Bu
çalışmada Geant4
tabanlı GATE simulasyon programı kullanılarak NaI(Tl) detektörünün
toplam verimi hesaplandı. Simulasyon, 50-3000 keV foton enerji
aralığında çeşitli kaynak-detektör uzaklıklarında izotropik
nokta ve disk gama ışını kaynağı kullanılarak
gerçekleştirildi. Sonuçlar, 1958-2018 periyodu boyunca elde edilen
farklı analitik ve Monte Carlo hesaplamaları sonuçları ile
karşılaştırıldı. Hesaplanan ve GATE simulasyonuyla elde edilen
sonuçlar birbiriyle uyumlu çıkmasının yanında düşük
enerjideki gamalar için çok daha hassas sonuçlar bu çalışmada
bulunmuştur.
