Investigating the effects of Erbium (Er) doping on the radiation shielding properties of
Bi2Sr2(Ca1-xErx)Cu2O8 (x = 0.0, 0.1, and 0.3) polycrystalline superconducting ceramics is the goal of the
current work. Both the WinXcom database and the EGS4 Monte Carlo simulation algorithm were used to
theoretically estimate the mass attenuation coefficients (u/p) of the produced samples across a range of
gamma-ray energies. The mean free path (MFP), half value layer (HVL), radiation protection efficiency
(RPE), effective atomic number (Zeff), and gamma-ray air kerma coefficients (k
) were among the
important shielding characteristics that were methodically determined from these coefficients. The
shielding performance was thoroughly evaluated using the EGS4 simulations, and any discrepancies were
identified by rigorously comparing the outcomes with the theoretical predictions derived from XCOM.
First, the Er-doped Bi-Sr-Ca-Cu-O superconducting system's physical and structural characteristics were
carefully investigated. Er incorporation dramatically alters the radiation attenuation behavior, according
to
subsequent comparisons between the Er-doped and undoped samples. This improves our
comprehension of the compositional dependency of shielding efficiency in BSCCO-based
superconductors.
