摘要：
The feasibility of nonstationary modes of the diffusion gas tracer tomography for decoration of various structural defects in heterogeneous materials was studied. The features of autoradiographic permeability procedure with respect to alpha- and beta-emitting tracers were analyzed by methods of mathematical simulation, This made of permeability procedure with successive registration of autoradiographic patterns from the outlet side of the plate allows monitoring of the diffusion process in the separate structural defects. The nonstationary mode of the gas tomography provides decoration of structural defects and evaluation of their diffusion resistance to the gas tracer.
