Description

A Monte-Carlo model of internuclear cascades, supplemented with a programme calculating the gamma-radiation spectra, emitted by excited aftercascade nuclei is used to investigate characteristics of induced gamma-activity in structural materials Al, Ti, Fe, W, Pb and in one of the alloys exposed to the influence of cosmic particles and albedo neutrons on close-to-earth orbits. Spectral distributions of activational gamma-radiation are calculated. It is shown that the induced radioactivity is comparable and in some of the energy intervals even exceeds the background gamma-radiation on the orbit. 18 refs.; 5 figs
