Abstract A computer method has been developed that simulates gammaray spectra of geochemical thermal neutron activation experiments. The input for the simulation includes the designation of rock type, neutron flux, sample volume and density, irradiation time, time of detection start, duration of monitoring, and number of analyzer channels. The output of the simulation includes either two-or threedimensional computer drawn plots of the resulting (simulated) gammaray spectra. The threedimensional plots (energy vs counts per sec vs time of detection) allow the investigator to observe the apparent appearance and disappearance of photo peaks, annihilation peaks, and pair production peaks of the various isotopes as a function of time. Various combinations of irradiation, delay, and detection times result in various spectral patterns. The resultant patterns accurately simulate the real activation experiments run under the same time conditions. The simulated spectra are useful for identifying peaks obtained from real spectra, helping in radiochemical separation decisions, and, in general, in designing the neutron activation experiment.
