| Abstract: | This paper presents the results of a study of thermal properties, solubility and response to 60Co γ-rays by electron spin resonance of the P2O5–CaO–Na2O glass system. The sample compositions were selected by fixing the P2O5 mol% content at 50 mol%, and varying the CaO mol% at 30 and 40 mol%. The spectrum is characterized by hyperfine doublet from 31P isotope (nuclear spin = 1/2), and its stability and response to the γ-ray dose were studied to establish the suitability of this glass as a γ-ray dosimeter. |
