In this study, radiological impacts of atmospheric releases and aquatic discharges due to the routine (normal) operation of Metsamor (Armenia) Nuclear Power Plant (NPP) on the public living in Province of Iğdır (Turkey) were investigated by two approaches, (1) using PC CREAM 08 software and (2) using the method provided in the IAEA SRS 19 safety report (International Atomic Energy Agency). Based on the obtained results, estimated public doses in the region by both approaches comply with 0.1 mSv/year dose constraint (NDK, 2019). The results showed that the main exposure pathways for the public based on maximum public doses in PC CREAM 08 approach are food consumption, external gamma and fish consumption due to atmospheric releases and aquatic discharges whereas food consumption and fish consumption are the main exposure pathways for IAEA SRS 19 approach. In PC CREAM 08 approach, the main dose contributing radionuclides were obtained as 14C, 41Ar, 3H, 131I and 137Cs for atmospheric releases, and 137Cs, 134Cs and 3H for aquatic discharges. On the other hand, the main dose contributing radionuclides were obtained as 137Cs, 134Cs, 90Sr and 131I for atmospheric releases, and 137Cs, 134Cs and 90Sr for aquatic discharges for IAEA SRS 19 approach. As a conclusion, the health risk on the public living in Province of Iğdır due to routine operation of Metsamor NPP was determined as so small (the probability of total cancer risk for an individual is 7.67E-08 in PC CREAM approach and 5.40E-07 in IAEA SRS 19 approach).
