The Effect of Small Doses of Gamma Radiation on the Structural Characteristics in Silicon

Experimental studies were carried out by two different sources of gamma quanta. Samples were irradiated gamma - quantum radioisotope source 226Ra and electron accelerator braking gamma radiation - betatron Saratov state university. The form of the diffractograms shows the high crystallinity of the samples under study. The effect of gamma rays of radium led to a slight shift of the maximum of the reflex relative to the angle 2θ=29.18° to the left and a decrease in its width. The structure of the samples irradiated with γ-quanta of the bremsstrahlung of the betatron, according to the measurements, has undergone more significant and unexpected changes.
