    Assessment of Gama Dose Rates around Gaziantep City, Turkey
    (Ankara : Ankara Üniversitesi, 2017) Zuhur, S.; Çeliktürk, D.; Yazıcı, A. N.; Öztürk, Z.; Fen Fakültesi
    In this study, the measurements were performed 1 m above the ground in air and surface soils at certain points in the city of Gaziantep located at south of Turkey with a populatıon of 1.5 million. Air and soil measurements were carried out by portable detectors and gamma spectrometry system. As a result of measurements performed in the air, average annual effective dose of 66.81 µSv y-1 and gamma counting of 50.43 1 s-1 were found. On the other hand, as a result of gamma spectrometric analyses in the surface soil samples, average activity concentrations of 226Ra, 232Th and 40K were found to be 28.92, 29.49 and 255.30 Bq kg-1, respectively. Calculated absorbed dose rate and annual effective dose values depending on the activity concentrations, were found to be 38.45 nGy h-1 and 47.17 µSv y-1. When the measured values are compared with UNSCEAR 2000 report’s worldwide average value, our result is slightly lower than these values.
