background: this cross sectional study was conducted to evaluate the effect of &gamma-rays; and electron-beam irradiation with a commercial toxin binder-milbond-tx on the performance, feed components, and meat quality of japanese quails challenged with aflatoxin b1. methods: overall, 168 one-d-old chicks (japanese quails) were allocated to eight treatments with three replicates based on a compl...
Background; Gold nanoparticles (GNPs) play an important role in medical, health and environmental applications. All kinds of microorganisms were found to be able to synthesize GNPs. The optimization of laboratory conditions for achieving more economical benefits of mass production has been studied widely. Methods;This study assesses the enhancing effect of low-level X-rays on the biosynthesis ...
We briefly review the fundamentals of nuclear gamma-ray line astronomy (radioactive astronomy), focusing on its role to decipher the intimate physics of supernovae, either immediatly (via 56 Co) or after a time delay (via 44 T i). All kinds of super-novae can be in principle tested through their radioactivities and their associated gamma-ray lines. Dedicated to the spectroscopy and imaging of c...
OBJECTIVE The optimization of medical exposure is one of the major issues regarding radiation protection in the world, and The International Committee of Radiological Protection and the International Atomic Energy Agency recommend establishing diagnostic reference levels (DRLs) as tools for dose optimization. Therefore, the development of DRLs based on the latest survey has been required for nu...
in order to improve the performance of a newly developed radiochromic film, gic-79, somedosimetric characteristics of this film have been studied based on relevant standard practice. the presentstudy describes some parameters that may affect the dosimeter response before, during, and after irradiation. the effect of absorbed dose rate on dosimeter response was determined by irradiating dosimete...
background: currently available radioprotectors are poorly tolerated in man and the general use of aminothiols is compromised by their side effects. this study was carried out to test and compare the radioprotective potential of cimetidine and famotidine against lethally gamma irradiated nmri mice. materials and methods: adult male nmri mice in groups of 10 were exposed to various doses of gamm...
The Nubian sandstone aquifer's hydrogeophysical and natural radioactivity parameters at the Northwestern part of El Ain village, Sharq Oweinat, Southwestern desert, Egypt are resolved using geophysical well logging techniques. study aims to monitor phenomenon appearing an unusual high gamma-ray a zone resistivity record. A nest logs is collected assess how widespread. Results correlated clarifi...
