Opis:
In this study, the K shell intensity ratios $K_{β}/K_{α}$ have been experimentally determined for the elements Cr, Mn, Fe, and Co. Measurements have been carried out at 8.735 keV excitation energy by using secondary excitation method. K X-rays emitted by samples have been counted by a Si (Li) detector with 160 eV resolutions at 5.9 keV. The measured values were compared with the calculated theoretical values. The obtained values are in good agreement with the calculated values.

Opis:
The results of X-ray diffraction, thermogravimetric and FTIR spectroscopy analyses of mineral composition indicated that the El-Lajjun oil shale is principally composed of calcite, quartz with minor amounts of kaolinite), gypsum, and apatite. The obtained oil shale ash products at 830 °C and 1030 °C are dominated by lime, quartz, anhydrite, portlandite, gehlenite, and amorphous phases. The TGA weight loss curves clearly indicate that it occurred in the temperature range from 310 to 650 °C. The decomposition of oil shale carbonates was detected above 750°C. The functional groups in the organic material of oil shale are dominated by the aliphatic hydrocarbons, the semi-ash of which had diverse structures of polycyclic aromatic hydrocarbons. The most intensive of combustion occurred in the temperature range of 400–750 °C. In this temperature range, about 75 wt.% was accounted for the total mass loss.

Opis:
Medyczne obrazowanie rentgenowskie jest oparte na pomiarze osłabienia wiązki promieniowania przechodzącej przez tkanki pacjenta. Osłabienie wiązki nie jest jednak jedynym efektem oddziaływania promieniowania w tkankach. Oprócz osłabienia obserwujemy rozproszenie (także wsteczne), tworzenie promieniowania charakterystycznego (wymuszona fluorescencja), a nawet zmianę fazy i załamanie fali elektromagnetycznej. Artykuł zawiera krótki przegląd literatury dotyczącej możliwych zastosowań tych zjawisk w obrazowaniu medycznym.
X-ray medical imaging is based on measuring the attenuation of the radiation beam passing through the patient’s tissues. However, beam attenuation is not the only effect of radiation interaction in tissues. In addition to attenuation, we can also observe scattering (including backscattering), creation of characteristic radiation (X-ray fluoerescence), and even phasechange and refraction of the electromagnetic wave. The article contains a brief review of the literature on the possible applications of these phenomena in medical imaging.

The aim of this study was to determine the concentration of Fe, Ni, Cu, Zn and Pb in scalp hair of leukaemia patients and healthy volunteers, using the optimised XRF method. Leukaemia hair samples were classifi ed corresponding to type, growth and age of the participants. The results showed that the studied trace elements (TEs) in both of leukaemia and control groups were positively skewed. In comparison with the control group, lower Fe, Cu, Zn and Pb and higher of Ni medians were found in all studied leukaemia patients. The median rank obtained by Mann–Whitney U-test revealed insignifi cant differences between the leukaemia patients subgroups and the controls. An exact probability (α < 0.05) associated with the U-test showed signifi cant differences between medians in leukaemia patients and controls groups for Pb (lymphatic/control, acute/control), Cu (lymphatic/control, chronic/control), Ni (lymphatic/control, chronic/control) and Fe (chronic/control). Very strong positive and negative correlations (r > 0.70) in the scalp hair of control group were observed between Ni/Fe-Ni, Cu/Fe-Cu, Zn/Fe-Zn, Pb/Fe-Pb, Cu/Ni-Zn/Ni, Cu/Ni-Pb/Ni, Zn/Ni-Pb/Ni, Zn/Fe-Zn/Cu, Pb/Ni-Ni and Ni/Fe-Pb/Ni, whereas only very strong positive ratios in the scalp hair of leukaemia patients group were observed between Ni/Fe-Ni, Cu/Fe-Cu, Zn/Fe-Zn and Pb/Fe-Pb, all correlations were signifi cant at p < 0.05. Other strong and signifi cant correlations were also observed in scalp hair of both groups. Signifi cant differences between grouping of studied TEs in all classifi ed leukaemia groups and controls were found using principal component analysis (PCA). The results of PCA confi rmed that the type and the growth of leukaemia factors were more important in element loading than the age factor.

