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/m³ 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.
