This paper proposes a methodology supporting decisions on protectivemeasures following severe nuclear accidents and demonstrates its use. A multicriteria decision analysis approach is adopted where value tradeoffs are postponed until the very last stage of the decision proces. All feasible solutions are implicitly considered and evaluated inthe chosen criteria. Technically inferior solutions are excluded. Only the non- dominated or efficient solutions forming the 'efficient frontier' are retained and presented to the decision makers. Implementation of inefficient solutions is in this way avoided. A choice amongthe efficient solutions, although it implies value tradeoffs among the multiple ciiteria, avoids the direct and a priori assessment of preferences. An interactive computer package has been developed with which the decisionmaker can choose a point on the efficient frontier inthe consequence space and immediately see the corresponding alternative in the decision space. The methodology is demonstrated through anapplication on the choice among possible protective measures in contaminated areas of the former USSR after the Chernobyl accident using as criteria the collective effective life-time dose received by the population and the cost associated with each possible decision.
