The development of inexpensive radiation-resistant glass is important for potential applications in displays, optics, and nuclear or space environments. This study considers the γ-ray X-ray resistance glasses relevant to low-cost float (i.e., SiO2–Na2O–CaO–MgO), modified with various concentrations (0 – 10 mol%) Sb2O3. Various doses (0, 0.2, 2.0, 5.0 MGy) γ-rays from decay 60Co nuclei, X-rays g...
