Prognosis calculations and measurements of contamination: steps in the assessment of radiation exposure via the ingestion pathway in the case of an accident

The possibilities for the making of prognoses and the carrying out of measu rements for the assessment of radiation exposure via the ingestion pathway are presented together with decision-making possibilities for the implement ation of measures in the areas of agriculture, and the production and distr ibution of food-stuffs Further to this the modelling of radionuclide transf er for relevant processes within the ingestion pathway, and their influence on the uncertainty values for the model calculations are discussed. The de gree of conclusiveness of the data in terms of their variability and repres entativeness is discussed, along with the degree to which they can be used in the adaption of the prognosis calculations. The implications of interreg ional and cross-border goods traffic are defined. The possibilities for a m utually agreed upon procedure for the optimized implementation of the diffe rent programmes in respect of the evaluation of a radiological situation un der circumstances in which only limited resources are available is presente d.
