In this study, gamma dose values were measured in the study area around a distance of 60 kmparallel to the Aegean Sea in Güre, Küçükkuyu and Kazdağı regions. In the study, gamma dose values were measured at 25 locations that best represent the area. These measurements were made by keeping the portable Eberline Smart Portable (ESP) scintillator detector constant at a height of 1 meter above ground level. A SPA-6 plastic scintillation sensor isconnected to the instrument tip to perform the measurement. These devices are direct measurement of external radiation. As the measurements were carried out in the open area,0.2 occupancy factor was used in the calculations. In the studies, the highest effective dose value was calculated as 0.3 mSv at the location 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 study area, when the lifetime risk of cancer was calculated using gamma effective dose values, it was determined at the highest 2 locations (1,2x10-3) and the lowest at the 15locations (0,21x10-3). The average lifetime cancer risk value (2,39x10 -4 ) of Turkey, were compared with values calculated in this study. In this comparison, the values of locations 9 and 15 were lower and the values of other locations were higher.
