When the BIOMOVS study started in 1985 a scenario (B1) for the transfer of I 131 via the air-pasture-cow-milk pathway was defined for model inter-comparison, as this is one of the most important pathways for radionuclide releases from nuclear power plants and probably the best investigated radioecological problem. The predictions for milk (except from the model PATHWAY) were all within a factor of 20 and generally the modelers were satisfied with their results, as all differences in the predictions could be explained by the individual assumptions or the model intentions, i.e. conservative results or best estimates.The comprehensive measurements of I 131 in the environment after the Chernobyl accident gave a unique opportunity to receive new and independent datasets for model validation. Since then the necessary site specific data have been assembled for 13 different locations that cover a large range of I 131 air contaminations, and have been offered to participants for calculation (scenario A4). The results will be discussed at the next BIOMOVS workshop in December 1987 in the USA, but the outlines of the study are presented.
