One day duplicate diet samples of 30 Korean geriatric population over 60 years old were collected. Samples were analyzed by NAA(Neutron Activation Analysis) after a sample preparation such as a homogenization and a freeze-drying. SRM(Standards Reference Materials) from NIST were analyzed for a quality control of the analytical method. Analytical results were classified into two groups such as macro elements(Ca, K, Mg, Na) and minor elements(Cr, Fe, Mn, Se, Zn). Analytical results for a daily intake of the geriatric population in Korea showed that the macro and minor elements were lower than the RDA and literature except for Na. In conclusion, NAA is proved to be a sensitive analytical method useful for performing both a qualitative and a quantitative multi-elemental analysis of the macro and minor elements in a diet or biological materials.
