Comparisons of the large nuclear accidents that occurred at the nuclear power plants in Chornobyl and Fukushima usually focus on the emission of radionuclides, the contamination area, doses to the public and liquidation workers, etc. However, little attention has been paid to various factors that affect decisions regarding the future development of these territories, such as the sociopolitical and economic situation in the countries during the accident and at the present time, the density and structure of the population, climate change, media coverage, and accessibility of information to the public. This article attempts to discuss the above factors, speculates about the paths for future development of both exclusion zones, and suggests the most promising areas for joint research in the future.

This paper does not necessarily reflect the views of the International Commission on Radiological Protection. Ten years have passed since the accident at Fukushima Daiichi nuclear power plant, and radioactive substances contained in agricultural products and marine products are now below detectable levels. Amidst this, the testing stance is changing from one that guarantees safety to one that guarantees relief, and testing is being reduced for financial reasons. Moreover, the sense of resistance and concern towards food products produced in Fukushima Prefecture is reducing. Anxiety has been reducing along with the development of the inspection system, the inspection results, and the passage of time. However, although there have been fewer requests, demands, and claims to avoid products from Fukushima Prefecture since immediately after the accident, there is a tendency for consumer trends to be forcefully 'surmised'. As a result, the problem of reputational damage, such as the fact that the market ranking of rice and beef has not recovered, remains an issue. [ABSTRACT FROM AUTHOR]

At the time of the accident at Fukushima Daiichi nuclear power plant in 2011, I was living in Iwaki City with my two children and my husband. With our home damaged by the tsunami and the deteriorating status following the situation at the nuclear power plant, we spent 2 years as evacuees before returning to Iwaki City. Subsequently, I decided to work as a radiation counsellor in the Suetsugi district of Iwaki City. I would like to describe my experience of taking measurements and helping to communicate with the residents while respecting the lives of local people. [ABSTRACT FROM AUTHOR]

Since the accident at Fukushima Daiichi nuclear power plant, there has been a focus on the impact of low-dose radiation exposure due to nuclear disasters and radiology on human bodies. In order to study very low levels of impact on the human body from low-dose radiation exposure, a system with high detection sensitivity is needed. Until now, the most well-established biological radiation effect detection system in the field of emergency radiation medicine has been chromosomal analysis. However, chromosomal analysis requires advanced skills, and it is necessary to perform chromosomal analysis of a large number of cells in order to detect slight effects on the human body due to low-dose radiation exposure. Therefore, in order to study the effects of low-dose radiation exposure on the human body, it is necessary to develop high-throughput chromosome analysis technology. We have established the PNA-FISH method, which is a fluorescence in-situ hybridisation method using a PNA probe, as a high-throughput chromosome analysis technique. Using this method, the detection of dicentrics and ring chromosomes has become very efficient. Using this technology, chromosomal analysis was performed on peripheral blood before and after computed tomography (CT) examination of patients at Hiroshima University Hospital, and it was possible to detect chromosomal abnormalities due to low-dose radiation exposure in the CT examination. Furthermore, it was shown that there may be individual differences in the increase in chromosomal abnormalities due to low-dose radiation exposure, suggesting the need to build a next-generation medical radiation exposure management system based on individual differences in radiation sensitivity. If techniques such as chromosomal analysis, which have been used for biological dose evaluation in emergency radiation medicine, can be used for general radiology, such as radiodiagnosis and treatment, that will be a contribution to radiology from an unprecedented angle. This article will discuss the clinical application of new biological dose evaluation methods that have been developed in the field of emergency radiation medicine. [ABSTRACT FROM AUTHOR]

After the accident at Fukushima Daiichi nuclear power plant on 11 March 2011, radioactive materials were released into the atmosphere resulting in environmental contamination. Following the implementation of environmental decontamination efforts, the Radiation Dose Registration Centre of the Radiation Effects Association established the radiation dose registration system for decontamination and related workers to consolidate and prevent the loss of radiation records. This article presents statistics on the radiation doses of decontamination and related workers using official records. Since approximately 10 years have passed since the accident in Fukushima, the types of work conducted in the affected restricted areas have changed over time. Therefore, changes in radiation dose for each type of work and comparisons with nuclear workers are presented. [ABSTRACT FROM AUTHOR]

