Abstract

Bu çalışmada, 2x2 inç NaI(Tl) ve LaBr3(Ce) dedektörlerinin foton puls yüksekliği dağılımlarının ve tam enerji tepe verimliliklerinin dedektör ve kaynak arasındaki mesafeye bağlı değişimleri araştırılmıştır. 2 cm ve 5 cm dedektör kaynak mesafeleri ve 30.973, 59.54, 80.998, 302.85, 356.01, 661.65, 1173.24, 1332.5 ve 1408.01 keV gama enerjileri için yapılan hesaplamalar radyasyon taşıma simülasyon kodlarından biri olan FLUKA ile elde edilmiştir. Simüle edilen foton puls yüksekliği dağılımlarındaki Compton sınır değerleri teorik olarak hesaplanan sonuçlarla uyumludur. Ek olarak, tam enerji tepe verimlilik değerleri literatürdeki farklı yöntemlerle karşılaştırıldığında FLUKA simülasyon sonuçlarının tatmin edici olduğu gözlenmiştir.

Abstract

In this study, the variation of photon pulse height distributions and full energy peak efficiencies of 2x2 inch NaI(Tl) and LaBr3(Ce) detectors depending on the distance between the detector and source were investigated. Calculations for 2 cm and 5 cm detector source distances and 30.973, 59.54, 80.998, 302.85, 356.01, 661.65, 1173.24, 1332.5 and 1408.01 keV gamma energies were obtained with FLUKA, one of the radiation transport simulation codes. The Compton edge in simulated photon pulse height distributions is compatible with the theoretically calculated results. In addition, when the full energy peak efficiency values are compared with the different methods in the literature, the FLUKA simulation results are observed are satisfactory.
