introduction bnct is an effective method to destroy brain tumoral cells while sparing the healthy tissues. the recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. in this paper, it is indicated that using d-t neutron source and optimizing of beam shaping assembly (bsa) leads to treating brain tumors in a reasonable time where all iaea ...

in this research, cobalt and nickel sulfide nanoparticles (nps) were grown on almcm-41 matrix by using ion exchange method. the prepared samples were irradiated by thermalized neutron that emitted from am-be source up to fluencies (7.9+e9n/cm2). after that, x-ray diffraction (xrd), uv-vis spectroscopy, fourier transform infrared (ftir), scanning electron microscopy (sem) and transmission electr...

Background: Several landmine detection methods, based on nuclear techniques, have been suggested up to now. Neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are the nuclear methods used for landmine detection. In this paper an optimized (safe and effective) moderating structure using an 241Am-Be neutron source for detecting landmines has been invest...

Abstract Core conversion requires some evaluation of the reactor safety. Changes to reactivity worth, shutdown margin, power density and material properties are crucial proper functioning reactor. The focus this article is study neutron flux distribution in core radiation damage on candidate clads. Ghana Research Reactor-1 (GHARR-1) operates at maximum 30 kW order attain a 1.0× 10 12 n·cm –2 ·s...

Introduction BNCT is an effective method to destroy brain tumoral cells while sparing the healthy tissues. The recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. In this paper, it is indicated that using D-T neutron source and optimizing of Beam Shaping Assembly (BSA) leads to treating brain tumors in a reasonable time where all IAEA ...

Introduction: Neutrons have many applications in various fields, such as medicine. The important application of neutron in medical science is in Boron Neutron Capture Therapy (BNCT). Because of this, determination of neutron dose and flux is critical for the health maintaining of workers and patients exposed to this beam. The neutron radioisotope sources produce gamma rays in ...

Nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. The nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. Some samples of Breast muscle, Femora muscle, Heart, Gizzard, Liver, Skin, Spleen, Lung, Kidney and Cloacal feces were collected randomly in slaughter...
