background: several landmine detection methods, based on nuclear techniques, have been suggested during the recent years. neutron energy moderation, neutron-induced gamma emission, neutron and gamma attenuation, and fast neutron backscattering are nuclear-based methods used for landmine detection. the aim of this study is to use backscattered neutron for landmine detection. materials and method...

Polarized and unpolarized neutron scattering have been used to determine the effect of superconductivity on the magnetic excitation spectra of YBa 2Cu 3O 6.5 sTc ­ 52 Kd and YBa 2Cu 3O 6.7 sTc ­ 67 Kd. Pronounced enhancements of the spectral weight centered around 25 and 33 meV, respectively, are observed below Tc in both crystals, compensated predominantly by a loss of spectral weight at highe...

The petrophysical analysis is significant to determine the parameters controlling production wells and reservoir quality. In this study, Using Interactive petrophysics software analyze of five penetrated Zubair in Abu-Amood field evaluate a search for hydrocarbon zones. available logs data such as density, sonic, gamma ray, SP, neutron, resistivity AAm-1, AAm-2, AAm-3, AAm-4, AAm-5 were used pr...

Radiation detection systems for security applications are often equipped with neutron sensors and required to promptly respond an alarm if the flux exceeds background level. As ambient is essentially caused by cosmic radiation, this could be evaluated assessing rate of muons crossing gamma-ray detector which comprised in such anyway. A study performed a commercial Backpack Detection System (BRD...

background: boron neutron capture therapy (bnct) is a very promising treatment for patients suffering gliobastoma multiforme, an aggressive type of brain cancer, where conventional radiation therapies fail. thermal neutrons are suitable for the direct treatment of cancers which are located at near-tissue-surface deep-seated tumors need harder, epithermal neutron energy spectra. materials and me...

Background: The aim of this work was to establish how well gel dosimeters performed, as substitutes for brain tissue compared with standard phantom materials such as water, polymethyl-methacrylate (or PMMA), A150 plastic and TE- liquid phantom material for dosimetry of neutron beams in boron neutron capture therapy. Materials and Methods: Thermal neutron fluence, photon dose and epithermal neu...
