This study aimed to simulate the gamma-ray energy spectrum of Ga-67 with the Monte Carlo methods. The simulation was conducted one million photons as the samples. The probability of gamma-ray interaction (photoelectric effect, the Compton effect, and pair production) was generated from a random number from 0 to. The ratio of undetected and incident photon in the detector were set 1:9, 2:8, 3:7, 4:6, and 5:5, respectively. The simulation results were then compared with the data measurement of Ga-67 spectrum energy from the spectrometer. The simulation results showed that the ratio of 2:8 gave the best result. Therefore, the Monte Carlo method attained build the simulation of Ga-67 energy spectrum. © 2021 American Institute of Physics Inc.. All rights reserved.
