Abstract

Mass attenuation coefficients of the YBaCuO and BiPbSrCaCuO superconductors were determined at 511,661, and 1274 keV photon energies. The samples were irradiated using 0.5 mCi Cs-137 and 2 mCi Na-22 radioactive sources. The photons crossing the samples were counted using a multi-channel analyzer with a NaI(Tl) detector. The Nucleus II software was used to analyze the spectra. It was observed that the mass attenuation coefficient decreases with increasing energy and increases with increasing atomic number.
