Evaluation of Gamma-Ray Sensing Parameters for Some Oxides of Lanthanides

Abstract

Abstract We attempted to investigate gamma-ray sensing properties of selected oxides of lanthanides over wide gamma-ray spectrum. The effective atomic number (Zeff) and optimum thickness range are calculated for some oxides of rare-earth lanthanides: La2O3, Sm2O3, Eu2O3, Er2O3, Yb2O3, Lu2O3. These photon attenuation and sensing parameters were calculated using the online Py-MLBUF program. Among the lanthanide oxides investigated, lutetium oxide (Lu2O3) is found to possess higher effective atomic number and relatively smaller optimum thickness range which makes it a suitable choice for radiation sensing applications.
