Comparative Study of Radiation Shielding Parameters for Bismuth Borate Glasses

Authorship SCIMAGO INSTITUTIONS RANKINGS

Melt and quench technique was used for the preparation of glassy samples of the composition x Bi₂O₃-(1-x) B₂O₃ where x= .05 to .040. XCOM computer program is used for the evaluation of gamma-ray shielding parameters of the prepared glass samples. Further the values of mass attenuation coefficients, effective atomic number and half value layer for the glassy samples have been calculated in the energy range from 1KeV to 100GeV. Rigidity of the glass samples have been analyzed by molar volume of the prepared glass samples.
