Abstract Cross denars, frequently found in Polish hoards, were traditionally thought to be Ag coins with some Cu content. This study investigates the possibility of a hidden core beneath or Ag–Cu surface these coins. It raises questions about whether they counterfeits intentionally designed for mass production. Unlike Roman denarii, which revealed their cores when broken, examination cross denars without damage is challenging. Optical microscopy and microanalysis differences composition...
Abstract This paper presents the findings of a study on dose rate distribution in air and water phantoms, recorded using Gafchromic films. Low energy accelerator with X-ray tube (NALR), system developed at National Centre for Nuclear Research (NCBJ), generated by rates. The primary objective this research was to employ as source radiation assess dosimetry techniques radiochromic films radiological protection purposes. MD-55-V2 EBT were utilized measurements. Two-dimensional measurements...
The Migration Period on the present Polish territories is considered as a time of depopulation Oder, Warta, and Vistula basins.The prerequisite for such assumption lack archaeological finds in these regions.In contrast, Mrągowo Lake District Lyna basin, one can find wealth burial crematory equipped with items from Roman period made Germanic style.The analyses using physics techniques gives an opportunity to meeting history contemporary times lost things may see light day.The discovered...
Abstract LaBr 3 :Ce,CeBr and GAGG:Ce scintillators were investigated the determined characteristics compared with those obtained for well-known widely used CsI:Tl NaI:Tl crystals. All detectors of same size 10 × 5 mm . The aim this test study was to single out scintillation most suitable γ-ray spectrometry emission radial profile measurements in high-temperature plasma experiments. Decay time, energy resolution, non-proportionality full peak detection efficiency ere measured energies up 1770...
The formation of the $[1s2s]$ $S$ states in heliumlike uranium $({\mathrm{U}}^{90+})$ has been studied relativistic collisions initially lithiumlike $({\mathrm{U}}^{89+})$ ions with ${\mathrm{N}}_{2}$ target molecules. By measuring projectile x-ray emission coincidence ionization, a strong selectivity for is observed. This found to be unaffected by subsequent rearrangement atomic orbitals involved. photon associated decay $^{1}S_{0}$ and $^{3}S_{1}$ substates, we obtain their relative...
This article presents a detailed analysis of the $K\ensuremath{\alpha}$ x-ray spectra Si induced by $11.4$ MeV/u Ca projectiles penetrating low-density SiO${}_{2}$ aerogel target measured with high spectral and spatial resolution at UNILAC accelerator GSI-Darmstadt. The material used in experiment was crucial for space-resolved studies radiation (for different energies stopping ions). length $11$ ions reaches up to $10$ mm aerogel, whereas regular quartz solid targets it is about $100$ times...
Abstract Scanning electron microscopy with X-ray microanalyses (SEM-EDX) was used for a technological study of silver jewellery from three hoards found in Poland. The assemblage consists 26 artefacts the period formation first Polish state (900–1039 AD) and can be divided into groups: West Slavic, post-Moravian Scandinavian. Research results provide information concerning techniques granulation ornament provenance raw silver. Elemental composition changes are manifested mainly by different...
Abstract The Bronze and Early Iron Ages witnessed a significant increase in trade relations driven by the search for valuable metals. This paper presents new insights into use of galena from Silesia Krakow Upland region southern Poland, known as ‘Olkusz ore deposits’, within context metal ores prehistoric Europe. Eleven lead‐based ornaments Lusatian Urnfield Culture cemeteries were examined using lead isotope analysis. majority these found to be made local ore, which provides evidence early...
Abstract The aim of this paper is to discuss technological details medieval jewellery on the basis studies five lunulas (the Obra Nowa hoard, Poland). types soldering which were applied in order attach granules and wire artefact surface studied with use optical microscopy, scanning electron microscopy energy dispersive X‐ray spectroscopy, micro‐Raman spectroscopy diffraction. Results confirmed chemical that was based Cu compounds resin glue addition. such addition can be assumed due fact C...
The lack of known tin deposits in Poland requires that the source metal ancient artifacts must be derived from foreign sources. To identify these external sources, a combination Pb and Sn isotope compositions trace element analyses on group rich alloys three settlements Viking to medieval times was conducted. integration chemical techniques reveals several sources for artifacts, where group: 1) possesses values overlap Europe array which possess highest (+1.6‰) lowest (-1.1‰) coupled with...
The numerical simulations of Cu Kα and Kβ fluorescence lines induced by Rh X-ray tube monoenergetic radiation have been presented. copper Kβ/Kα intensity ratios for pure elements as well Ag-Cu alloys modeled. results obtained use the FLUKA code, based on Monte-Carlo approach, compared to available experimental theoretical values. A visible relationship was found between simulated content alloy: increases, coefficient decreases. can play role in elemental material analysis, especially archaeometry.
A unique relief fibula dated to the Migration Period (first half of sixth century) was found in Radziejów, Poland. This stray find changes previous opinions on lack settlement central Poland at that time. As is only one such type Poland, a special attention paid possible analogies, mainly finds from Scandinavia and Western Europe. The underwent technological analyses order reveal its technology manufacture. For this purpose, chemical elemental composition alloy studied. Several...
Soft x-ray emission from a Mather-type plasma-focus device (PF-1000) operated at ∼400 kJ was measured. The high density and temperature plasma were generated by the discharge in deuterium-argon gas mixture modified (high-current) configuration. A spherically bent mica crystal spectrograph viewing axial output of pinch region used to measure spectra. Spatially resolved spectra including characteristic lines highly ionized Ar continua recorded means an film. PF-1000 studied different areas pinch.
The ED-XRF (Energy-Dispersive X-ray Fluorescence) measurements and the FLUKA simulations have been made to discuss possibility of recognition coating layer as well its thickness measurement. In this work IKα(Cu)/IKα(Ag) intensity ratios IKβ(Ag)/IKα(Ag) IKβ(Cu)/IKα(Cu) for copper samples coated with various sputtered silver analyzed. results show strong dependence these factors thickness. performance method in archaeometry. Since use non-destructive methods during tests on ancient artifacts...
A unique shield grip decorated with openwork rivet plates was found in a Roman Period cemetery of the Przeworsk culture Czersk, Central Poland. The artefact underwent specialist analyses use various techniques order to reveal its silvering technology. Several were considered as most probable: foil silvering, mercury and silver plating. number complementary analytical methods such laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), scanning electron microscopy...
