Neutron Shielding and Elastic Moduli Properties of Dysprosium Doped Sodium-based Oxide and Oxyfluoride Glass Systems

The dysprosium doped sodium–based oxide and oxyfluoride glass systems were studied for their neutron shielding and elastic modulus properties. Fast neutron removal cross–section (SR, cm–1) was determined by partial density theory. The elastic moduli of glass systems were estimated theoretically by Makishima–Mackenzie (M–M) model. The fast neutron removal cross–section value of dysprosium doped sodium–based oxyfluoride had higher than sodium–based oxide glass systems that indicated oxyfluoride glass system had superior shielding properties than oxide glass system. Moreover, the values of elastic moduli properties for oxyfluoride had higher than also. Keywords: Oxyfluoride glass, Fast neutron, Elastic moduli
