Présentation

This book, dedicated to the implementation of inclusive risk management processes involving citizens and experts in the post-nuclear accident reconstruction phase, is the result of extensive experience gained by researchers and practitioners in the areas contaminated by the Chernobyl accident in Belarus, Norway and the United Kingdom, and the Fukushima accident in Japan. Coming from diverse backgrounds, they enthusiastically shared their experiences, while adhering to rigorous scientific standards, to write thirteen essays that shed light on the challenges of restoring living conditions after a major nuclear event.
Building on the recommendations of the International Commission on Radiological Protection, a series of analyses and testimonies are offered to students and researchers, as well as to professionals in the social sciences and humanities committed to risk governance and cooperation with public and private sector stakeholders.

“In a time when expertise alone no longer guarantees legitimacy, this book shows how co-expertise ― sustained dialogue and shared responsibility ― can reshape post-accident recovery. A thoughtful and timely contribution to the future of risk governance”. Christopher Clement, ICRP Scientific Secretary and IRPA President

“The co-expertise process offers profound insights and courage to all those who live in a risky society. It is a ‘technology of humility’ for safeguarding human values and for jointly building the future”. Toshimitsu Homma, co-author of ICRP Publication 146

“Scientific rigor is essential in the co-expertise process, but it is the respect for human dignity that really makes a difference. Each chapter stands as a testament to this simple truth”. Nobuhiko Ban, former Commissioner NRA Japan
