    ABSTRACT: Gamma ray shielding effectiveness of superconductors with a high mass density has been investigated. We calculated the mass attenuation coefficients, the mean free path (mfp) and the exposure buildup factor (EBF). The gamma ray EBF was computed using the Geometric Progression (G-P) fitting method at energies 0.015–15 MeV, and for penetration depths up to 40 mfp. The fast-neutron shielding effectiveness has been characterized by the effective neutron removal cross-section of the superconductors. It is shown that CaPtSi3, CaIrSi3, and Bi2Sr2Ca1Cu2O8.2 are superior shielding materials for gamma rays and Tl0.6Rb0.4Fe1.67Se2 for fast neutrons. The present work should be useful in various applications of superconductors in fusion engineering and design.

    ABSTRACT: In the present work, we computed the g -ray interaction characteristics of some boron containing ma- terials such as B 3 Al 2 O 3 , B 4 C, B 10 H 14 and ferro-boron (FeeB) 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 0.015e15 MeV up to penetration depth of 40 mean free path. The FeeB is found to be the superior g -ray shielding material. The results of the present work could be useful in radiation shielding applications in various neutron sources, reactors and accelerators.

    ABSTRACT: Manjunath et al 16  Abstract:-Mass attenuation coefficient and effective atomic number of the active pharmaceutical ingredients viz, Alprazolam, Amiodar, Amiodarone, Ciprofloxacin, Diclofenac Sodium, Femotidine and Nimesulide have been calculated over a wide energy range from 1 keV to 100 GeV for total and partial photon interactions by using WinXCom. The estimated data results in change of mass attenuation coefficient and electron density are varies with energy and chemical composition of the active pharmaceutical ingredients (API's) in drugs. The results are discussed in the light of photon interaction with energy and effective atomic number of the API's in drug are shown in the logarithmic graphs.
