Application of gamma activation analysis for research of Cs and I diffusion into a glassceramic matrix
Nuclear reactions ¹³³Cs(γ,n)¹³²Cs, ¹²⁷I(γ,n)¹²⁶I were utilized for research of Cs and I diffusion in glassceramic matrices. The glassceramic matrix was manufactured with the help of hot isostatic pressing at 910°C and pressure 100 MPa. Diffusivities of cesium and iodine in a grain and through interp...
