Abstract
Differences in the attenuation of γ rays by nanostructural materials as compared with ordinary materials are examined. The characteristic features of scattering by the structural units of a nanostructural material and the propagation of γ rays are discussed on the basis of a solution of the transfer equation. The contribution of total surface reflection at internal boundaries of such a material to the increase in the absorption of γ rays is estimated. The optimal size of structural units of a nanostructural material for which maximum γ-ray absorption obtains is estimated to be 3.4–4.4 nm. Nanostructural materials provide more protection from γ radiation than do ordinary materials.
