Neutron spectrum and intensity that produced from H218O target bombardment were determined. SRIM and ALICE computer codes were applied to H218O target and its Titanium window for 17 MeV incident proton beam from cyclotron Cyclone30. Using calculated neutron intensity and spectrum as the source, equivalent dose rate at a certain distance from the target was calculated by the MCNP computer code a...
Neutron detection efficiency of superheated drops of Freon-22 for neutrons obtained from a 3 curie Am-Be neutron source has been reported in this paper. Although Freon-22 having lower boiling point than many other similar liquids (e.g.Freon-12, Freon-114, Isobutane) is expected to be more sensitive to neutrons ,it has not been reported so far and therefore this paper constitutes the first repor...
In this study, the neutron and gamma doses in the dry channel and in the internal irradiation site of the Miniature Neutron Source research reactor (MNSR) has been calculated and measured. The MNSR reactor is a light water reactor with a maximum power of 30 kW and equipped with various irradiation facilities, including five irradiated sites, five irradiation sites and a dry channel. The interna...

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...
