Daiichi nuclear power plant accident. Moreover, given that contamination has spread to ar-eas beyond the border of Fukushima prefecture, it is difficult to understand why the comprehensive health check is limited to evacua-tion zones in Fukushima prefecture. Cancer registration data and other medical information essential for comparative studies of the health status in the affected areas are not made public. Concerns have been expressed about the exposure management of subcon-tracted workers. A re-examination of the health care system for all workers at risk of radiation exposure, including the off-site cleanup workers is imperative. The fact that the Government and TEPCO have failed to disclose necessary information, has given rise to the suspicion that they might be concealing inconvenient information. They are required to take action to address the spreading distrust.

Note 4The current policy promoted by the government under the name of “reconstruction” is laying a disproportionate emphasis on the return of evacuees to their hometowns, through the prompt cancellation of evacuation orders and while neglecting support towards victims who desire to emigrate or to remain evacuated. The government has announced the cut off, in March 2017, of the provision of free housing for what they call “voluntary evacuees”evacuees from outside the evacuation order area. A similar policy is expected to be applied to evacuees from the current evacuation order areas, once the orders are lifted. Such policies leave no choice to the victims who wish to remain evacuated and avoid further radiation exposure, but to return to their hometowns. Meanwhile, long-term support is needed for those victims who are living in contaminated regions, inside or outside the Fukushima prefecture, including support to resi-dents who wish to evacuate hereafter.

Note 5The government’s so-called “risk communication” currently underplays the health effects of radiation exposure caused by the nuclear power plant accident and merely consists in delivering basic knowledge of radiation while claiming that the risks are small, of-ten comparing the health risk of low level radiation to those of medical radiation, smoking, and obesity. This “risk communication” activ-ity has been nothing but a unilateral delivery of information that highlight optimistic views on the risk of radiation exposure. It has failed to install a dialogue that considers the diverse points of view held by the affected residents.

In particular, the conventional government-led “risk communication” has created a social atmosphere in which choosing to avoid being exposed to low-level radiations for long-term safety, is regarded as “wrong”. Victims who wish to emigrate or to remain evacuated from areas where exposure is possible, or those who desire to avoid as much radiation as they can from the food, clothing and shelter even though they chose to remain in their regions, all of them are repressed from expressing their concerns. At times, this causes conflict and cleavages between family members, friends and neighbors.

Intrinsically, “risk communication” should consider the wide range of opinions that exist regarding the risks and, through dialogue be-tween experts and residents, it should elaborate a set of measures that are adapted to each resident’s lifestyle. Initiatives such as col-lecting straightforward scientific data that is useful for avoiding exposure in daily life, illustrate the importance of mutual learning and common efforts between residents and experts.

Note 6In public teaching materials, such as the supplementary reader on radiation issued by MEXT in 2014, the instructional materials issued by the Fukushima Prefectural Board of Educationthe 1st to the 5th editionsin 2011-16, and the exhibition of the Exchange BuildingKomyutan Fukushimainaugurated by the Fukushima Prefectural Environmental Innovation Center in July 2016, there is al-most no explanation on the official limits of radiation exposure doses, including those in radiation controlled areas5.2 mSv/year, the additional exposure for the general public1 mSv/yearand those of the evacuation order area20 mSv/year. Nor is there any expla-nation on emergency radiation protection measures such as the administration of stable iodine, or on the Nuclear Accident Child Vic-tims’ Support Law, enacted in 2012 to protect the victims’ rights.

Note 7Since the beginning of the accident, not only the information needed in order to avoid radiation exposure was insufficiently dis-closed, but also the voices of victims were not reflected in the policy decision process related to radiation protection. In order to devise countermeasures that reflect the voices and needs of the most affected victims, it is also required on the side of the citizens, to make opportunities for communication, that is, dialogues widely involving citizens, including scientists, researchers, media, etc.

6th Citizen-Scientist International Symposium on Radiation Protection Date: Friday, October 7 – Monday, October 10, 2016


From the Reality of Chernobyl and Fukushima

Date: Friday, October 7 – Monday, October 10, 2016
Venue: Main Hall, Fukushima Gender
 Equality Centre 1-196-1 Kakunai, Nihonmatsu, Fukushima, 964-0904

The Citizen-Scientist International Symposium on Radiation Protection (CSRP), a politically, financially, ideologically and religiously independent non-profit organization, has been committed to keeping to minimum the damages on health and environment caused by the Tokyo Electric Fukushima Daiichi Nuclear Power Plant disaster that followed the Great East Japan Earthquake and Tsunami in March 11, 2011.

CSRP has been inviting administrative officials, researchers, NGOs, member experts of governmental inquiry commissions and international organizations working on radiation protection, etc. Since around the 3rd CSRP, this approach has started to bear fruit, because scientists and other stakeholders with different positions and paradigms began to share the same table of discussion, thus gradually making possible constructive exchange of views.

In the course of this approach, however, we began to encounter a new challenge that may concern the premise of the CSRP; the deeper we got into scientific discussion, the higher the hurdle for participation got for the general public, especially for younger generations. Also, the diversity of voices were to be alienated from pointed scientific discussions that are decisive for the decision-making of the radiation protection of the general public. This lead us to some interrogations : “Isn’t ‘science’ given too much importance in decision-making?”; “Is ‘science’ the only way for citizens to bring today’s situation under their power?”

