Multi-element determination in standard Horse Kidney and human organ tissues by instrumental thermal neutron and photon activation analyses

The elemental abundances in the International Atomic Energy Agency standard reference material Horse Kidney (H-8) were determined in the framework of the research project on Intercomparison of Cadmium and Other Elements in IAEA Horse Kidney. Instrumental thermal-neutron and photon activation analyses were applied to the multi-element determination in this standard material. This material was then tested for use as a comparative standard for the multi-element analysis of related biological materials; human liver and kidney tissues. The National Bureau of Standards Orchard Leaves and Bovine Liver were also used as comparative standards. Merits and comments are given on the basis of their applicability and versatility as multi-element reference materials. (author)
