γ-ray interaction characteristics for some boron containing materials

• γ-ray interaction characteristics for B3Al2O3, B4C, B10H14 and ferro-boron is studied.
• Exposure buildup factors were calculated using G-P fitting method.
• Fe–B is found to be the most efficient shielding material.
• In low-energy the EBF converges whereas diverges for high-energies.

In the present work, we computed the γ-ray interaction characteristics of some boron containing materials such as B3Al2O3, B4C, B10H14 and ferro-boron (Fe–B) by means of effective atomic numbers and exposure buildup factors (EBF). The EBF of the materials were calculated using Geometric Progression (G-P) fitting for photon energy range 0.015–15 MeV up to penetration depth of 40 mean free path. The Fe–B is found to be the superior γ-ray shielding material. The results of the present work could be useful in radiation shielding applications in various neutron sources, reactors and accelerators.
