In the present work, we determined the gamma-ray attenuation characteristics of eight different polymers(Polyamide (Nylon 6) (PA-6), polyacrylonitrile (PAN), polyvinylidenechloride (PVDC), polyaniline(PANI), polyethyleneterephthalate (PET), polyphenylenesulfide (PPS), polypyrrole (PPy) and polytetrafluoroethylene(PTFE)) using transmission geometry utilizing the high resolution HPGe detector anddifferent radioactive sources in the energy range 81e1333 keV. The experimental linear attenuationcoefficient values are compared with theoretical data (WinXCOM data). The linear attenuation coefficientof all polymers reduced quickly with the increase in energy, at the beginning, while decrease more slowlyin the region from 267 keV to 835 keV. The effective atomic number of PVDC and PTFE are comparativelyhigher than the Zeff of the remaining polymers, while PA-6 possesses the lowest effective atomic number. The half value layer results showed that PTFE (C2F4, highest density) is more effective to attenuate thegamma photons. Also, the theoretical results of macroscopic effective removal cross section for fastneutrons (PR) P were computed to investigate the neutron attenuation characteristics. It is found that theR values of the eight investigated polymers are close and ranged from 0.07058 cm 1 for PVDC to0.11510 cm 1 for PA-6.
