Radioisotope scanning is very important in evaluation, diagnosis and proper treatment of urinary tract infection (UTI) and vesicoureteral reflux (VUR) because of high sensitivity of this technique and less radiation dose delivered to the patients. This is a descriptive cross-sectional study to determine the frequency VUR in a group of children aged 28 days to 14 years referred to our depa...

A novel multi-source energy harvester based on solar and radioisotope energy sources is designed and simulated in this work. We established the calculation formulas for the short-circuit current and open-circuit voltage, and then studied and analyzed the optimization thickness of the semiconductor, doping concentration, and junction depth with simulation of the transport process of β particles ...

THE left-to-right shunts found in small atrial or ventricular septal defects or in patent ductus arteriosus are easily demonstrated during cardiac catheterization by both rightand left-sided approaches.' Efforts to evaluate shunting due to these defects without cardiac catheterization have depended on measurements of the cardiac output curves obtained by various external counting technics.Y Bec...

RTIFICIAL A radioactive isotopes have been wideIy utiIized in cIinica1 investigations for nearIy two decades. Yet of the more than ninety artificiaIIy produced radioisotopes presentIy available, onIy tweIve have been found usefu1 in the treatment of human iIIness. Of these only four (I-I 3 I, P-32, Au198 and Co-60) are now being cIinicaIIy utiIized in the treatment of diseases of the chest, pri...

In this paper, the feasibility of using an X-ray tube instead radioisotope sources for measuring volume fractions gas, oil, and water in two typical flow regimes three-phase flows, namely, annular stratified, is evaluated. This study’s proposed detection system composed tube, a 1 inch × NaI detector, one Pyrex-glass pipe to model different regimes, stratified. Group method data handling (GMDH),...
