The aim of the present study was extended from obtaining information about the interaction of gamma rays with Makrofol DE 7-2 track detector to introduce the basis that can be used in concerning simple sensor for gamma irradiation and bio-engineering applications. Makrofol polymer samples were irradiated with 1.25 MeV (60)Co gamma radiations at doses ranging from 20 to 1000 kG y. The modificati...

the present study describes the radiation-induced effects on nutritional quality and on anti-nutritional factors of sorghum grain: effects of electron beam (er) and gamma irradiation (gr) at doses of 10, 20 and 30 kgy and infrared irradiation (ir) at 60, 90 and 120 s on the chemical composition, mineral content and bioavailability, in vitro protein and starch digestibility, total phenolic compo...

The present study demonstrates a green process for the synthesis of spherical-shaped and stabilized silver nanoparticles Ag NPs using gamma irradiated conditions. This method has certain advantages over conventional methods since it can manage particle size structure generates totally reduced extremely pure free from by-products or chemical reducing agents. Silver composite (Ag / CM) is prepare...

Dose rates distribution through the 60 Co Gamma Irradiation Facility (GIF) at the Biotechnology and Nuclear Agriculture Research Institute (BNARI) was studied using the Monte Carlo code MCNP5. The MCNP5 code was used to model the GIF structure. The dose rates for selected dwell positions throughout the facility was calculated and analyzed. The absorbed dose rate distribution calculated ranged f...

Male rabbits, aged 4.5 months, were subjected to graded total gamma irradiations of 0.5 Gy, 1.5 Gy, 2.5 Gy and 3.0 Gy with a dose density of 24 Gy/min. The genetic effects in spermatogonia were assessed 3 months later using cytogenetic analysis of chromosomal preparations. The data showed a dose-dependent increase in the frequency of reciprocal translocations, induced in spermatogonia and detec...

The radiobiological effectiveness of 160 MeV protons was measured relative to -Co y-rays, using Chineee hamster cells cultured in o&o. Separate experiments were performed witb cells irradiated in sWpem&m, or attached to plastk tisslre culture flasks. Proton irradiations were performed in the incident plateau of the depth dosepro6Uc~niththeBrPggpenksprendouttocoverlOcls.Inallcrrscstberdstlveblde...

Scintillation light from gamma ray irradiations in liquid xenon is detected by two Hamamatsu R9288 photomultiplier tubes (PMTs) immersed in the liquid. UV light reflector material, PTFE, is used to optimize the light collection efficiency. The detector gives a high light yield of 6 photoelectron per keV (pe/keV), which allows efficient detection of the 122 keV γ-ray line from 57 Co, with a good...

this research was performed to compare electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kilo gray (kgy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (sfm). ionizing radiations of eb and gr had significant effects )p

The present study describes the radiation-induced effects on nutritional quality and on anti-nutritional factors of sorghum grain: effects of electron beam (ER) and gamma irradiation (GR) at doses of 10, 20 and 30 kGy and infrared irradiation (IR) at 60, 90 and 120 s on the chemical composition, mineral content and bioavailability, in vitro protein and starch digestibility, total phenolic compo...
