Abstract :"The monitoring of the radiological effects of nuclear power plants around Turkey” was added to TAEK's annual work programme as an ongoing activity for the purpose of monitoring the radiological effects of nuclear power plants around Turkey in 2013. As part of this activity, The Iğdır Region Environmental Radiological Monitoring Program was completed in 2015 (TAEK, 2015) and radiological monitoring studies were carried out within this program (TAEK, 2017). Air, surface water, soil, drinking water and local food samples were collected and laboratory measurements were performed for the determination of environmental radioactivity levels. Periodic dosimetric evaluations were done using environmental dosimeters and the continuously operated RESA (Early Warning Environmental Radiation Monitoring System) units stationed in the region. Standard methods and quality control systems, of ÇNAEM and SANAEM, particular to analyzes, were used for sampling and analysis. During 2013-2016 period, following results are detected as the maximum values for · I-131, milk samples <50.0 Bq/ kg, · Cs-134, beet samples<0.7 Bq/kg, · Cs-137, soil samples=25.3 ± 3.8 Bq/kg, · Sr-90, soil samples=12.69 ± 0.13 Bq/kg Detected radioactivity levels in drinking water samples are below the monitoring levels (Official Gazette, 2013). Maximum H-3 activity was detected as 0.82 Bq/m 3 and total indicative dose, for the measured Sr-90 and Cs-137 values, was calculated as 87.89 nSv/year considering the ingestion of drinking waters. These values are rather below the limit value of 100 Bq/l for H-3 and 0.1 mSv/year for total indicative dose, meaning the activity of H-3 and other dose contributing nuclides in the drinking waters are not needed to be further monitored. In conclusion, no unusual founding is found.Keywords : Environmental dosimetry, Environmental radioactivity, Armenia, Ionizing Radiation Measurement and Monitoring, Metsamor NPP, Nuclear Facilities, Radiation Dose Calculations, Radiation Protection, Radiation Measurement Systems
