1. Advantages and disadvantages of simple models Moderator’s introduction D. Galeriu, IFIN-HH Romania

2. UFOTRI cow, tested favorably Transfer from Grass OBT to Milk OBT mimics De nuovo synthesis Improve biokinetic loss Can be expanded to Sheep and goat, using Results from MAGENTC

3. Keum et al., Health Physics, January 2006, Volume 90, p.42 • - Compartmental, parameters are established from mass balance of H and average conditions; • - Loss rate from leaf to air is taken from initial Belot’s approach; • Limitation: for acute emissions can not cope with event specific conditions • no transfer leaf OBT> grain OBT

4. suggestion • Consider a compartmental model for late phase, with site adapted parameters • Initialization from a more advanced model for initial phase • Distinguish continuous harvested plants and perennial
