Investigation of shielding parameters for smart polymers

In this work, the gamma and neutron shielding properties of 8 different types of smart polymers have been investigated. We have calculated the mass attenuation coefficient (mu/rho), effective atomic number (Z(eff)) and electron density (N-e) for total photon interaction in the wide energy range of 1 keVe100 GeV using WinXCom program. Furthermore, the macroscopic effective removal cross-sections (Sigma(R)) for fast neutron were calculated. The dependence of different parameters on incident photon energy and chemical content has been discussed. Among the selected smart polymers DMSO and PEI showed superior shielding properties for gamma-ray and neutron, respectively. This work was carried out to explore the advantages of the smart polymers in gamma-ray and neutron shielding applications. (C) 2016 The Physical Society of the Republic of China (Taiwan).
