Abstract
The results of isotope identification of nuclear materials (232Th, 235U, 238U, 239Pu) packed in hermetic stainless steel containers by their stimulated delayed gamma radiation are presented. The ratios of the values of the time dependences of the intensity of gamma radiation of the light and heavy product of their photofission were used for the analysis. Gamma radiation from photofission products 89Rb (1031.9; 1248.1 keV) and 138Cs (1009.8; 1436.8; 2218.0; 2639.6 keV) was used to differentiate nuclear materials. The photofission reaction the samples of nuclear materials was stimulated on an electron accelerator, an M-30 microtron, at maximum bremsstrahlung energy of 12.5 MeV. The possibility of carrying out isotopic identification of nuclear materials using the following sets of ratios of the values of the time dependences of the gamma-line intensity has been demonstrated: X(1031.9)/X(2639.6), X(1248.1)/X(1009.8), X(1248.1)/X(1436.8), X(1248.1)/X(2218.0), X(1248.1)/X(2639.6).
