We have studied the gamma/X-ray interaction parameters such as mass attenuation coefficient, mean free path (λ), half value layer, 10th value layer, energy-absorption buildup factors, and variation of electrical conductivity with the energy of gamma/X-ray between 1 keV and 100 GeV for Kondo insulators such as FeSi, Ce 3 Bi 4 Pt 3 , SmB 6 , YbB 12 , CeNiSn, CeRhSb, CeRuSn, and CeFeP. The variation of photon interaction parameters with incident energy of gamma/X-ray is graphically represented. We have also identified the X-ray absorption edges for the Kondo insulators. This identified X-ray absorption edges are useful in the characterizing of Kondo insulators such as FeSi, Ce
