Over 200 cases of juvenile thyroid cancer have been found in Fukushima since 2011. This phenomenon is now regarded to be caused by overdiagnosis of self-limiting thyroid cancer which exists at high prevalence in the young. The overdiagnosis was caused by the thyroid screening with ultrasonography (US), which also caused overdiagnosis in Korea. For many reasons, the thyroid screening program in Fukushima is still ongoing without any changes. The majority of residents in Fukushima still request to continue the program since they are not informed about the harms of this program. Since the US examination is performed as one of the school program, the rate of participation by schoolchildren is over 90%, which has resulted in expansion of the disaster. The Fukushima thyroid cancer disaster provides us a valuable opportunity to reconsider about medical ethics.

This paper discusses a general framework for examining the structure and the function of scientific literacy, which is an important element of risk literacy. There are five layers of literacy: (1) basic literacy for communication in documents; (2) functional literacy in everyday life and the workplace; (3) scientific and mathematical literacy, and media and Internet literacy for students and citizens; (4) civil literacy for citizenship; and (5) academic and research literacies for professionals and researchers. This paper focuses on the concept of scientific literacy as informed by Baltes’s five criteria of wisdom (Baltes & Smith, 2008): factual knowledge, procedural knowledge, contextualization, value-goal relativism, and recognition and management of uncertainty. In addition, scientific, media, and mathematical literacies are basic elements of risk literacy, as civil literacy is for citizenship. Risk-literate citizens can understand risk information and manage their risk. Four methods for improving the scientific and risk literacies of the public are discussed: science education, science communication by mass media, and practices of local and Internet communities.

According to our study of “Public Risk Cognition of Pandemic Flu and Risk Communication” conducted in November 2008, we found that it's extremely important to understand how people recognize Pandemic Flu(H5N1 type) and which way of risk communication is required. As novel H1N1 flu(Swine flu) virus caused outbreaks in April 2009, it was proven that Japanese government's risk and crisis management response and risk communication strategy didn't work well. Fortunately H1N1 flu virus was as severe as seasonal influenza. However, learning from this time's H1N1 pandemic, we've found it urgent to consolidate Japanese government's risk communication strategy for the event of a second wave of H1N1 and prospective outbreaks of highly-virulent H5N1. Our study should give much valuable suggestions to planning of the strategy.

In this paper, I considered the novel coronavirus pandemic as general as possible from the aspects of emerging risks and the relationship between science and policy. For the former, it was proposed to institutionalize mechanisms such as national risk assessments carried out in other countries, and for the latter, to visualize the process from scientific facts to the determination of risk management measures. In addition, responding to the novel coronavirus requires the involvement of experts not only from a medical point of view, but also from a behavioral point of view.

This paper will make an overview on current radiation risk assessment and management, and also discuss current issues after reflection of the accident at the Fukushima Daiichi nuclear power station in 2011. Historically, the risk-based approach was introduced based on the assumption that radiation risk follows a linear-non-threshold model for cancer and hereditary effects. Since then, radiological protection has developed the principles and the fundamental framework for the risk management. Currently, radiological protection has evolved from a “classical” top-down approach. The talk and collaboration between radiological protection community and risk analysis community like SRA will be needed to build more acceptable and feasible management and regulation for radiation and chemicals.

A panel discussion with media was conducted in the 29th annual meeting of SRA Japan. The panel discussed how to collaborate between media and experts on risk issues. The background of the panel discussion is as follows: Modern society is confronted with diverse risks. The role of media is to report news timely and clearly. Psychological and ethical aspects are closely related with risk although the risk is quantitative for uncertain information. The uncertain aspects with diverse views on risk issues have blocked the difficulties of media reports to help people act properly to face the risk. In order to solve the problems, we should continue to think how to collaborate between media and experts.

It is important to infer and respect others' values and attitudes for fruitful communication. This paper examines how experts and lay people infer others' risk perception. According to the 2009 questionnaire survey for academic professionals and the general public, professionals estimate that there is a larger difference in risk perception of the technology that they study between themselves and lay people than the general public does. The professionals who hold this feeling perceive the risk of technology as being lower and estimate lay people' s risk perception to be higher. They also focus on positive more than negative aspects of the technology, evaluate its benefits, and tend to presume that negative media coverage greatly affects public perception.

For examining the remaining reduction of demand and price slump in some farm and marine products of Fukushima prefecture after 7 years of the nuclear disaster, it is necessary to articulate the interrelated three aspects of (risk) judgements made by the market, society, and individuals. After clarifying the aspect of the market where the efficacy of scientific risk judgement is limited, this study will discuss the relationship between social and individual risk tradeoff concerning food from Fukushima, and point out the importance of socially respect for self-determination in reference to the Norwegian case.

