Multiple model testing using Chernobyl fallout data of I-131 in forage and milk and Cs-137 in forage, milk, beef and grain. Pt. 2

BIOMOVS is an international study for testing and validating model predictions of the transfer of radionuclides and rare stable elements through the biosphere. The BIOMOVS A4 scenario was designed to test model prediction of the transfer of I-131 and Cs-137 from the atmosphere via pasture vegetation to milk and of the Cs-137 transfer from air to beef (via vegetation) and grain. This document is an appendix to the A4 report. It includes tables and figures of time-integrated results, a summary of a statistical analysis of time-dependent and representative figures of time-dependent results. The quantities to be predicted in this scenario were wet, dry and total deposition (Bq m-2) of I-131 and Cs-137, contamination of vegetation (Bq kg -1 d.w.), milk (Bq L-1), beef and grain (Bq kg-1). While with steady state models only time-integrated results for vegetation, milk and beef could be calculated, these quantities also were requested as time-series from users of dynamic models. A detailed description of the participating models is given in Appendix 3, while all collected observations are documented in Appendix 2 of the A4 report. A diskette with all observed data can be obtained from the Swedish National Institute of Radiation Protection, SSI, or from Harry Koehler, IAEA, Vienna, Austria. For time-integrated P/Os, graphs for all locations and all models and sometimes subsets of these are provided. For time-series, graphs are enclosed for the observations and some model results. These values are calculated across locations and across models for time-integrated predictions and for the P/O of entire time-series and subsets of these for the time-dependent predictions. (au)
