This study conducted a comparative analysis of dose evaluations for ingestion of animalproducts based on data from nuclear power plants in the Republic of Korea, using methodologies fromthe Republic of Korea, ‘IAEA TRS-472’, and ‘CSA N288.1:14’. The research focused on tritium, the mostsignificant constituent among the gaseous and liquid radioactive emissions. The combined evaluation oftritium, in the form of tritiated water (HTO) and organically bound tritium (OBT), yielded results of 1.143μSv y-1 for the Republic of Korea, 0.965 μSv y-1 for ‘TRS-472’, and 0.886 μSv y-1 for ‘N288.1:14’. Despite theRepublic of Korea’s guidelines not considering OBT, the evaluation results for the Republic of Korea werehigher compared to other methodologies. This discrepancy was attributed to the unique approach of notconsidering the moisture content per individual in the calculations of plant and feed concentration in theRepublic of Korea and the simultaneous consideration of specific-activity model and transfer model. Thestudy highlights the necessity of developing dose evaluation models tailored to regional characteristicsand underscores the importance of including OBT in these evaluations.
