Abstract: | Instrumental neutron activation analysis with the k0-standardization method was applied to eight geological, environmental and biological reference materials, including leaves, blood, fish, sediments, soil and limestone. To a first approximation, the results were normally distributed around the certified values with a standard deviation of 10%. Results obtained by using the relative method based on well characterized multi-element standards for IAEA CRM Soil-7 are reported. |
