Sažetak
Neutron activation analysis (NAA) is a nuclear analytical technique that utilises the specific properties of nuclear reactions, thereby enabling simultaneous determination of numerous elements in a sample. Due to its sensitivity, versatility and high reliability, NAA is the most prominent of all the activation techniques. The idea of using the k0-method of instrumental neutron activation analysis (k0-INAA) for analytical purposes appeared in the early 1970s, where the absolute nuclear data are replaced with k0-factors that are experimentally determined. It uses Au as the standard (Al-0.1%Au alloy) irradiated together with a sample and nuclear composite nuclear constants for analytically interesting nuclides are normalised to Au nuclear data. The k0-method at the Department of Environmental Sciences of the Jožef Stefan Institute (IJS) has been introduced in the middle 1990s and validated, and since then it has been used for routine analyses for determining micro and trace elements in different environmental samples. In addition, the k0-INAA at the 250 kW TRIGA Mark II research rector of the IJS has been accredited according to the ISO 17025 for determining elemental composition in environmental samples since 2009. In this work, the k0-INAA technique was applied for determination of minor and trace elements in samples of sewage sludge-amended soil. Some preliminary results of the study will be presented and discussed.
