    ABSTRACT: High-order perturbation formulas for a 3d9 ion in rhombically elongated octahedral was applied to calculate the electron paramagnetic resonance (EPR) parameters (the g factors, gi, and the hyperfine structure constants Ai, i = x, y, z) of the rhombic Cu2+ center in CoNH4PO4·6H2O. In the calculations, the required crystal-field parameters are estimated from the superposition model which enables correlation of the crystal-field parameters and hence the EPR parameters with the local structure of the rhombic Cu2+ center. Based on the calculations, the ligand octahedral (i.e. [Cu(H2O)6]2+ cluster) are found to experience the local bond length variations ΔZ (≈0.213 Å) and δr (≈0.132 Å) along axial and perpendicular directions due to the Jahn–Teller effect. Theoretical EPR parameters based on the above local structure are in good agreement with the observed values; the results are discussed.

    ABSTRACT: The current work investigated the effect of the Portland cement mixed with different percentages of water and ilmenite ore on the attenuation of gamma radiation as shielding blocks. Different concentrations of ilmenite from 5% up to 20% with different grain size were mixed with cement. The properties of the investigated blocks, as compressive strength, wet and dry density, absorption and porosity percentages, were studied. The thermal stability of the studied samples and their X-ray diffraction (XRD) patterns were examined through thermogravimetric analysis and XRD respectively. In addition, the attenuation coefficients of the considered samples for gamma radiation were performed using gamma ray spectrometer. The results revealed that, the maximum linear attenuation coefficient (µ) and minimum transmission fraction were performed for cement mixed with 10% of ilmenite and with the size range 106–250 µm.

    ABSTRACT: Potassium hydrogenselenate KHSeO4 single crystals were successfully grown by the solution growth technique. The structure of the grown crystals was confirmed by XRD diffraction spectrum to be the structure of the desired KHSeO4 single crystal. The crystals were irradiated by different doses of γ-irradiation in the range 0.4–2.4 kGy and the optical absorption spectra were recorded along the a-, b- and c-axes. The optical inter-band transitions were of the indirect allowed ones and the optical energy gap Eg was determined along the three crystallographic directions. The effect of the irradiation on the optical energy gap is reported along the principle crystallographic directions. Urbach rule suggested the formation of Urbach tail and the effect of irradiation on this band tail is reported. These observations are attributed to the radiation-induced defects on the bulk crystal.

    ABSTRACT: In this study, electron paramagnetic resonance of γ-irradiated single crystals of N-Trifluoroacetyl-α-amino isobutyric acid (F3Ac-Aib-OH) was investigated at room temperature and analyzed for different orientations of the crystal in the magnetic field. The paramagnetic species in N-Trifluoroacetyl-α-aminoisobutyric acid was attributed to the ĊF2-R radical (R= CONHC(CH3)COOH). Hyperfine coupling constants and g value were also determined. In addition, the single crystal of F3Ac-Aib-OH was UV-irradiated and paramagnetic species formed was studied at room temperature. The effects of gamma irradiation on fluoroamino acid and stability were discussed.

    ABSTRACT: Conductive polypyrrole was synthesized with hydrogen peroxide (H2O2) as the oxidant. To promote the polymerization of pyrrole, UV radiation was employed. The effects of UV radiation on the preparation of polypyrrole were investigated. The polymerization of pyrrole was conducted with the H2O2 concentration in the range of 0.12–0.96 M and the H2SO4 concentration in the range of 6.8×10−4–0.19 M. The structure characterization indicated that the product polypyrrole was overoxidized partly depending on the concentrations of H2SO4 and H2O2. The increase in H2O2 concentration led to a slight increase in the oxidation and overoxidation of polypyrrole, simultaneously. However, the increase in H2SO4 concentration effectively suppressed the overoxidation of polypyrrole. The morphology, conductivity and thermal stability of the products were also characterized.

    ABSTRACT: Hexagonal YPO4 phosphors doped with Eu3+/Dy3+ and co-doped with Ce3+ were synthesized by a hydrothermal route assisted using lauric acid as a capping agent. The prepared phosphors were characterized by transmission electron microscopy, infrared spectroscopy, powder X-ray diffraction and photoluminescence spectra. YPO4: Eu3+ gives two red emission peaks at 587 and 610 nm corresponding to 5D0→7F1 and 5D0→7F2 transitions, respectively. YPO4: Dy3+ exhibits two emission peaks at 485 nm (blue) and 575 nm (yellow) corresponding to 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions, respectively. Ce3+ ions enhanced the emission intensity as a co-dopant in both phosphors. Moreover, the effect of γ-radiation in the dose range 5–300 kGy on the photoluminescence behaviour of YPO4:Eu3+,Ce3+ and YPO4:Dy3+,Ce3+ was also investigated. Quenching of emission intensity, after irradiation at 5 and 300 kGy, was observed in both the phosphors due to loss of excess energy through a non-radiative relaxation process.

