The Attenuation Of Gamma-Ray By Doped Azo Polymers With Nano Oxide Metals

The mass attenuation coefficient 26956m for pure polyamide C26 H26 N6 O2and pure polyazomythen C26 H18 N6 were measured at 59511 and 622 keV photon energies. The samples were separately irradiated with241Am22Na 137Cs radioactive gamma sources. The mass attenuation coefficient 26956m for composites materials from this polymers and nano oxide CuO and Co3 O4were measured using the same gamma sources. The relationship between the values of 26956m 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.
