    Neutron Activation Analysis (NAA) is a well established method for non-destructive determination of elemental composition and the analysis of trace elements. Prompt Gamma Neutron Activation Analysis (PGAA or PGNAA) is a complementary radioanalytical technique to NAA for non-invasive investigations of samples with neutrons. One of the main advantages of this latter technique is the easy...

    Various trace elements in different types of iron based geological reference materials [JSS 804-1 (hematite), JSS 820-2 (limonite), SU-1 and SU-1a (iron-nickel-copper-cobalt ores)] were investigated using k0-NAA in both forms: instrumental (k0-INAA) and radioanalytical (k0-RNAA). To avoid the interference of iron as a matrix element, firstly mineral was dissolved in aqua regia then...

  3. 253. The impact of polyethylene vials on reactor channel characterization in k<sub>0</sub>-NAA

    Nuclear Analytical Methods
    Verbal
    Reactor channel characterization is commonly performed by irradiation of bare and cadmium-covered "fluence rate-monitors", avoiding as much as possible the use of irradiation vials/capsules and spacers for positioning the monitors inside the channel. However, in routine k0-Neutron Activation Analysis is generally necessary to pack the samples in polyethylene vials prior to...