This paper does not necessarily reflect the views of the International Commission on Radiological Protection. This article describes the institutional structure established for decommissioning Fukushima Daiichi nuclear power plant. To deal with the aftermath of the unprecedented nuclear accident in Fukushima, several responsible institutions such as Ministry of Economy, Trade and Industry (METI), Ministry of Education, Culture, Sports, Science and Technology (MEXT) have worked together at the initiative of the Government of Japan. In this structure, Tokyo Electric Power Company Holdings (TEPCO) implements the decommissioning due to its legal responsibility, while the essential direction and milestones are set by the Nuclear Emergency Response Headquarters of the Government of Japan. Nuclear Damage Compensation and Decommissioning Facilitation Corporation, a government-affiliated organisation, oversees and facilitates the decommissioning by TEPCO, and the Nuclear Regulatory Authority regulates safety from an independent standpoint. The main basic elements essential for the success of this long-term project have been developed, such as the technical strategy, financial system, and organisational capability. Decommissioning is making progress. [ABSTRACT FROM AUTHOR]

Japanese environmental sociology has developed many original perspectives, including the social structure of victims, the benefit versus victimized zone theory, and life environmentalism. Developments in the field can be divided into three stages. The first, to 2001, is characterized by the early organizing of environmental sociologists, including the establishment of the Japanese Association for Environmental Sociology (JAES), and its accompanying journal, and a focus on local environmental destruction case studies. The second, to 2011, is characterized by the institutionalization of the field, while the third was triggered by the 2011 Tohoku earthquake and tsunami and the Fukushima nuclear disaster. The third stage is currently one of diversification and a crisis of academic identity. [ABSTRACT FROM AUTHOR]

Between the decline of mass protests in the 1970s and the Great East Japan Earthquake and Fukushima nuclear meltdown in the 2010s, which resulted in the resurgence of mass demonstrations, social movements were widely regarded as uncommon in Japan. In this essay, the author reviews Japan's social movement studies in the last decade, focusing on the influence of the lack of mass protest since the 1970s on scholarly interests. The essay examines the following four topics: (1) slow responses to the resurgence of mass demonstrations in post-3.11 Japan, (2) quick responses to the rise of the radical right movement, (3) the emergence of cynical approaches to studying social movements, and (4) the redemption of the history of Japan's postwar social movements. Despite some twists and turns, we can see how social protests are a perpetual element of Japanese society that sociologists study as a common phenomenon. [ABSTRACT FROM AUTHOR]

Six and a half years after the accident at Fukushima Daiichi nuclear power plant, an area of existing exposure situation remains. One of the main concerns of people is the higher level of ionising radiation than before the accident, although this is not expected to have any discernible health effect. Since the accident, several 'abnormalities' in environmental organisms have been reported. It is still not clear if these abnormalities were induced by radiation. It appears that the impact of the released radioactivity has not been sufficient to threaten the maintenance of biological diversity, the conservation of species, or the health and status of natural habitats, which are the focus in environmental protection. This highlights a difference between the protection of humans and protection of the environment (individuals for humans and populations/species for the environment). The system for protection of the environment has been developed with a similar approach as the system for protection of humans. Reference Animals and Plants (RAPs) were introduced to connect exposure and doses in a way similar to that for Reference Male and Reference Female. RAPs can also be used as a tool to associate the level of radiation (dose rate) with the biological effects on an organism. A difference between the protection of humans and that of the environment was identified: an effect on humans is measured in terms of dose, and an effect on the environment is measured in terms of dose rate. In other words, protection criteria for humans are expressed in term of dose (as dose limits, dose constraints, and reference levels), whereas those for the environment are expressed in terms of dose rate (as derived consideration reference levels).