Before the Fukushima Daiichi nuclear power plant accident, radionuclide like 137Cs released from atmospheric nuclear detonation tests and the Chernobyl accident has been transported worldwide in the environment and finally taken up by humans through various pathways. In this research, dietary intake of 137Cs and the health risks caused by prolonged radioactive global environment contamination were evaluated age-dependently for the reference Japanese since 1945 until 2010 by using the mathematical model for the evaluation of global distribution of 137Cs with food ingestion and domestic and international food supply model. The model estimates were compared with the monitoring data of 137Cs in Japanese total diet and 137Cs concentration in food as an attempt at validation. The results of this evaluation would be useful for understanding the background situations without the Fukushima accident and give important information for the radiological health risk assessment of the accident.

Risk assessment of technologies and social activities involves subjective judgment as one of its components, which depends on the perception of risk by individuals. In the present study, we undertook a survey of public perceptions regarding the social issues and risks, the images of radiation, and acceptance of its application and health risk.The majority identified global warming as highly risky among social issues related to technology, and smoking among health-damaging issues, but not radiation-related items such as natural radiation, artificial radiation, and X-ray/CT examinations. In general, a sexual distinction was observed regarding perceptions of sick house and food safety. Forty percent of the public inaccurately believed that the main source of daily exposure was nuclear facilities. Many citizens associated the word of radiation with medical exposure, death/damage/disease and nuclear weapon including A.bomb, and connected the health effects of radiation with cancer and leukemia. However, majority did not bring up any image from the terms of “radiation” and “health effects of radiation”

In the 1990s, the so-called ‘sick house syndrome’ became an area of public concern. Consequently, the Ministry of Health, Labour and Welfare of Japan established Indoor Air Guidelines for 13 compounds as a preventive measure against sick house syndrome. In recent years, lower concentrations of the 13 chemicals in newly built houses diminished the health risk from those chemicals. As a result, instead of the regulated chemicals, unregulated chemicals such as methylcyclohexane, dichloromethane and acetone became common in building materials. These chemicals have also been found to cause sick house syndrome. Thus, in addition to the regulation of individual chemicals, it is now believed that it is necessary to minimize the total amount of volatile organic compounds (VOCs) in order to diminish the health risk from indoor air chemicals.

The forms of risk communication in Japan changed drastically after the Hanshin-Awaji Earthquake. While the pre-Earthquake risk related information was based on the myth of zero-risk, the post-Earthquake risk communication has required a much higher level of fair and open information, which is now the main current of this field. At the same time, other theoretical and practical problems have recently been founded. Those problems include (1)the philosophy and value system underlying risk communication, (2)the causal relation between risk communication and credibility, (3)whether the citizen really want risk information or not, (4) whether citizen's risk perception is emotional or not, (5)the organizational climate as a factor in successful risk communication, (6)misunderstanding of the meaning of precautionary principle, (7)the skill of the risk communicator, (8)the importance of wording and logic in risk communication, (9)how to construct good relations between risk agent and mass media , etc. The purpose of this paper is to integrate the notion of risk communication with the macro view in both time and space, which used to be based on the idea of a one-shot and local solution to future disasters.

We have identified the cause of the formaldehyde pollution that occurred in the Tonegawa River system in May, 2012. We analyzed 10 river water samples that were collected in the Edogawa River using a liquid chromatography/ tandem mass spectrometry (LC/MS/MS) and a liquid chromatography/ ion-trap time-offlight mass spectrometry (LC/IT-TOF-MS). As a result, hexamethylenetetramine was detected in all the water samples. Further, significant relationship was observed between the hexamethylenetetramine and the formaldehyde concentration in the same sample (r2=0.9576). Furthermore, formaldehyde concentration calculated by the reaction formula was very similar to the measured formaldehyde concentration in each sample. Therefore, we concluded that the cause of the formaldehyde pollution was the inflow of hexamethylenetetramines in the river system. Further, we focus the future issues on the management of unregulated chemicals in drinking water.

For complete revival of the East Japan great earthquake, withdrawal of waste and sludge, disassemble of collapse buildings, etc. are performed over a long period of time. In these cases, many particulate matters included asbestos are generated, and will induce lung cancer or mesothelioma in tens of years. Since the health risk following exposure to the present environmental concentration of asbestos is about 10-5, we should control the scattering of asbestos into environment and prevent the inhalation by wearing an anti-dust mask (national assay disposable mask DS2, N95) .
