Feedback experiences from Fukushima and Chernobyl situations have clearly shown the importance of involving local stakeholders living in contaminated territories for the rehabilitation of their daily life. In this context, this paper aims to better address the role of radiological protection experts in the recovery phase of post-nuclear accident situation, in mainly relying on the analysis of local initiatives implemented in the Fukushima Prefecture following March 2011. In the first part, this paper highlights the various challenges faced by the population living in contaminated territories, i.e., rehabilitation of the living conditions, ensuring a long-term radiological monitoring, developing public health programs. In a second part, this paper discusses to which extent radiological protection experts can help local population to address these challenges, particularly through the implementation of co-expertise processes and the associated ethical issues and values they should embody. The last part of this paper particularly focuses on two current challenges at stake in the Fukushima Prefecture: the dissemination of the co-expertise process to all affected communities, as well as the sustainability of these approaches over time.
A case study was conducted in the village of Komarin in Belarus at the edge of the Chernobyl exclusion zone, with the aim of evaluating the spatial and temporal variability in external and internal post-accidental radiation exposure. A database containing the radioactive measurements of foodstuffs made in Komarin over a 1990–2016 period makes it possible to estimate retrospectively the internal exposure. External exposure was prospectively studied through a citizen science approach involving a group of high school students and used two radioactive monitoring approaches, the D-shuttle© dosimeter and the OpenRadiation® system. Results showed that contamination level in food products varied over 2 to 4 orders of magnitude, underlining the usefulness of continuous monitoring of locally produced foodstuffs even more than 30 years after the Chernobyl accident. The study of external exposures showed that the current dose rates were similar to those usually observed elsewhere in the world, without any notable variations. More detailed analysis of these results will be conducted in future studies. This paper focuses on the methods used for the acquisition of data about both external exposure and foodstuff contamination and how it resulted in the strong involvement of high school students which in turn triggered a renewed interest in the practical radiological protection culture within the population of the village.
The paper aims to stimulate reflection and debate on the issue of uncertainty as a key component of nuclear or radiological emergency management. It identifies and discusses different types of uncertainties that appeared during and after real emergencies. For this, seven different case studies of nuclear and radiological events have been analysed using three separate methodological approaches: i) case descriptions (document review); ii) media analysis; and iii) semi-structured interviews. The overall objective was to elucidate the understanding and response to scientific and social uncertainties, and related ethical issues. A range of different uncertainties were identified and roughly grouped into categories related to: 1) technical and measurement uncertainties; 2) societal impacts and societal framing; 3) contradictory information and communication aspects; 4) ethical aspects. This analysis intends to inform emergency managers on the types of uncertainties that may appear to different actors during nuclear or radiological emergency. The results should serve to stimulate preparation on the uncertainty response and by this also to reduce some of the identified uncertainties.
Under the framework of the CONFIDENCE project, work package 4 was focusing on the transition to long-term recovery, involving stakeholders in decision-making processes. The essential research was performed using a participatory approach, which combined scenario-based stakeholder discussion panels and transnational stakeholder surveys following the Delphi methodology. The objective was to identify and address the issues and uncertainties arising in the preparedness and management of the transition phase and to explore ways to facilitate the incorporation of stakeholders’ expertise, points of view and interests in the decision-making processes. The final goal was to build best practices for planning optimal remediation strategies during the transition phase considering stakeholder involvement in the decision-making process. The results obtained from the work undertaken in nine European countries are presented.
NERIS is the European platform on preparedness for nuclear and radiological emergency response and recovery. Created in 2010 with 57 organisations from 28 different countries, the objectives of the platform are to: improve the effectiveness and coherency of current approaches to preparedness; identify further development needs; improve 'know how' and technical expertise; and establish a forum for dialogue and methodological development. The NERIS Strategic Research Agenda is now structured with three main challenges: (i) radiological impact assessments during all phases of nuclear and radiological events; (ii) countermeasures and countermeasure strategies in emergency and recovery, decision support, and disaster informatics; and (iii) setting up a multi-faceted framework for preparedness for emergency response and recovery. The Fukushima accident has highlighted some key issues for further consideration in NERIS research activities, including: the importance of transparency of decision-making processes at local, regional, and national levels; the key role of access to environmental monitoring; the importance of dealing with uncertainties in assessment and management of the different phases of the accident; the use of modern social media in the exchange of information; the role of stakeholder involvement processes in both emergency and recovery situations; considerations of societal, ethical, and economic aspects; and the reinforcement of education and training for various actors. This paper emphasises the main issues at stake for NERIS for post-accident management.
