Apatite Crystals

Gamma activation analysis on LUE NSC KIPT was used to measure macro-, microelements and 224,226,228RA in intact teeth and teeth with inflammatory odontogenic diseases. A comparative analysis of the phase composition of the teeth was carried out. It is shown that the size of apatite crystals in intact teeth is 3 times higher than in teeth with acute odontogenic diseases. The latter indicates the presence of an amorphous phase of carbonate inclusions and structurally unbound water

Precise Analysis

We present precise analysis of major and trace elements of the humic acid. We used three different element analytical techniques in our investigations as prompt-gamma activation analysis (PGAA), neutron activation analysis (NAA) and X-ray fluorescence (XRF) analysis was carried out. We identified 42 elements in our sample.

Manufacturing Techniques

The production and manufacturing techniques of metals involve expertise, and the study of ancient artifacts relies on interdisciplinary skills. Metalworking processes used in the production of jewelry masterpieces can, for example, give indications on the provenance of an ancient object of an unknown origin and the techniques used. In this regard, metallic samples from the Chiaravalle Cross (a beautiful processional cross with a complex structure, dating to the 13th century) have been studied, combining bulk and point measurements. Neutron-based experiments (like Prompt Gamma Activation Analysis and neutron diffraction) provide the bulk of the elemental and mineralogical composition, while particle induced X-ray emission analyses evidenced important details on its manufacturing techniques.
