Description
Summary:A way is suggested of solving problems of determination of optimal sensitivity in radiographic image visualization systems. Means for elaborating such systems for conventional radiography are considered, and these consist of combining intensifying screens with film, and for computed radiography, which is based on use of image storing screens. Special attention is devoted to the BaFBr:Eu phosphor—to the nature and distribution of defects in it and to the mechanism of its photo-stimulated luminescence. The important role of defect segregation, of anti-structural disordering of Frenkel type and of the diffusional mechanism of electron migration involving trapping is noted.
