“…The non-mineralised tissues stained with Stevenel's blue in bone specimens may correspond to bone marrow and/or fibrous tissues (Rustom et al, 2016) and their presence could explain the additional regions observed in the neutron volume images. Bone marrow has a high hydrogen content and fibrous tissues are made of collagenous material, which were both reported to have a higher neutron attenuation than hydroxyapatite, the main component of mineralised bone tissue (Sołtysiak et al, 2018). So far, neutron tomography has only been sporadically applied to bone research Le Cann et al, 2017) and the ability to distinguish mineralised from soft tissues at high resolution has not been thoroughly investigated yet.…”

“…In this regard, relevant applications of combined neutron and X-ray imaging have been explored in different fields, like for example materials science, paleontology, medicine. In fact, it has been shown that the two techniques are complementary in studying fossil bones: neutron radiography penetrates hydroxyapatite easier than collagen and, conversely, in X-ray radiography attenuation is higher in hydroxyapatite than in collagen 45 .…”

Some cultured and natural pearls can be reliably distinguished by visual inspection and by the use of lens and microscope. However, assessing the origin of the pearls could be not straightforward since many different production techniques can now be found in the pearl market, for example in salt or freshwater environments, with or without a rigid nucleus. This wide range of products requires the use of new effective scientific techniques. Indeed, X-ray radiography has been used by gemologists since last century as the only safe and non-destructive way to visually inspect the interior of a pearl, and recently, also X-ray computed micro-tomography was used to better visualize the inner parts of the gems. In this study we analyzed samples of natural and cultured pearls by means of two non-destructive techniques: the X-ray Phase-Contrast Imaging (PCI) and the Neutron Imaging (NI). PCI and NI results will be combined for the first time, to better visualize the pearls internal morphology, thus giving relevant indications on the pearl formation process.

“…The examination of the cross section of the artefact was made by optical microscopy (OM) in order to determine the distribution of alloy layers. The arrangement of the technological layers of the artefact was examined by neutron imaging (NI) (Anderson et al 2009;Miśta et al 2015Sołtysiak et al 2018). A microinvasive LA-ICP-MS ( Fig.…”

“…In neutron imagining (NI) study (Pranzas 2008;Anderson et al 2009;Miśta et al 2015Sołtysiak et al 2018), the Maria research reactor located in the National Centre for Nuclear Research in Otwock, Poland (www.ncbj.gov.pl) was used as a neutron source. NI experiments were carried out with the NGRS station, which is a standard Dynamic Neutron Radiography facility.…”

A unique shield grip decorated with openwork rivet plates was found in a Roman Period cemetery of the Przeworsk culture in Czersk, Central Poland. The artefact underwent specialist analyses with the use of various techniques in order to reveal its silvering technology. Several silvering techniques were considered as the most probable: foil silvering, mercury silvering and silver plating. A number of complementary analytical methods such as laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), scanning electron microscopy with energy-dispersive X-ray (SEM-EDX), X-ray diffraction and neutron techniques were used in the examinations. Two silvering technologies were identified: foil silvering and mechanical treatment of silver pieces. On the basis of the specific correlation of maximum contents of silver (Ag), copper (Cu) and tin (Sn) in external layers of the artefact, it was found out that the surface of the openwork plates had been first covered with alloy with a high content of tin and copper as a solder. Then, a thin silver foil was applied onto it. On the other hand, combs of the shield grip were ornamented using non-soldering technology, i.e. hammering and punching.
