Database for Radionuclide Transport in the Biosphere:Nuclide Specific and Geographic Data for Northern Switzerland
The biosphere model is the final link in the chain of radionuclide transport models, used for radiation dose calculations from high-level waste repositories. This report presents the data needed for biosphere calculations and discusses them where necessary.
The first part is dedicated to the nuclide specific parameters like distribution coefficients (water – soil), concentration ratios (soil – plant) and distribution factors (for milk, meat etc.) which are reported in the literature.
The second part contains the choice of regions, their division into compartments and the discussion of nutritional habits for man and animals.
At the end a theoretical human population for each region is estimated based on the consumption rates and on the yield of agricultural products, assuming an autonomous nutrition.