Opis:
The elemental composition of terrigenous sediments is extremely important for interpreting the depositional conditions of sedimentary basins especially when traditional data are not available or insufficient. For the first time in the published literature, the elemental composition of the Lower Cretaceous Weald Basin (south-east England) is presented via X-ray fluorescence (XRF) and Spectral Gamma-ray (SGR) methods. The concentrations of Zr, Cr, Ni, Rb, and Sr in varying quantities suggest that the sediments may have been sourced from a stable craton while the enriched redox-sensitive elements such as Mo and Co confirm the presence of anoxic and reducing conditions at the sites of deposition. The spectral gamma-ray data show that the sandstone facies are more radioactive than the adjacent mudstone and shale and this trend is consistent with a freshwater origin. The higher quantity of thorium in relation to uranium indicates humid and hot palaeoclimatic conditions at the source areas that favoured intense weathering. The results of these analyses reinforce the importance of the geochemistry of sedimentary rocks as useful tools for understanding the depositional conditions of sedimentary basins.

The elemental sensitivity method for X-ray fluorescence analysis was applied to determine S, Cl, K, Ca, Fe, Cu, Zn, Br, and Rb in the whole blood of leukemia patients and healthy volunteers. Leukemia samples were classified according to type, growth, and age of participants. Student’s t-test results showed that, the mean concentration of the studied elements was significantly lower in leukemia patients than that in controls. Strong mutual correlations (r greather than 0.50) in the whole blood of leukemia patients were observed between S-Ca, K-Fe, K-Ca, Fe-Zn, K-Zn, K-Rb, Fe-Rb, Zn-Rb, S-Cl, S-K, Ca-Fe, Cl-Ca, and Ca-Rb; whereas, S-K, S-Ca, S-Cl, Cl-K, Cl-Ca, Fe-Zn, Zn-Rb, Fe-Rb, K-Fe, and Zn-Br exhibited strong relationships (r greather than 0.50) in the whole blood of controls, all were significant at p less than 0.05. Significant differences between grouping of studied elements in the control group and all classified leukemia groups, except younger age-group, were obtained using principal component analysis. The study indicated appreciably different patterns of element distribution and mutual relationships in the whole blood of leukemia patients in comparison with controls.

Opis:
Mercury concentrations in ash taken from electrostatic precipitations (ESPs) installed in bituminous coal and lignite power plants have been analyzed by the X-ray fluorescence (XRF) method and leaching test supported by detailed coal and ash compositions’ analyses, surface scans and particles size distribution studies. The results showed that mercury was present on the surface of ash particles. Its concentration decreased upon increasing size of ash particles. Leaching tests showed that only small part of mercury was removed with water which suggests the fact that it occurred mostly in the form of insoluble compounds such as Hg, HgO, HgS and Hg2Cl2. There existed ash particles of the diameters from 50 to 60 μm, characterizing by the maximum capability to adsorb mercury and its compounds. The authors suggest that metals like copper and lead formed ash active centers that were preferably occupied by molecules containing atoms of mercury. It was highly possible to expect that content of these elements in ash would have a significant effect on sorption of mercury from combustion gases.

Opis:
During archaeological research of early medieval settlement in Dąbrowa Górnicza - Łosień, a hoard of silver coins and silver smelts was discovered, over 1000 items in total. There was also found a mining shaft and numerous furnaces in the settlement area, confirming its mining and metallurgical character. The settlement development was based on excavating and smelting rich lead ores, containing significant amount of silver. Silver was separated from lead in successive stages with the help of cupellation. The paper presents the analyses of silver smelts and coins coming from the hoard. Optical and scanning microscopy were applied as well as the methods of chemical content analysis by X-Ray Fluorescence (XRF), Scanning Electron Microscopy and Energy Dispersive Spectroscopy in microareas (SEM-EDS), and also phase analysis with the help of X-Ray Diffraction method (XRD). The impurities of the silver clumps testify to the fact that they are semi-products. After refining and modifying the material by adding copper, denars were minted from it. The silver coins belonging the hoard are made from relatively pure material, including a small lead. An insignificant amount of other metallic elements testifies to the good quality of the raw material and efficiency of silver production in the early Middle Ages.

