6th SETAC World Congress 2012
2011-12-26 - Environmental radioactivity

[ 20-24 May 2012 - Berlin, Germany ]

The Society of Environmental Toxicology And Chemistry (SETAC) organizes this 6th edition on the theme Securing a sustainable future: Integrating science, policy and people.

SETAC’s focus will be on integrating different views and disciplines, on balancing the conflicting interests of stakeholders and on addressing societal needs of the future. The goal is to develop a sustainability management framework with tools that have a positive impact on the global environment.

Special session 09: Radionuclides and Radiation

Wednesday 23 May 2012 - 8:00-12:45

Chair/co-chair: François Bréchignac, IRSN-IUR (France) and Igor Linkov, ERDC-EL-MS (USA).

In the wake of the compound March 2011 nuclear disaster at the Fukushima nuclear power plant in Japan, international public dialogue has repeatedly turned to questions of the adequacy of existing regulatory frameworks to protect us from nuclear harm. It is clear that the sustainability of using nuclear energy and radioactivity for civilian purposes needs to be grounded to societal acceptance. Societal acceptance in turn is highly dependent on the transparent explanation of risks and the demonstration that continuous effort is dedicated to close uncertainties with appropriate knowledge and understanding. Emerging lessons seem to indicate an opportunity to enhance resilience through systemic levels of risk aggregation. This session will discuss frameworks for bringing systemic reasoning to the risk management process with focus on radioecology.
