Abstract

3”x3”
NaI(TI) dedektörünün verimliliği ve gama zayıflatma hesaplamaları farklı
kolimasyon parametreleri altında incelenmiştir. Bu amaçla, 511 ve 1332 keV
enerjili foton demetleri, farklı çaplarda Pb kolimatörü kullanılarak kolime
edildi. Bu sistem FLUKA Monte Carlo kodu ile tanımlandı; detektör verimliliği
ve gama zayıflama katsayıları simüle edildi.

Investigation of the Collimator Effect on the 3’’x3’’ NaI(TI) Detector System by the FLUKA code

Abstract

The efficiency of the
3’’x3’’ NaI(TI) detector and gamma attenuation calculations were investigated
under the different collimation parameters. In this purpose, photon beams with
511 and 1332 keV energy were collimated by using Pb collimator with different
diameters. This system was defined by the FLUKA Monte Carlo code; the detector
efficiency and gamma attenuation coefficients were simulated.
