“…Selecting composition and energy radiation can ensure the prevalence of that kind of interaction, which contributes to maximizing information about controlled sample (Athanassiadis 1994). Depending on the effects of interaction of γ-quant with matter and scattering geometry there are resonance and non-resonance absorption methods of scattered radiation, as well as combined methods of γ-control (multi-beam methods) (Athanassiadis, Anshakov et al 1993;Athanassiadis 2007;). …”