The accident at Fukushima Daiichi nuclear power plant on 11 March 2011 released radioactive material into the atmosphere, and contaminated land in Fukushima and several neighbouring prefectures. During rehabilitation, it is important to accurately understand and determine individual external doses to allow individuals to make informed decisions about whether or not to return to the affected areas. Personal dosimeters (D-Shuttle), used together with a global positioning system and geographic information system device, can provide realistic individual external doses and associated individual external doses, ambient doses, and activity patterns of individuals in the affected areas of Fukushima. This study involved more than 250 affected residents. The results help to determine realistic individual external doses, and corresponding time-activity patterns and airborne monitoring ambient dose rates, which can be used to predict future cumulative external doses after residents return to their homes in evacuation areas. In addition, insights gained by the study can help to explain the role of individual external dose measurements for affected residents in postaccident recovery, based mainly upon the experience gained in measuring, assessing, and communicating individual external doses.

The accident at Fukushima Daiichi nuclear power plant occurred following the huge tsunami and earthquake of 11 March 2011. After the accident, there was considerable uncertainty and concern about the health effects of radiation. In this difficult situation, emergency responses, including large-scale evacuation, were implemented. The Fukushima Health Management Survey (FHMS) was initiated 3 months after the accident. The primary purposes of FHMS were to monitor the long-term health of residents, promote their well-being, and monitor any health effects related to long-term, low-dose radiation exposure. Despite the severity of the Fukushima accident and the huge impact of the natural disaster, radiation exposure of the public was very low. However, there were other serious health problems, including deaths during evacuation, increased mortality among displaced elderly people, mental health and lifestyle-related health problems, and social issues after the accident. The Nuclear Emergency Situations - Improvement of Medical and Health Surveillance (SHAMISEN) project, funded by the Open Project For European Radiation Research Area, aimed to develop recommendations for medical and health surveillance of populations affected by previous and future radiation accidents. This paper briefly introduces the points that have been learned from the Fukushima accident from the perspective of SHAMISEN recommendations. [ABSTRACT FROM AUTHOR]

The article reflects on the environmental aspects of Fukushima Daiichi Nuclear Power Plant accident in Japan. Topics discussed include the contemporary feminist discussions regarding the accident, the interpretation of the disaster and the argument by Nobel laureate Elfriede Jelinek, and ecofeminism.

On 11 March 2011, an earthquake of a 9.0 magnitude and the consequent tsunami destroyed Japan’s Fukushima Dai-ichi power plant. Known as 3/11 in Japan, the effects of this triple disaster will continue for decades. How did the media covering the catastrophe articulate issues of risk to the general public? This article is a textual analysis of accounts about the Fukushima disaster published between 11 March 2011 and 11 March 2013 in four of the most prominent media outlets in the United States. In particular, the analysis explores the practices through which these US media constructed the presence and meaning of public health risks resulting from the nuclear meltdown. The article illustrates how systematic media practices minimized the presence of health risks, contributed to misinformation, and exacerbated uncertainties. In the process, the study demonstrates how the media created vernacular epistemologies for understanding and evaluating the health risks posed by nuclear radiation. The article concludes by weighing the implications of the vernacular epistemologies deployed by media. [ABSTRACT FROM AUTHOR]

The residents of Suetsugi in Fukushima Prefecture measured ambient dose rates and radiocaesium concentrations in the soil after the accident at Fukushima Daiichi nuclear power plant in an attempt to maintain living conditions in the region. The measurements were colour plotted into maps to visualise the contamination. Through the receipt of external support, a number of radioactivity-related initiatives were implemented for the residents. Studies were also undertaken regarding the impact of radiocaesium contamination on rice farming in Suetsugi following the Great East Japan Earthquake and the accident at Fukushima Daiichi nuclear power plant.

