Abstract

A methodology for evaluating and ranking restoration strategies for radioactively contaminated sites has been elaborated in a project (RESTRAT) under the Fourth Framework of the Nuclear Fission Safety Programme of the EU. The decision-aiding tool developed in this project was based on the principles of justification and optimisation of radiation protection. A multi-attribute utility (MAU) type of analysis was applied in order to be able to deal with social factors, next to radiological health and economic cost attributes. Potentially relevant restoration techniques were identified and their characteristics determined through a literature review. The decision-aiding tool developed has been illustrated by application to representative examples of different categories of contaminated sites. In this paper the results for a contaminated freshwater riverine site are shown.
