In this study, the effects of lead-doped eyeglass samples at different energies on the radiation
shielding efficiency were investigated. Radiation shielding efficiency for samples were calculated using
the EGS4 code and discussed theoretically by comparing with XCOM data. Mass attenuation coefficients
(μ/ρ) for lead-doped eyeglass samples were investigated theoretically (WinXcom and EGS4) at gamma
ray energies between 59.5 and 1332 keV. Then, using the mass attenuation coefficients, it was determined
some shielding parameters such as mean free path (MFP), half value layer (HVL), one tenth layer
thickness (TVL), radiation protection efficiency (RPE), effective atomic number (Zeff) and gamma–ray
kerma coefficients (k
). It has been observed that lead (Pb) doping changes the parameters related to
radiation protection efficiency in eyeglass samples.
