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...

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...

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...

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,...
