Problems of remote detection of chemical explosives and fissile materials using neutron-activation diagnostics method

摘要

This paper presents results of computer simulation of nuclear processes (using Geant4 9.0 package) for neutrons passing through a shell-free explosive model and through a model of military load containing some fissile material. Spectral distributions of γ-quanta were calculated for the neutron with fixed energy at different points of time after irradiation. The programs were designed using C++ and function under execution control of OS Red Hat LINUX 6.2 FEDORA.
