Abstract

Gamma ray shielding ability of WO3 borate glasses is analyzed by using the Phy-X/PSD software. Mass attenuation coefficient of glasses gets enhanced with addition of tungsten oxide resulting in lowering of the values of MFP, HVL, TVL and EBF at 10 mol % of tungsten as compared to many commercial and radiation shielding glasses/concretes. The higher value of FNRCS (∑R) in studied glasses than concretes shows their neutron shielding ability. The sample with highest value of tungsten is most suitable for making radiation shielding materials. The OPD, OMV, n¯c, nb and dbb values indicate the rigid and stable glass structure due to the formations of stable BO4 groups. Poisson ratio confirms high cross density and stability of prepared glasses as its value decreases from 0.233 to 0.226. The increased values of elastic constants and VHN are also in the favour of higher stability and rigidity of the glasses due to addition of WO3. All of these parameters are in good relation with each other and support the shielding power of the studied glasses.
