GAMMA DOSE VALUES OF STRATIGRAPHIC UNITS OF BEHRAMKALE (ÇANAKKALE) - ZEYTİNLİ (EDREMİT-BALIKESİR) SECTION OF KAZ MOUNTAINS

Abstract

In this study, gamma dose values were measured at 25 locations around a distance of60 km parallel to the Aegean Sea in Güre, Küçükkuyu and Kazdağı regions. These measurementswere made by keeping the Eberline Smart Portable (ESP) scintillator detector constant at a heightof 1 meter above ground level. A SPA-6 plastic scintillation sensor is connected to the instrumenttip to perform the measurement. These devices are direct measurement of external radiation. Asthe measurements were carried out in the open area, 0.2 occupancy factor was used in thecalculations. In the studies, the highest effective dose value was calculated as 0.3 mSv at thelocation 2 (Asos Kadırga Bay). The lowest effective dose value is 0.054 mSV at the 15th location(Avcılar Village Mountain slope) and the average annual gamma dose is 0.14 mSv. For the studyarea, when the lifetime risk of cancer was calculated using gamma effective dose values, it wasdetermined at the highest 2. locations (0.0012) and the lowest at the 15th locations (0,21x10-3).The average lifetime cancer risk value (2,39x10-4) of Turkey, were compared with values calculatedin this study. In this comparison, the gamma dose values of locations 9 and 15 were lower and thevalues of other locations were higher.
