  1. 11. PGAI-NT, an integrated approach of element analysis and imaging, and its applications to cultural heritage samples
    Dr László Szentmiklósi (Centre for Energy Research, Hungarian Academy of Sciences)

    Prompt gamma activation analysis
    Invited speaker
    Most widespread element analysis techniques are not suitable for bulky heterogeneous or structured objects. Prompt-gamma activation imaging (PGAI), in combination with neutron tomography (NT), has proven its potential to fill this niche, thanks to the non-destructive nature and the high penetration depth of neutrons and gammas. This is of utmost importance for valuable cultural heritage...

  3. 36. Preliminary petrological and geochemical results of the possible source locations of HP-metaophiolitic polished stone artefacts

    Prompt gamma activation analysis
    Oral presentation
    In NW-Italy most of the Neolithic polished stone artefacts (axes, adzes, chisels) are manufactured from high pressure and low temperature metaophiolites – greenstones – but they widespread everywhere in Europe also [1, 2, 3]. In the last 10 years in Hungary 25 prehistoric polished stone tools were identified during the re-examination of the Museum historical collections [4]. The specialty of...

  4. 39. Archaeometry at the PGAA facility of the MLZ
    Dr Christian Stieghorst (Heinz Maier-Leibnitz Zentrum (MLZ), Technical University of Munich)

    Prompt gamma activation analysis
    Oral presentation
    Instrumental neutron activation techniques such as prompt gamma activation analysis (PGAA) and instrumental neutron activation analysis (INAA) are well-suited for archaeometrical applications. A bundle of advantages make these methods attractive for archaeometry and cultural heritage, for instance low destructiveness, straightforward sample preparation and good detection limits for many...

  5. 35. Quantitative chlorine analysis of archaeological iron objects by PGA Analysis
    Dr Britta Schmutzler (State Academy of Art and Design Stutttgart)

    Prompt gamma activation analysis
    Oral presentation
    **Background** Archaeological iron objects usually suffer from post excavation corrosion, induced by chlorine, which diffuses into iron objects during burial. Objects conservation has the task to extract the chlorine by e.g. washing methods since the destruction of this corrosion form is drastic and hard to control by climate conditions. Several approaches were developed the last decades,...