    ABSTRACT: The purpose of this study was to measure the radiation exposure to operator and patient during cardiac electrophysiology study, radiofrequency catheter ablation and cardiac device implantation procedures and to calculate the allowable number of cases per year. We carried out 9 electrophysiology studies, 40 radiofrequency catheter ablation and 11 cardiac device implantation procedures. To measure occupational radiation dose and dose–area product (DAP), 13 photoluminescence glass dosimeters were placed at eyes (inside and outside lead glass), thyroids (inside and outside thyroid collar), chest (inside and outside lead apron), wrists, genital of the operator (inside lead apron), and 6 of photoluminescence glass dosimeters were placed at eyes, thyroids, chest and genital of the patient. Exposure time and DAP values were 11.7 ± 11.8 min and 23.2 ± 26.2 Gy cm2 for electrophysiology study; 36.5 ± 42.1 min and 822.4 ± 125.5 Gy cm2 for radiofrequency catheter ablation; 16.2 ± 9.3 min and 27.8 ± 16.5 Gy cm2 for cardiac device implantation procedure, prospectively. 4591 electrophysiology studies can be conducted within the occupational exposure limit for the eyes (150 mSv), and 658-electrophysiology studies with radiofrequency catheter ablation can be carried out within the occupational exposure limit for the hands (500 mSv). 1654 cardiac device implantation procedure can be conducted within the occupational exposure limit for the eyes (150 mSv). The amounts of the operator and patient's radiation exposure were comparatively small. So, electrophysiology study, radio frequency catheter ablation and cardiac device implantation procedures are safe when performed with modern equipment and optimized protective radiation protect equipment.

    ABSTRACT: Purpose: The purpose of this study was to assess the possibility of measuring radiation dose based on primary color chrominance in chemical solutions. Methods: We used an aqueous solution with different concentrations of Alphaurine A and Tracid Brilliant Red B. This was irradiated by 1.5–13.5 kGy 60Co γ radiation. Data were collected by an instrument that can detect information on the three primary colors. Data were analyzed and manipulated for each experiment. Results and conclusions: The result shows that three primary colors chrominance in the aqueous solutions change with different doses of 60Co γ-rays and different concentrations of Alphaurine A and Tracid Brilliant Red B. For Alphaurine A, the red chrominance is gradually reduced as a function of radiation dose. The blue chrominance gradually increases concurrently. The red and green chrominance changes obviously and inversely, but the green chrominance changes little. In Tracid Brilliant Red B solution, the red chrominance gradually decreases as the radiation dose increases. The green chrominance gradually increases concurrently. The red and green chrominance changes are obvious and inverted. The blue chrominance changes little. Our experiments demonstrate that radiation dose can be studied based on three primary colors chrominance. This may be a new tool to measure the radiation dose.

    ABSTRACT: The purpose of this study is to determine the changes in the rectum area during treatment and to identify the rectum area within the given field of view in order to reproduce the same pose as that presented during therapy planning to properly deliver the planned dose to the prostate. We obtained digitally reconstructed radiographs after planning treatment for 30 patients out of all patients who had been subjected to proton prostate cancer therapy from August 2012 to November 2014 at this hospital. We then obtained an image using a digital imaging positioning system (DIPS) on the first day of treatment. When planning the digitally reconstructed radiograph treatment, we determined the change in size of the rectum between the actual treatment and treatment planning by measuring the cross section of the rectum and the cross section on the image from the DIPS. The results indicated that the rectum area in the digitally reconstructed radiograph taken during treatment planning and the rectum area obtained from the DIPS image during treatment were different. As a consequence, when region targeted for proton treatment of prostate cancer does not maintain a constant volume, the position of the prostate does not receive an adequate dose due to such changes. Therefore, the results of this study will be useful to determine the corresponding volume during a prostate treatment plan.

    ABSTRACT: The optical absorption spectra, microstructure and electronic spin resonance parameters (electronic spin resonance (ESR) g factor) for Ni2+ ions at octahedral centers of nickel ferrite nanoparticles are calculated from the two-spin-orbit-parameter model. The effect of spin-orbital coupling of the central metal 3d(8) ions and ligand oxygen ions has been taken into account in the full energy matrix and ESR g formula. The calculated results are in good agreement with the observed values. In addition, the microstructures of Ni2+ ions at octahedral centers in NiFe2O4 are reasonably determined from the calculations.

