Consequence analysis with probabilistic approaches. Final report on WP 3.1

The COSYMA system used in the TSK 2009 is to be replaced by the model ARTM and the subsequent dose modelling with the GRS-SBG dose module. For this purpose, com-parative calculations with COSYMA were performed and discussed against the back-ground of deviating input and model parameters. In view of the major changes in the models for dispersion and dose calculations and in the parameters, the deviations were rather moderate. With these comparative calculations from the ARTM model and the subsequent dose modelling with the GRS-SBG dose module with the previous calcula-tions with the GRS version of the LASAT${}^{\circledR }$ model and the dose calculation with COSYMA, a change in the model landscape is now possible in the case of transport risk analysis.
