Abstract

In the present investigation, we have determined here the mass attenuation coefficients (μm) of germanium oxide for energies of 122 -1330 keV. Photon energies are measured using the different radioactive sources Co57, Ba133, Cs137, Na22, Mn54 and Co60. In the current investigation to detect gamma rays NaI(Tl) scintillation detection system were used. The investigated attenuation coefficient values were then used to determine the important parameters i.e. total atomic cross sections (st) for germanium oxide. Graphically it is observed that the variations of μm and st with energy The values of μm, st, are higher at lower energies and they decrease sharply as energy increases. The XCOM data is used to calculate Theoretical values. We were observed that the Theoretical and experimental values are found to be in a good agreement (error < 3-4%).

Keywords: attenuation coefficient, total atomic cross sections
