Description

Among the phosphates considered as waste forms for long-lived radionuclides, monazite stands out because of its low solubility, slow dissolution rate and high chemical flexibility to incorporate actinide elements such as Am and Cm. EXAFS was carried out to evaluate the local structure of the Sm1-xTbxPO4 solidsolution between the Sm endmember with monazite and the Tb endmember with xenotime structure.
