The Safety Requirements publication Preparedness and Response for a Nuclear or Radiological Emergency (IAEA Safety Standards Series No. GSR Part 7) was published in 2015 under the joint sponsorship of 13 international intergovernmental organizations. Requirement 5 of this publication requires governments to ensure that protection strategies are developed, justified and optimized at the preparedness stage for taking protective actions and other response actions effectively in a nuclear or radiological emergency so as to achieve the goals of emergency response. The protection strategy needs to include the decision-aiding means for implementing emergency response actions as well as for justifying and optimizing the strategy. The generic and operational criteria as well as the reference level required to be part of the strategy represent such a decision?aiding means.?The purpose of the workshop is to train personnel of relevant response organizations on how to develop, justify and optimize protection strategy for a nuclear or radiological emergency, as required in Requirement 5 of IAEA Safety Standards Series No. GSR Part 7, and on expected elements of the strategy.The workshop will consist of presentations and working sessions. It will address, in particular, the following topics:
