Abstract Objective The method of Monte Carlo efficiency transfer was applied to determine full energy peak efficiency of the LaBr3 detector.Methods The method of Monte Carlo efficiency transfer was introduced, and the efficiency transfer factors of the LaBr3 detector were calculated based on the point-source experiments. At last, the results of calculated full energy peak efficiency were compared with the measured values.Results The comparisons between calculations and point source experiments showed that the relative deviations were mostly within ±5% in the energy range of 121.8~1332.5 keV.Conclusion The results showed that the mothed of virtual calibration was more feasible with Monte Carlo efficiency transfer.