Iitate, a village in Fukushima Prefecture, suffered little damage from the Great East Japan Earthquake that struck on 11 March 2011. However, all village residents were belatedly ordered to evacuate 1 month after the accident at Fukushima Daiichi nuclear power plant. My family and I had to evacuate to the city of Fukushima, located 40 km from our home in Iitate. This came at a time when my husband and I were planning to start research on Natsuhaze (a type of blueberry grown in Japan) after his retirement. There were conflicting reports. On one hand, the media reported that it was not possible to live in Fukushima. The village of Iitate organised a lecture by an expert to assuage the fear of the residents. The evacuation order 1 month after the disaster contradicted what the expert was saying, and appeared to amplify distrust among the residents. I tried to arrive at my own judgement by measuring the ambient radiation dose in and around my house. Participating in the International Commission on Radiological Protection dialogue seminars provided accurate understanding of the situation. Measurement of radiation doses of wild plants that my husband's father had been cultivating for over 30 years has given me many insights, and I had no concerns about returning to Iitate.

With confirmation of the cold shutdown conditions of the nuclear reactors after the accident at Fukushima Daiichi nuclear power plant, the Japanese Government reclassified the areas under evacuation orders as follows: (1) difficult-to-return zones (>50 mSv y-1), (2) restricted residence zones (20-50 mSv y-1), and (3) zones in preparation for lifting of the evacuation order (<20 mSv y-1). The Government continued its initiatives towards reconstruction of Fukushima, and has lifted evacuation orders in Zones 2 and 3. In terms of radiological protection, the Government emphasised its policy of placing importance on individual dose, and promoted the assignment of consultants in each municipality.

In 2014, a team of high school students and teachers measured individual exposure doses using D-Shuttle dosimeters. In total, 216 students and teachers participated in the project, with the cooperation of 12 high schools in Japan (six from Fukushima Prefecture), four from France, eight from Poland, and two from Belarus. The participants wore the dosimeters for 2 weeks and recorded their locations in diary charts. The distribution of annual exposure doses for each school and region, estimated from the measured results, overlapped. It was concluded that the external exposure of high school students in Fukushima Prefecture was not markedly higher compared with that of students from other regions. [ABSTRACT FROM AUTHOR]

I have learned a great deal by participating in the ICRP dialogue seminars. I will summarise what I have observed and felt regarding the thoughts of the inhabitants of Fukushima over the last four and a half years, and what the ICRP dialogue seminars meant to them. [ABSTRACT FROM AUTHOR]

The accident at Fukushima Daiichi nuclear power plant in the wake of the Great East Japan Earthquake received considerable media coverage. However, a leaning towards sensationalism and a proclivity for denouncing those in power resulted in articles that were, in several instances, scientifically inaccurate, causing anxiety among disaster victims and delaying recovery efforts. Individuals working for the local media in Fukushima had the task of reporting the disaster while being victims of the disaster at the same time. Therefore, many individuals studied and deepened their knowledge about radiation and its effects, and were pained to see inaccurate media coverage of the disaster. Should they have been more forthright in opposing such false media coverage? [ABSTRACT FROM AUTHOR]

'Yes I tried to explain, but residents couldn't understand …' This was the title of my presentation at the first International Commission on Radiological Protection (ICRP) dialogue seminar in November 2011 held at the Fukushima Prefectural Government office. The accident at Fukushima Daiichi nuclear power plant was triggered by the tsunami caused by the Great East Japan Earthquake of March 2011. Initially, it was thought that Date city, 50-60 km away from the accident, would be safe, but unfortunately this was not the case due to the direction of the wind at the time of the accident. I reported on decontamination in the aftermath of the accident at the ICRP dialogue seminar, following an invitation from Dr. Niwa of the University of Kyoto and a member of ICRP. There were many participants from overseas, and it was the first time that I had attended a meeting with simultaneous interpretation. I still remember that I was slightly bewildered.

