The authors present a technique for optimizing the gamma activation analysis of trap rock using the OPTIMUM program. Comparative results are presented for the calculated and measured radioactivity, in optimal regimes of the gamma spectra, induced by the bremmstrahlung from electron accelerators in standard samples of igneous trap rock. The optimization criterion employs the functions associated with the error in the measurement of the area of the photopeak and the limit of detection for each element. 92 stable isotopes of 44 elements, from which radionuclides emitting 274 gamma lines were formed in 113 photonuclear reactions, were taken into account.
