Abstract (2. Language): 
In present study, water phantom performances of using 6 and 18 MV photon beams were investigated. For this purpose, several data obtained form percent depth dose graphics and dose profiles were compared to each other. It was determined that the differences between the values were generally found within the limits. In the end of study, it was seen that semiconductor diodes and cylindrical ion chambers can be used interchangeably. But, there are some dozimetric differences between both detectors because of different detector structures. Choice of the detector can be made by taking into account these differences.

Abstract (Original Language): 
Bu çalışmada; 6 ve 18 MV foton ışınları kullanılarak yarı iletken diyotlar ve silindirik iyon odalarının su fantomunu performansları incelenmiştir. Bu amaçla, yüzde derin doz ve doz profillerinden elde edilen çeşitli veriler bir birleri ile karşılaştırıldı. Değerler arasındaki farklar genel olarak limitler içinde tespit edilmiştir. Çalışmanın sonucunda diyot ve iyon odası tipindeki detektörlerin her ikisinin de su fantomu ile yapılan rutin ölçümlerde kullanılabileceği görülmüştür. Fakat detektör yapılarının tamamen farklı oluşu sebebiyle aralarında bazı dozimetrik farklar mevcuttur. Bu farklar gözetilerek detektör kullanımları arasında tercih yapılabilir.