Between September 2011 and August 2015, the International Commission on Radiological Protection (ICRP) organised a series of 12 stakeholder dialogue workshops with residents of Fukushima Prefecture. Discussions focused on recovery, addressing topics such as protection of children, management of contaminated food, monitoring, and self-help measures. The OECD Nuclear Energy Agency (NEA) supported, and the Committee on Radiation Protection and Public Health (CRPPH) Secretariat attended, all 12 meetings to listen directly to the concerns of affected individuals and draw lessons for CRPPH. To summarise the dialogue results, ICRP organised a final meeting in Date, Japan with the support of NEA and other organisations. The lessons from and utility of the dialogue meetings were praised by dialogue participants and sponsors, and ICRP agreed that some form of dialogue would continue, although with ICRP participation and support rather than leadership. This paper summarises the internationally relevant lessons learned by CRPPH from this important process. [ABSTRACT FROM AUTHOR]

Since November 2011, Institut de radioprotection et de sûreté nucléaire (IRSN) experts have participated in the International Commission on Radiological Protection's (ICRP) dialogue initiative for the rehabilitation of living conditions after the Fukushima accident. In 2013, IRSN and Centre d'étude sur l'Evaluation de la Protection dans le domaine Nucléaire (CEPN) launched a study to identify the main lessons that can be learned from these dialogues, and benefit French IRSN experts in the event of a postaccident situation. The main lesson is that in order to protect the inhabitants of contaminated areas efficiently, experts must work in cooperation with local actors to develop a co-expertise process. The availability of measurement devices for inhabitants is crucial to allow them to assess their own radiological situation. Measuring radioactivity makes it visible, and allows individuals to discuss the results in their communities and develop local projects to improve their daily life. Eventually, inhabitants create a practical radiological protection culture to manage their situation. However, helping people to protect themselves does not mean that authorities and experts have no responsibilities, and this calls for strong ethical principles such as not making decisions for people about their future. To be helpful, scientists need to understand that, as necessary as radiation protection is, it is not the only problem that inhabitants are facing and it cannot control people's lives. Radiation protection experts must commit themselves to be at the service of individuals and the community, and the issues they want to address. [ABSTRACT FROM AUTHOR]

Before the accident at Fukushima Daiichi nuclear power plant in March 2011, I never thought about radiation. After the accident, I originally evacuated with my two sons, but we returned home a few weeks later to be with my husband and parents-in-law as I felt that life with my family was what mattered and the very basis of my happiness. Today, 5 years after the accident, some people are able to think positively about the situation, and some remain uncertain. This article offers my experience and thoughts as a mother to help enable others to feel less stressed about eating food produced in Fukushima, and suggests ideas to help lift their spirits.

This article examines postdisaster public health activities (focusing primarily on parenting support) through collaboration between universities and local government, and reports on the support provided to public health nurses, who are the gatekeepers of community health. For a year after the Fukushima disaster, discussions were held on the short- and long-term measures for responding to the concerns of parents, who face difficulty interpreting risks. Child health checkup data and mothers' counselling sessions with public health nurses were analysed to gather evidence to reinforce the health system over the long term. As the results of the analysis showed a need for the development of a system for communicating health information in ways that are accessible to residents, a health literacy training programme was developed and implemented for public health nurses in Fukushima Prefecture.

The Fukushima nuclear accident raised important questions concerning Japan’s civil society: first, what was the role of civil society prior to the accident; second, what were civil society’s reactions to the accident; third, what impact has civil society had on Japan’s nuclear policies following the accident. Focusing on societal, organizational, and local community-level activities, this article explores these questions analyzing documents and news clippings pertinent to the accident, participant observations of protest activities, and a comparative analysis of Japan’s nuclear policies with Germany’s policy shift. The relative weakness of civil society provided the context for the accident. After the accident, however, energetic citizen protests became frequent. The structures around which protests and public demonstrations were organized changed substantially over time. Civil society has begun to influence public policy, and is fostering a deeper public discourse, while advancing policy proposals. [ABSTRACT FROM PUBLISHER]

The article discusses energy systems and industries in Japan, with a particular focus on the nuclear energy industry. Details on the country's importation of fossil fuels and on safety measures taken within the nuclear energy industry following the March 11, 2011 earthquake, tsunami, and nuclear disaster are presented. Topics discussed include the country's electrical systems, renewable energy sources, and efficiency.

