Gamma ray attenuation coefficient calculation methods used to accurately study the properties of lead borate such as (30.4PbO-69.6B2O3). In this study, mass attenuation coefficients (µm) of these lead borate for 0.122-, 0.356-, 0.511-, 0.662-, 0.884-, 1.170, 1.275-, 1.330- MeV photons are determined using the radio-nuclides Co57, Ba133, Cs137, Na22, Mn54, and Co60. NaI (Tl) scintillation detection system. The attenuation coefficient values (µm) and linear attenuation coefficient (µ) of lead borate. Theoretical values were calculated with the help of XCOM data. Theoretical and experimental values are found to be in a good result. The variations of µm and µ with energy are shown graphically. The values of µm and µare higher at lower energies, and they decrease sharply as energy increases.
