ABSTRACT
The mass attenuation coefficient (μ_m) for pure polyamide C_26 H_26 N_6 O_2and pure polyazomythen C_26 H_18 N_(6 )were measured at 59,511 and 622 keV photon energies. The samples were separately irradiated with(_^241)Am,(_^22)Na, (_^137)Cs, radioactive gamma sources. The mass attenuation coefficient (μ_m) for composites materials from this polymers and nano oxide CuO and Co_3 O_4were measured using the same gamma sources. The relationship between the values of (μ_m) versus gamma energies, and exist the attenuation of gamma ray increases with increasing the doping ratio specially at energy 59 keV.The samples that dope with two nano oxide best from samples that dope with one nano oxide.
