A model of public evacuation is developed for use in evaluating the efficacy of evacuation as a protective measure in response to atmospheric releases of radioactive material. Differences between this model and the model of public evacu ation previously developed for the Reactor Safety Study p^e described. Based on an analysis of available EPA evacuation data, ranges are suggested for the temporal parameters in the new model. The relative importance of the model paramett.s is also discussed.

The IRPA13 Congress took place from 14-18 May 2012 in Glasgow, Scotland, UK, and was attended by almost 1500 radiological protection professionals. The scientific programme of the Congress was designed to capture a snapshot of the profession's views of the current state of knowledge, and of the challenges seen for the coming years. This paper provides a summary of these results of the Congress in twelve key scientific areas that served as the structural backbone of IRPA13.
