%X Monte Carlo software MCNP and Geant4 were used to study the factors affecting the detection efficiency of the lanthanum bromide detector, mainly including the thickness of the detector al shell and the size of the crystal. The results of the two softwares were compared. The results show that only the thickness of the front Al shell increases the detection efficiency of the full energy peak, and the side al shell has little effect on the detection efficiency of the full energy peak; The increase of the radius length of the lanthanum bromide crystal will also increase the detection efficiency of the full energy peak. Comparing the results of MCNP and Geant4 simulation, it is found that the relative error of the two data is within 1%.
