Abstract

Lanthanides, a group of rare earth elements, have attracted considerable attention due to their unique properties and valuable applications. In this study, the albedo parameters of three distinct groups of lanthanide compounds (Cerium, Gadolinium, and Samarium) were investigated using 661.62 keV gamma radiation emitted from a137Cs radioactive source and a high purity germanium detector in backscattering geometry. Additionally, the mass attenuation coefficients of lanthanide compounds were examined in absorption geometry. It was found that Cerium III fluoride, Gadolinium III sulfate, and Samarium III sulfate exhibit the highest albedo numbers among the lanthanide compounds. Furthermore, an exponential relationship between albedo values and mass attenuation coefficients was observed. This study concludes that molecular groups attached to the same atom can influence the photon scattering properties.
