Large nuclear accidents, like Chernobyl and Fukushima, introduce great complexity into society. The technical response mobilizes authorities and experts who are faced with many challenges to effectively control the risk of radiation during the emergency response and the recovery phase. This mobilization is largely based on past experience with nuclear disasters and appeals to all the scientific knowledge of radiation effects on humans and the environment. As far as the affected society is concerned, and particularly the people living in the contaminated areas, the accident results in the sudden outburst of the complexity of the environment in which individuals are used to evolve which is raising a lot of questions and concerns particularly concerning the risk of radiation to health. The irruption of radioactivity into everyday life also seriously affects the well being of directly affected people and the quality of the 'living together'. In such a context the objective is not only the protection of people against the potential health consequences of radiation, but also the maintenance of sustainable living conditions including respectable lifestyles and livelihoods.
The Chernobyl and Fukushima experience has shown that in order to overcome the numerous difficulties associated with the presence of radioactivity in the daily environment, it was essential to directly involve in the management of the situation the people who make the choice to remain in the affected territories. This implies for the authorities, experts and professionals, especially health professionals, to intervene on the ground to develop innovative social processes aiming at protecting people and restoring control on their daily life. Needless to mention that in such a complex context, the communication of authorities and experts is a major challenge in the management of the situation, but also a very difficult exercise given the widespread distrust among the public.
How to apply effectively the scientific knowledge, ethical values and principles of radiological protection to nuclear emergencies and post-accident situations?
How to involve affected stakeholders in their protection and the rehabilitation of their living conditions after a nuclear accident?
How to communicate about radiation risk in nuclear emergency and post- accident situations?
These are the questions to which the Department of Health Risk Control tries to provide elements of response taking into account the analysis of past and present experiences in intervention with public authorities and working with the population in areas affected by radioactivity. To support its approach, the Department adopts a trans-disciplinary approach combining the scientific bases of radiological protection with environmental and social sciences.
