| Abstract: | The feasibility has been shown of instrumental determination of the Na/Ca ratio with a standard deviation of 4.7% in sections of undecalcified bone tissue made from standard biopsy or autopsy bone samples (about 0.5 mg in weight) embedded in poly (methyl methacrylate) blocks. The determination was based on short-time activation and counting the24Na and49Ca radionuclides. Blank values and detection limits of the elements were evaluated and possibilities to detect changes of the Na/Ca ratio are discussed. |
