Description 274-282
Lightweight epoxy-based X-ray /gamma-ray shielding materials were synthesized by blending epoxy resin with the
different weight percent of lead oxide, bismuth oxide, and tungsten oxide powders. The synthesized composites were
characterized using FTIR, elemental analyzer, and X-ray radiography for their chemical structure, elemental composition,
and filler distribution. The photon interaction parameters such as linear/mass attenuation coefficient, attenuation percentage,
and half value layer were determined for all composites at photon energies 59.5, 364, and 661.7 keV. The measured mass
attenuation coefficients of epoxy composites matched well with the obtained from XCOM. Moreover, the shielding
effectiveness of the composites was analyzed by the half-value layer and heaviness of the composites and was compared
with conventional shielding materials (concrete, lead, and steel).