While always continuing to examine new scientific findings with respect to health, environmental and social impacts of low-dose exposure, we added the theme of “Between Art and Science” to the 5th symposium last year, exposed various art works inspired by nuclear power and nuclear disasters, and organized a panel discussion with artists and scientists. This was the CSRP’s new attempt to question “science” and “scientificity” with a view to reexamining the relationships between science, art and philosophy before and after the modernity. The 6th CSRP of this year, held in the city of Nihonmatsu, Fukushima Pref., will collaborate with the Institute of Regional Creation by Arts, the University of Fukushima, to cosponsor the Fukushima Biennale 2016. We hope this new attempt will bring new visions to the participants.

As a place to learn and make full use of new findings exploring the effects of low-dose radiation exposure accumulating day by day, and to think together about the rights of people facing the consequences of the nuclear accident and about what epidemiology and public health should do in order to minimize the damage, we open the 6th Citizen-Scientist International Symposium on Radiation Protection.

Iodine jelly to be handed out to infants living within 30 km of nuclear plants



As a reminder:

A fallout, is the residual radioactive material propelled into the upper atmosphere following a nuclear reaction conducted in an unshielded facility, so called because it “falls out” of the sky after the explosion and the shock wave have passed. It commonly refers to the radioactive dust which can also originate from a damaged nuclear plant. Fallout may take the form of black rain (rain darkened by particulates).

This radioactive dust, consisting of material either directly vaporized by a nuclear blast or charged by exposure, is a highly dangerous kind of radioactive contamination.

Some radiation taints large amounts of land and drinking water causing formal mutations throughout animal and human life.

Iodine tablets only protect the thyroid gland from the Iodine 131, it does not protect anyone from the other occuring fallout radionuclides: 91Sr, 92Sr, 95Zr, 99Mo, 106Ru, 131Sb, 32Te, 134Te, 137Cs, 140Ba, 141La, 144C etc. Iodine 131 has also a very short half-life, 8 days, meaning a full life of 80 to 140 days, whereas most of the other fallout radionuclides have a much longer life span. By example  Cesium 134 has a half life of 2 years, a full life of 20 to 30 years, Strontium 90 a half life of 28,8 years, a full life of 288 to 432 years, Cesium 137 a half life of 30 years, a full life of 300 to 450 years.

Another thing, even if the population with the Fukushima catastrophe was only evacuated within a 30km radius, the Fukushima March plume has spread heavily within a 90km radius and less heavily up to a 250km radius.

Iodine jelly to be handed out to infants living within 30 km of nuclear plants

The Cabinet Office said it will soon start distributing iodine jelly to infants living within 30 km of nuclear power plants in a bid to protect their thyroids from possible radiation exposure in the event of a nuclear disaster.

According to the office, about 110,000 infants qualify for the iodine jellies.

There are 21 prefectures where the 30-km radius applies. In addition, infants living within three other prefectures — Kanagawa, Osaka and Okayama — which have nuclear fuel processing facilities are also part of the initiative.

Some local governments have been distributing iodine tablets to all residents for over three years, including in a tablet form for infants that would have to be crushed and mixed with syrup in the event of an accident. But to date this had not been in an iodine jelly form.

The local governments will receive about 300,000 packages, starting as early as this fall, which have a shelf life of three years, the Cabinet Office said.

There are two types of iodine jelly: one for babies under 1 month old and another for those over 1 month and up to 3 years.

Taking the jelly or tablets is supposed to stop the thyroid glands from absorbing iodine contained in radiation in the event of a nuclear disaster, as iodine tends to accumulate in the thyroid.

CSRP 2015 – The Fifth Citizen-Scientist International Symposium on Radiation Protection


Beginning in March 2011, the Tokyo Electric Fukushima Daiichi nuclear power plant catastrophe continues even now with no end in sight. We have sought out ways to reduce even a little, or possibly prevent, health effects due to radiation exposure. Whether radiation exposure leads to health effects, or what the potential health effects might be, has generated much interest in our society. However, up to now, no discussion has been openly carried out amongst scientists with various viewpoints. The nuclear power plant accident and the dispersed radioactivity exert influences over extensive social areas, affecting individuals as well as the society. What is called for now is societal decision-making regarding such influences for the purpose of radiation protecton, through discussions between the victims, the political decision-makers, the researchers, and the non-governmental organizations.
Currently, the exposed and the highly exposed human populations are either ignored by the government or they become inadvertent subjects of observation by scientists, while silently and helplessly observing incidences of illness creeping up within themselves. Epidemiological studies, deemed essential in putting public health into practice, are not cold science by any means. The purpose of epidemiological studies should include, in addition to the elucidation of frequency and causes of illnesses, the creation of frameworks to minimize health effects by reducing or preventing them. Furthermore, the true goal of epidemiological studies is for them to be utilized in reducing or preventing societal effects which could worsen the catastrophe.

What approaches are needed for science to become a survival tool for humans in the challenge of radiation protection? We shall think about this issue together at the Fifth Citizen-Scientist International Symposium on Radiation Protection,

On Day 1 of the symposium, we will approach this issue from the diverse intellectual interactions between science and art.

On Day 2, we will explore epidemiology as a science in addition to a general overview of radiation protection measures based on the latest biological findings.

Lastly, on Day 3, we will verify from societal aspects what language, law and ethics are necessary in order to put such measures into practice.
