The results obtained from the simulation are that the greater the photon energy fired at the NaI crystal material, the smaller the number of energy chopping particles stored in the material. The thicker the NaI crystal material, the more the number of energy chopping particles stored in the material if the same amount of photon energy is fired. The BIN energy width (BWIDTH) affects the distribution of the number of chopped particles for each energy level in the energy spectrum.
