Certified reference material (CRM) for natural ( 40 K, 210 Pb, 210 Po, 226 Ra, 228 Ra, 228 Th, 230 Th, 232 Th, 234 U, 235 U, and 238 U) and anthropogenic ( 137 Cs, 239+240 Pu, and 241 Am) radionuclides in marine sediment from the Baltic Sea (IAEA-465) has been developed. Information values are given for 238 Pu, 239 Pu and 240 Pu. Altogether 27 laboratories participated in this exercise. Radiometric (alpha-spectrometry, gamma-spectrometry and beta counting, as well as mass spectrometry (ICP-MS and AMS) techniques were applied in measurements. The CRM is intended to be used for Quality Assurance/Quality Control of radionuclide analyses, for the development and validation of analytical methods, for the development of reference methods and for training purposes.
