In 2003 IAEA launched the EMRAS Programme aiming at evaluating the predictive power of radiological models. The Iodine Working Group reassessed the impact of the release of I during the Chernobyl accident with the aim of comparing model predictions with environmental data and inter-comparing the model predictions. As for the Prague Scenario, milk supply regions of three big dairies were chosen for the model validation. The most important peculiarities of Prague Scenario were keeping milk cattle in sheds and a special feeding regime during May 1986. The modelers were asked to assess the I content in the thyroid of the local population and the resulting dose. The assessments were compared with measurement data. The results of these model calculations and their comparison with experimental data are presented.
