The mechanical features evaluated theoretically using Makishima-Mackenzie's model for glasses xBaO-(50-x) PbO–50P2O5 where x = 0, 5, 10, 15, 20, 30, 40, and 50 mol%. Wherefore, the elastic characteristics; Young's, bulk, shear, longitudinal modulus calculated. obtained result showed an increase in calculated values of moduli with replacement PbO by BaO contents. Moreover, Poisson ratio, micro-hardness, softening temperature investigated glasses. Besides, gamma neutron shielding ability barium doped lead phosphate Monte Caro code (MCNP-5) Phy-X/PSD program applied to estimate mass attenuation coefficient studied decrease ratio has a negative effect on MAC. highest MAC decreased from 65.896 cm2/g 32.711 at 0.015 MeV BPP0 BPP7, respectively. EBF EABF that contents BPP helps reduce number photons accumulated inside
