“…Monte Carlo simulations have been used efficiently in radiation protection [ 13 , 14 , 15 , 16 ], materials research [ 17 , 18 , 19 , 20 ], detector design [ 21 , 22 , 23 ], and medical applications [ 24 ]. In this work, two different 2 × 2 inch NaI(Tl) and LaBr3(Ce) scintillation detectors were modeled in terms of their full energy peak efficiency measurements and comparisons.…”
