Dosimetric features and kinetic parameters of a glass system dosimeter

Lithium borate (LB) glasses doped with dysprosium oxide (Dy2O3) have been prepared by utilizing the conventional melt-quench technique. The prepared glass samples were exposed to 60Co to check their dosimetric features and kinetic parameters. These features involve glow curves, annealing, fading, re...
