| Abstract: | A river kind of sediment Certified Reference Material (CRM) based on natural-matrix for environmental radioactivity has been developed. Nine natural and artificial radionuclides in the CRM were certified by two or more laboratories with one or more methods. The sample preparation, homogeneity test, stability inspection and the methods and results for radionuclide certification are described. |
