摘要：

New reference materials (RMs), zirconium silicate, bauxite and phosphogypsum, were produced and characterized according to an ISO guide. The homogeneity of the three RMs was evaluated using X-ray fluorescence (XRF), and characterizations of the three candidate materials were performed through a collaborative study with nine expert radioanalytical laboratories. The assigned radionuclides are Th-230, Th-232, U-234, U-235, and U-238 for zirconium silicate; Th-230, Th-232, U-234, and U-238 for bauxite; and Ra-226, Th-230, U-234, and U-238 for phosphogypsum.