    ABSTRACT: Characterization of helium-implanted Fe–(2.5–12.5)at% Cr alloys with the flux of 7 × 10–6 dpa/s at a temperature of 343 K has been performed by means of cluster dynamics simulations. We have suggested a model for simulating an Fe–C–Cr system under helium implantation based on a selection of the latest data from atomistic studies and available experiments. Kinetics of carbon-vacancy and helium-vacancy complexes has been studied. Only one parameter is used to guarantee the best reproduction possible of experimental positron annihilation lifetime spectroscopy data for Fe–Cr alloys on dependences of vacancy cluster size on chromium content and irradiation dose via fitting. This is an effective binding energy of self-interstitial atoms to dislocation loops decorated by chromium atoms. It has a “snaky” dependence of chromium content with a minimum of about 9%Cr.

    ABSTRACT: The axial zero-field splitting parameter D for Fe3+ at Ge4+ site of ZnGeP2 chalcopyrite semiconductor is calculated using the method based on the dominant spin–orbit coupling mechanism. In the calculation, the impurity-induced local tilting angle (Formula presented.) of anion tetrahedron, which is much larger than the corresponding tilting angle (Formula presented.) in the host ZnGeP2 crystal, is applied. The results indicate the negative sign of D, whereas the magnitude of D is explained reasonably, and the large tilting angle (Formula presented.) is further confirmed for Fe3+ in ZnGeP2 crystal.

    ABSTRACT: Free electron gas is present in every gas, whether it is of atomic or molecular structure. Since the Maxwell spectrum type is the consequence of only thermal motion of constitutive gas particles; therefore, the presence of electric field leads to change the spectrum of charged particles due to their directed motion. However, it has been shown that in the case of occurrence only of elastic interactions between electrons and neutral gas particles (a condition that has been met in the case of weakly ionized noble gases of a relatively huge volume) the deviation of the gas spectrum of free electrons in the electric field from the Maxwell type is negligible. In such a case, the gas spectrum of free electrons is either of Maxwell type (if the frequency collision value is energy-independent) or of Druyvesteyn type (if the mean free electron path value is energy-independent). The Maxwell and Druyvesteyn distribution types are very similar. The only noticeable difference is that the tail of the Maxwell distribution decreases with the energy exponent to the first degree of energy, and the tail of Druyvesteyn distribution with the energy exponent to the second degree of energy. The aim of this paper is to determine whether the gas spectrum of free electrons in weakly ionized noble gases at small values of the product pd (pressure and inter-electrode distance) follows either the Maxwell's or Druyvesteyn's type, as well as to determine the dependence of spectrum parameters on the product pd. It has been established that better results are obtained on the assumption that the mean value of collision frequency is energy-independent.

    ABSTRACT: This work is devoted to the calculation of concentration of radiation displacement defects (RDDs, i.e. atoms, cations or anions displaced from positions in lattice and their associated vacancies) in YVO4 and PbMoO4 crystals as a function of particle energy (electrons and neutrons). Energy dependencies of RDD concentrations are discussed in comparison with results of other complex oxide crystals. The obtained results show that the case of electron irradiation the radiation hardness of YVO4 and PbMoO4 is higher than for other oxide crystals.

    ABSTRACT: The radiation sensing field effect transistor (RadFET) with SiO2 gate oxide has been commonly used as a device component or dosimetry system in the radiation applications such as space research, radiotherapy, and high-energy physics experiments. However, alternative gate oxides and more suitable packaging materials are still demanded for these dosimeters. HfO2 is one of the most attractive gate oxide materials that are currently under investigation by many researchers. In this study, Monte Carlo simulations of the average deposited energy in RadFET dosimetry systems with different package lid materials for point electron and photon sources were performed with the aim of evaluating the effects of package lids on the sensitivity of the RadFET by using HfO2 as a gate dielectric material. The RadFET geometry was defined in a PENGEOM package and electron-photon transport was simulated by a PENELOPE code. The relatively higher average deposited energies in the sensitive region (HfO2 layer) for electron energies of 250 keV-20 MeV were obtained from the RadFET with the Al2O3 package lid despite of some deviations from the general tendency. For the photon energies of 20-100 keV, the average amount of energy deposited in RadFET with Al2O3 package was higher compared with the other capped devices. The average deposited energy in the sensitive region was quite close to each other at 200 keV for both capped and uncapped devices. The difference in the average deposited energy of the RadFET with different package lid materials was not high for photon energies of 200-1200 keV. The increase in the average deposited energy in the HfO2 layer of the RadFET with Ta package lid was higher compared with the other device configurations above 3 MeV.
