Optical properties of hydrothermally deposited Ni and Co doped nanostructured ZnO thin films as scintillating coatings for beta-particles detection
No full textThe optical properties of ZnO films doped with the Ni and Co transition metals that were hydrothermally deposited on a silicon substrate are discussed. The SEM, EDX, XRD and Raman spectroscopy studies showed that the films deposited have a compact crystalline structure and can be considered as nanostructured polycrystalline ZnO films doped with Ni and Co and designated as ZnO:Ni and ZnO:Co, respectively. Under optical and electronic excitation, the films demonstrated both near-band-edge ultraviolet and visible range luminescence due to crystal lattice defects. The highest intensity of the ultraviolet luminescence with a fast decay was achieved for the ZnO:Ni and ZnO:Co samples deposited in the 0.05 M solutions of Ni or Co nitrate salts. Wide luminescence spectra make the films obtained promising as luminophore or scintillating coatings for the beta-particles detection including structures integrated with silicon circuits, for example, solid state silicon-based radiation counters

Reducing of radiation dose for X-ray using contourlet transform and block thresholding technique
No full textMedical Image Denoising represents one of the fundamental challenges in the field of biological image processing and computer vision. X-Ray imaging is one of the widest used image acquisition technique in hospitals. Image denoising goal is to enhance the original X-Ray image by suppressing noise from a noise-contaminated version of the image. In this paper, a comprehensive survey of the types of noise added in X-Ray examination images was conducted, and to develop a database of five known types of X-Ray examinations in the hospital, three devices were randomly selected and 100 patients included in this survey. The survey results have been compared with the results of the International Atomic Energy Agency (IAEA) and the data have been useful to serve as a national guide or reference. Secondly, a denoising algorithm using Contourlet transform with blocking method was proposed to improve the quality of X-Ray images, which reduces the radiation dose resulting from repeated radiographic attempts to patients and workers

Synthesis and Optical Characterization of Silicon Nanowires via Metal-Simulated Chemical Etching
No full textThis paper presents the findings of a comprehensive study on the characteristics, creation, and optical properties of silicon nanowires (SN) formed through metal-stimulated chemical etching (MSCE) of single-crystal silicon, considering both hole and electronic types of conductivity. Our investigation aims to deepen the understanding of key factors contributing to SN genesis. Notably, a direct correlation has been established between the duration of chemical etching and the resultant silicon nanowire's (SN) length, irrespective of the total etching time. The research encompasses an exploration of various spectral phenomena, including total and specular infrared (IR) reflection, Raman scattering (RS) of light generated by WHs, photoluminescence (PL) spectra, and more. Remarkably, the study reveals a noteworthy linear relationship between the duration of chemical etching and the length of the silicon nanowires. Furthermore, our investigation into diverse spectral phenomena, such as total and specular infrared (IR) reflection, Raman scattering (RS) from light generated by WHs, and photoluminescence (PL) spectra, elucidates intriguing patterns. Specifically, the silicon band in the Raman spectrum demonstrates an increase in size and a migration towards shorter wavelengths with prolonged chemical etching time
Naturally Occurring Radioactive Materials in the Soil of Near Basra Oil Company Fields
No full textThe present study aimed to determine the levels of contamination with Natural Occurring Radioactive Materials NORM in one of the south oil company fields. The external gamma absorbed dose rate Dγ measured in units of µSv/h was caused by gamma rays of Radium 222, Radium 228 (Thorium 232), and Potassium 40, respectively. The largest value is 9.220 µSv/h. It was found that the highest specific activity (concentration) for Radium 226 is 1136 Bq/kg and the lowest is 0.06 and the highest specific activity for Radium 228 is 721 Bq/kg and the lowest is 0.02 Bq/kg. As for Radium 224, its highest specific activity is 631 Bq/kg and the lowest is 0.02 Bq/kg. Radium-228 is higher than that of Radium-224 or Radium-226, as the Radium-224 is from the Uranium-232 series, and the Radium-228 and Radium-224 are from the Thorium-232 series, meaning that the percentage of the daughters of the Thorium chain is lower than the percentage of the daughters of the Thorium chain Uranium, because the half-life of Radium-226 is 1600 years, which is greater than the half-life of Radium-228, which is 5.75 years. A comparison was made between the local results with the results of soil in Amman. Methods of treating pollution with natural radioactive materials in the oil industry were also discussed
Early Diagnosis of Respiratory Disease in Light of COVID-19 Infection and Use of Oxygen Concentrators and CPAP Devices for the Treatment of Respiratory Failure
No full textThe need for early diagnosis of respiratory diseases, especially in the context of the COVID-19 coronavirus infection pandemic, by means of pulse oximetry screening and monitoring has been substantiated. The expediency of using portable pulse oximeters by therapists and general practitioners is shown. The main respiratory diseases accompanied by respiratory failure, which can be promptly detected by pulse oximetry, are chronic obstructive pulmonary disease and obstructive sleep apnea-hypopnea syndrome. Early detection of these diseases is an urgent task due to the low severity of symptoms of these diseases in the early stages and, as a consequence, the prevalence of late diagnosis. Pulse oximetry to detect coronavirus infection COVID-19 deserves special attention, since this infection is also accompanied by respiratory failure. The use of oxygen concentrators and CPAP devices for the treatment of respiratory failure has been argued. The effectiveness of the appointment of long-term oxygen therapy using oxygen concentrators in patients with chronic obstructive pulmonary disease, CPAP therapy using automatic CPAP devices in patients with obstructive sleep apnea-hypopnea syndrome with mandatory pulse oximetry monitoring has been confirmed. A retrospective analysis of 120 cases of treatment of moderate and severe COVID-19 infection complicated by the development of pneumonia was carried out. The efficiency of using oxygen concentrators to supply patients with oxygen at a flow rate of up to 5 l / min has been proven. It was found that no more than 10% of patients needed an oxygen flow at a rate of more than 5 l/min. At the same time, the possibility of using CPAP devices for non-invasive ventilation of the lungs using full-face masks has been shown. The expediency of using oxygen concentrators and CPAP devices for the rehabilitation of patients who have undergone COVID-19 was noted
Gamma Ray Spectrum by Software Methods for Radioactive Waste
No full textThe requirements of NTD (Neglected Tropical Diseases) and technological regulations for the operation of NPP (Nuclear Power Plant) power units (NP-001-97 (OPB-88/97), NP-082-07) define the requirements for monitoring the specific activity of iodine-131 (the amount of iodine) in the NPP primary circuit coolants. The advantages of laboratory control include accuracy of measurement and the radionuclide composition of the primary coolant, measured using high-precision laboratory equipment. Instrumental spectra were obtained for the detection units BDKG-205m with various options for the placement of waste in a container, their composition, mass of waste, average density, and various activity levels of waste. The basic idea behind gamma-ray spectroscopy is to detect and analyze the energy of incident gamma rays. Gamma rays of varying energy and intensity are emitted from radioactive sources. The gamma-ray energy spectrum is produced when gamma rays are detected and examined using a spectroscopy instrument. The initial stage in gamma-ray spectroscopy is to detect gamma rays using a suitable detector. The detector captures and measures the energy of incoming gamma rays. Scintillation detectors, semiconductor detectors, and gas-filled detectors are among the detectors used in gamma-ray spectroscopy. The incoming gamma-ray energy is converted into electrical signals that can be processed and studied by these detectors. The spectroscopic system measures and records the energy of gamma rays when they are detected. The derived energy spectrum depicts the intensity distribution of gamma rays as a function of energy. The spectrum is a visual representation of the different energy levels found in gamma-ray emission
