A simulation system based on personal computer in DOS environment has been designed to simulate the γ-ray measurement spectrum. The γ-ray spectra for reactor neutron activation analyses and the spectra of radionuclides can be simulated in this system on the basis of modeling for an experimental spectrum of 137Cs. In the spectrum， the photopeak， Compton edge， Compton plateau and backscattering peak are simulated. This system has functions of peak area calculating， spectrum shaping， spectrum displaying， spectrum processing and spectrum saving， etc. Using this simulation system， the γ-ray spectra of 137Cs， 60Co， 152Eu and the spectra of Zr sample， rock standard sample for reactor neutron activation analyses have been simulated. The simulation spectra are similar to the spectra measured in the actual experiment to a great extent.