Opis:
Metody radiograficzne pozwalają za pomocą promieniowań X oraz gamma (γ) wykrywać wewnętrzne niezgodności w całej objętości materiału. W zasadzie nie ma ograniczeń co do rodzaju badanych obiektów. Warunkiem jest jedynie dostęp do dwóch stron napromieniowywanego przedmiotu lub konstrukcji. Alternatywą dla analogowych, błonowych technik radiograficznych jest radiografia cyfrowa. O jakości obrazu i dawce pochłoniętej decyduje technologia przetwarzania promieniowania hamowania na sygnał cyfrowy. Postęp w radiografii stymulowany jest głównie przez zastosowania medyczne i przemysłowe. Z nowych rozwiązań mogą korzystać również konserwatorzy dzieł sztuki. Dużą rolę w upowszechnianiu technik jądrowych w identyfikacji i konserwacji obiektów istotnych dla dziedzictwa kulturowego odgrywa Międzynarodowa Agencja Energii Atomowej (MAEA). W artykule omówiono niektóre aspekty zastosowania radiografii w muzealnictwie dyskutowane w trakcie konferencji MAEA zorganizowanej w Narodowym Muzeum Wojny na Malcie.
Radiographic methods make it possible to detect internal and subsurface imperfections in the entire volume of the material using X and gamma rays (γ). In principle, there are no restrictions as to the type of tested objects. The condition is only access to two sides of the irradiated object or structure. An alternative to analog, film radiography techniques is digital radiography. The quality of the image and the absorbed dose are determined by the technology of converting the braking radiation (bremsstrahlung) into a digital signal. Advances in radiography are mainly driven by medical and industrial applications. The new solutions can also be used by art conservators. The International Atomic Energy Agency (IAEA) plays a major role in the dissemination of nuclear techniques in the identification and conservation of objects significant for cultural heritage. The article discusses some aspects of the use of radiography in museology discussed during the IAEA conference organized at the National War Museum in Malta.

This work presents the metallographical observations of the chosen copper objects from the Late Middle Ages. Part of these studies is the analysis of metal relics from the Puck area conducted at the Faculty of Foundry, AGH-UST, in collaboration with the University of Warsaw. Medieval European cities were centers of trade and production of metal artifacts. Also in the Puck area, the manufacturing activities can be confirmed based on the metal findings. The aim of this study was to identify and systematize copper alloys used in the Late Medieval Period, on the basis of historic artifacts from Puck. The chemical composition analysis and microstructure observation were carried out. The research is at the first stage of an experiment of reconstructing the medieval alloys in order to study deeper their properties.

Opis:
Handheld X-ray fluorescence spectrometers with energy dispersion (EDXRF) are increasingly used to determine the chemical composition of rocks for the oil and gas industry. The results of our research allow to create or support the lithological interpretation based on mineralogical models. In the case of quantitative interpretation based on the results of measurements using a handheld XRF device, high accuracy of measurements is required. This paper presents the problems to which attention should be paid when applying the assumed methodology, mainly related to the underestimated percentages for light (main) elements. The tests were carried out on powdered samples of drill cores taken from borehole directed to Rotliegend rocks. The measurements were carried out using Bruker’s XRF S1 TITAN spectrometer. The calibration and correction tests led to the elimination of two factors affecting the inaccuracy of the analyses. The first is the progressive aging of the X-ray tube, which should be checked by conducting systematic measurements of the standard reference material. The second concerns the effect of a change in the density of the sample after grinding, which has a significant impact on light elements (mainly silicon and aluminium), causing a decrease in absolute values in the results of measurements using a handheld XRF device. Due to the type of rock material analysed, the focus was on the calibration of the results of the main elements building the Rotliegend sandstone rock matrix. The paper presents the possibility of calibrating the results directly in the device, which results in obtaining calibrated results after each measurement, as well as calibration of results in an external file. By using external calibration, errors caused by changing the rock matrix can be avoided while ensuring that possibility the results can be recalculated. The resulting calibration coefficients are applicable to the Rotliegend rocks and the XRF spectrometer with current software and GeoChem calibrations provided by Bruker. A change in any of the factors requires re-testing and recalibration of the results. Mineralogical models prepared based on XRF analyses can be used in the future, if those appropriate calibration coefficients are used.

The objective of the present investigation was to study the chemical composition of leaves of Carica papaya belonging to family Caricaceae growing in semi-arid region of Kachchh district, Gujarat, India. The leaves of C. papaya were subjected to Energy Dispersive X-ray Fluorescence (EDXRF) and were analyzed for different mineral composition. As the X-ray Fluorescence is one of the most reliable and accurate, as well as it is also a consistent and non-destructive method for analysis of major and trace elements using a single pressed pellet. During the study it was found that Oxygen, Calcium, Magnessium, Potassium were noted in higher amounts, compared to that of other elements like Silicon, Sulphur, Phosphorus, Chloride, Strontium, Stanous, Aluminium, Cromium and Mangenese, whereas the elements which were not detected in leaves of C. papaya are Vanadium, Titanium, Cobalt and Tantalum.
