Designing an Am-Be miniature neutron source
Background: Miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. The most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. In this research, we have surveyed and designed an Am-Be miniature neutron source fabrication. Materials and Methods: This investigation resulted in creation...
متن کاملCharacterization of Am-Be neutron source based PGNAA setup using aqueous solutions of Chlorine and Boron
Background: A 5 Ci 241Am-Be radio isotopic neutron source-based prompt gamma neutron activation analysis (PGNAA) setup was designed for estimation of minimum detectable concentration (MDC) of elements in aqueous solutions. Materials and Methods: Performance variables related to PGNAA setup (source to sample distance, sample to detector distance and volume of water) were optimized experimentally...

متن کاملUtilization of Am-Be Neutron Source in PGNAA Setup Used in Cement Raw Material Analysis
Hundreds of cement factories use online bulk material analyzers to improve their quality control for both raw material and kiln feed, and reduce their variability. The most used technology for online analysis is Prompt Gamma Neutron Activation Analysis (PGNAA), with Cf as the neutron source. Cost and short half-life of the Cf neutron sources are the main problems in cement industry. Therefore, ...
متن کاملThe comparison of four neutron sources for Prompt Gamma Neutron Activation Analysis (PGNAA) in vivo detections of boron
A Prompt Gamma Ray Neutron Activation Analysis (PGNAA) system, incorporating an isotopic neutron source has been simulated using the MCNPX Monte Carlo code. In order to improve the signal to noise ratio different collimators and a filter were placed between the neutron source and the object. The effect of the positioning of the neutron beam and the detector relative to the object has been studi...
