A radiochemical group separation using APDC extraction was applied to the neutron activation analysis of normal and cadmium injected rat liver. In order to optimize determinations of induced radionuclides with various half lives, the gamma-ray spectra were obtained after various decay times. Eight elements, Cd, Co, Cu, Fe, Mn, Mo, Se and Zn, were determined from rat liver samples within 12 day ...

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...

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 ...

Activation of lamina propria (LP) T cells via the CD2 pathway enhances IFN-gamma (IFN-gamma) secretion with further enhancement after CD28 coligation. The molecular mechanisms regulating IFN-gamma expression in LP T cells remain unknown. Previous studies in PBL and T cell lines identified cis- and trans-regulatory elements in TCR-mediated expression of IFN-gamma. This study examines CD2 and PMA...

Abstract The analysis workflow of Prompt gamma activation (PGAA) at the Budapest Neutron Centre’s PGAA and NIPS-NORMA facilities, MLZ FRM II station, other centers worldwide relied on use Hypermet-PC spectrometry software ProSpeRo concentration calculation Excel macro. sustained interest our user community amid reduced availability multiple large-scale neutron sources called for more efficient ...

The measurement facility QUANTOM is being developed for the material analysis of radioactive waste packed up in 200-L drums. enables a spatially resolved elemental based on prompt gamma neutron activation analysis. evaluation spectra relies calculation partial (n,?) cross sections. Hereby, flux spectrum enters as parameter, which needs to be simulated full three-dimensional geometry facility. T...

The neutron activation of shielding materials and the generated decay gamma radiation are well-known issues in terms occupational exposure. Though trace elements concretes can be dominant sources produced activity such cases, their concentrations often missing from input data shielding-related Monte Carlo simulations. For this reason, three concrete types were studied, that considered European ...
