Abstract The photon interaction parameters viz. Mass attenuation coefficient (μm), effective atomic number (Zeff), effective electron density (Ne), Half Value Layer (HVL) and Mean Free Path (MFP) of x P b O − ( 40 − 0.5 x ) B 2 O 3 − ( 40 − 0.5 x ) P 2 O 5 − 9.0 N a 2 O − 1.0 A l 2 O 3 − 9.6 Z n O − 0.2 S m 2 O 3 − 0.2 G d 2 O 3 ( x = 10 , 15 , 20 , 25 , 30 , 35 ) of glass system are measured at energies 59.54 keV, 356 keV, 662 keV, 1173 keV and 1333 keV. Scintillation detector [NaI(Tl), 3 ' × 3 ' has been used for these measurements. The experimental values of μm have been compared with the values obtained with the help of WinXcom and the comparison shows a good agreement of the values with each other within experimental uncertainties of 3.5%. The parameters μm, Zeff and Ne are energy dependent and vary from the higher value at lower energy to the lower value at higher energy. The values of HVL and MFP fall from 67% to 42% with the increase of Pb concentration whereas these values rise with the increase in incident photon energies from 59.54 keV to 1333 keV. This suggests that the presence of PbO improves the radiation shielding properties of lead alumino-borophosphate glasses. This study is usefulness to explore the feasibility of borophosphate glasses for developing high energy radiation sensors and detectors.
