Abstract :
The present work is concerned with the determination of linear attenuation coefficient, mass attenuation coefficients, the effective atomic number and electron density for different leaded glass composites by 60Co gamma-ray source. Linear attenuation coefficient (μ) has been measured by the transmission method in a good geometry setup. The measurements have been carried out using a collimated beam emerging from 60Co radioactive source and the NaI(Tl) scintillation detector. Also, NCNP5 code has been used to calculate (μ) by modeling the experimental technique. The mass attenuation coefficients (μ/ρ) have been achieved using the evaluated linear attenuation coefficients (μ). The effective atomic number (Z eff) and electron density (N el) have been calculated depending on the experimental results. Also, WinXCom program has been used to compute the same parameters theoretically. The general trend of the calculated parameters show increase with the increasing of PbO concentration.
