Introduction: Pyeloureteral junction syndrome is the most common of the congenital obstructive uropathies. Her annual impact is evaluated at 5 for 100,000 in the general population in Senegal. Its frequency ranged from 1 to 10 across 5000 births. Dynamic renal scintigraphy (DRS) with hyperdiuresis testing has two aims: to define the impact of urinary tract obstruction on renal function and to assess the severity of the obstruction and the flow of the urine. Our objective was to evaluate t...

Radon is a naturally occurring radioactive gas produced by uranium decay in soil and rocks, and the dominant source of natural ionizing radiation exposure. Prolonged indoor inhalation of its alpha-emitting progeny is the second leading cause of lung cancer after tobacco smoking. This study provides the assessment of indoor radon concentrations in 25 dwellings across five villages in a mountainous region in northern Pakistan. These villages (Kamra, Thoon, Paija, Bhattian, and Chaffar) are in Kotl...

In this study the radon-222 ( 222Rn) concentrations for the groundwater quality in selected area of Saudi Arabia—AL Qassim is measured beside the physicochemical parameters (pH, total dissolved solids [TDS], and electrical conductivity [EC]), and heavy metal content. Eight groundwater samples were analyzed using advanced techniques, including the RAD7 detector with the RAD-H2O accessory for radon detection, EZ9909SP water quality testing, and inductively coupled plasma mass spectrometr...

We used the MATLAB Program to calculate the mass stopping power and range of alpha particles in biological human body tissues (such as water and the eye lens tissues) at energies between 0.2 and 200 MeV. The Bethe Block formula was used to calculate the mass stopping power, and the simple integration (continuous slowing down approximation) method was used to calculate the alpha particle ranges. Empirical formulae were developed to determine mass-stopping power and ranges of water and eye lens ti...

The mass stopping power and range of alpha particles in biological human body tissues (blood, brain, adipose, and bone) were computed using the MATLAB Program at energies ranging from 0.2 MeV to 200 MeV. The Bethe Block formula was used to compute the mass stopping power. Furthermore, the alpha particle ranges at the tissues were calculated using the simple integration (continuous slowing down approximation) method. The results of mass-stopping power versus energy and range versus energy were gr...

A Yukawa-type potential was used to predict B for the current nuclides using a set of 23 nuclides as the source of the experimental values. The deviation between measurement and prediction was remarkably reduced by a special search on the average distance between nucleons. The best results were obtained for a 2-exponential model. The predictions of B inside and outside the range of A and Z used to do the fitting were carried out by fitting the obtained values of the average distance between nucl...

This article discusses the implications of the Ukrainian military conflict on the safety and security of Zaporizhzhia Nuclear Power Plant (ZNPP). We have used some simplified models to calculate the boiling and boiling-off times of water in the spent fuel pools to estimate the impacts of complete shutdown of cooling systems and the probability of dangerous accidents in storage facilities. Our data confirm that this probability is not negligible, so, this factor of risk should be taken into consi...

The neutron depth profile analysis (NDP) technique can obtain the depth distribution information of 10B, 6Li, 7Be, 22Na and other light core elements near the surface without loss. It is widely used in the influence of Li on the performance of lithium batteries. When using NDP technology to measure lithium concentration in lithium batteries, the distribution of target nuclide concentration with sample surface depth can be obtained by measuring energy spectrum inversion. In this paper, the princ...
