Return on experience of the post-accidental management of the Chernobyl accident within the Belarusian context - PAREX. Synthesis report delivered to the ASN on the 19 March 2007

This approach to a return on experience of the post-accidental management of the Chernobyl accident identified four main steps: the passage from an accidental phase to a post-accidental phase from 1986 to 1991 (implementation of countermeasures, design of a radiological protection), the setting of an institutional and legal framework for the post-accidental management from 1991 to 1993 (compensations, definition of standards for food production and consumption, psychological support of populations), the search for alternative strategies from 1993 to 2001, and a sustainable rehabilitation of living conditions in contaminated territories between 2001 and 2006. Based on the return on experience on this various issues, the authors draw a set of lessons and give recommendations. They notably address the characteristics of a situation of durable radiological contamination, the role of standards in the response to a post-accidental situation, the role of expertise and knowledge building, the role and action of public authorities, the progressive building up of a local response to the crisis, the preparedness to a situation of durable contamination