Past opinion polls have shown that major nuclear accidents can have a serious impact on public attitudes. Drawing on a values-beliefs-norms (VBN) model of environmental commitment, the authors hypothesized that a major nuclear accident may also affect the most durable cognitive and cultural foundations that underpin public perceptions of nuclear power. For 32 Italian participants, the authors assessed perceptions of nuclear power and values 1 month before and after the Fukushima nuclear accident. Participants reported decreases in nuclear trust, environmental organization trust, and pronuclear attitudes; they reported a significant increase in environmental beliefs assessed by the new ecological paradigm and a marginally significant increase in altruism. Major nuclear accidents may have the potential to influence values and proenvironmental beliefs, probably for the reason that they are the basis of public attitudes toward nuclear power.

Abstract: A number of dose criteria were set after the accident in Fukushima, including a criterion regarding the use of school playgrounds in Fukushima. Considering the band of 1–20mSv/year recommended by the International Commission on Radiological Protection (ICRP) for public exposure under existing exposure situations, Japanese authorities set 20mSv/year as a ‘start line’ for reducing the dose to school children. However, this led to considerable confusion among the general public and some experts. They thought that the dose limit was increased to 20mSv/year (20 times as high as before), and that school children could be exposed to 20mSv in 1year. This is just an example of confusion caused by inadequate comprehension of radiation effects, misunderstanding of radiation protection concepts, or both. Another issue was raised regarding the higher radiosensitivity of children compared with adults. In the 2007 ICRP Recommendations, a higher risk coefficient is given to the whole population than the adult population, because the whole population includes children; a subpopulation with higher radiosensitivity and a longer life span. The point of argument was whether a lower reference level should be set for children alone. Radiation protection experts should continue to collect scientific information to improve the radiation protection system. In addition, it is the role of these experts to explain the framework of radiation protection to the general public in plain language. [Copyright &y& Elsevier]

Sino-Japanese relationship is too complex a narrative in the study of security and strategic dynamics of East Asia. Despite historical irritants both have developed such a close economic relationship that neither can afford to derail the partnership by any act of miscalculation. Though neither perceives the relationship in zero-sum-game terms, both realize the benefits that would accrue if it is deepened, nothwithstanding the element of fragility in the relationship. More recently, China’s military modernisation and rising assertiveness in territorial issues have raised anxiety in Japan. Similarly, China does not see kindly to Japan’s Defense Guidelines that mentions China as a matter of ‘concern’. The contending claims over the Senkaku Islands are a sore point in the relationship and a solution does not seem to be in the horizon. This article attempts to analyse the intricacies in the bilateral relationship in the context of changing security dynamics in the Asia Pacific region and in the wake of economic interdependence and the desire to foster economic integration of economies. China is a big challenge for Japan. Managing China through regional institutions such as East Asia summit and ADMM Plus are the desirable options. The extended presence of the US as a stabilising force is likely to stay despite talks of US ‘decline’. [ABSTRACT FROM PUBLISHER]

The history of social research can be read as a critical endeavour inasmuch as it unbuttons the normalcy of collective action by multiplying relevant actors and the imaginaries of social reality. I show how paying close sociological attention to what I call cosmopolitical events, offers one approach to such a conception of critical social science. In the paper, I explore the effects of the Japanese events at the Fukushima nuclear plant to unfold its significance as consequences that disrupt, question and alter common and taken for granted modes of ordering social life. Specifically, through approaching Fukushima as a cosmopolitical event we gain insight into the complex processes of normalizing social relations. Moreover, the Fukushima event and its effects demand to extend the history of the sociological imagination to the social and political relevance of the non-human. What emerges is a practice that enriches the process of unfolding research agendas and conceptual space to include those that have been excluded, marginalized, forgotten, unconsidered, or disfigured in the process of normalizing social and political action.
