Instrumental neutron activation analysis of geological and biological reference materials using the ko-standardization method

  • M. Carmo Freitas
Neutron Activation and Related Methods


The ko-standardization method used in instrumental neutron activation analysis (INAA) was applied to the determination of some elements in geological and biological reference materials. We analyzed NBS SRM 1572 Citrus Leaves and SRM 1645 River Sediment and the CRM materials, IAEA Soil-7, SL-1, and MA-A-2. Comparison is made with reference values whenever available. Good agreement is found. The potential of the ko-standardization method in reactor INAA is discussed.
