Session 136 - Roundtable: IAEA Modaria II Report on Risk Informed Decision Analysis Stakeholder-engaged through Case Studies of Legacy and NSRM Site

This roundtable discussed the recently completed work of Working Group 1 of the IAEA Programme on Modelling and Data for Radiological Impact Assessments (MODARIA II). It deals with a framework for integrating radiological risk assessment and decision analysis for legacy and NORM sites. A specific focus of this integration is on providing awareness of the needs and expectations regarding risk assessment results in the larger decision context. This framework is demonstrated by three case studies for which existing exposure situations needing remediation have used or could use this approach to support risk-informed decision-making, a key component of any program for the management, remediation and D and D of nuclear legacy and NORM sites.
