Korean Ingestion Dose Assessment Model for Level 3 PSA

This paper describes a food ingestion dose assessment model (K-PUBDOSE), which has been developed based on the farming characteristics of Korea for a Level 3 PSA. The model consists of three sub-modules: agricultural plant contamination assessment model, animal product contamination assessment model, and ingestion dose assessment model. The model considers eight human foodstuffs (grain, vegetables, fruit, milk, beef, chicken, egg, and pork), and three livestock feedstuffs (rice-straw, pasture, and corn) in order to ensure consistency with the existing domestic regulatory system. The performance of the model has been tested through the calculation of the activity concentration of Cs for crops and animal products, and subsequently, the ingestion dose for five age groups for unit deposition. The calculated results represented well the contamination characteristics of crop and ingestion dose according to the deposition date. In conclusion, the model is expected to be effectively used as an ingestion dose assessment model for the Korean Level 3 PSA, which is currently being developed.
