Development of k0-INAA standardization method by neutron activation with Am-Be source.
The k(0)-standardization method on the (241)Am-Be isotopic neutron source has been studied and developed. In this paper, the characteristics of the neutron spectrum in an isotropic neutron field of (241)Am-Be isotopic neutron sources was experimentally determined by dual monitor method using measured cadmium ratios of (197)Au(n, γ)(198)Au and (98)Mo(n, γ)(99)Mo(β(-))(99m)Tc reactions. Applicati...
متن کاملDesigning 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 کاملDIRECT MEASUREMENT OF ko FOR MONITOR NEUTRON ACTIVATION ANALYSIS
This paper inlroduces the thermal column or the cold neutron guide beam of the 20 MW NBSR at the National Institute of Standards and Technology as a direct k o measurement facility. Measurement of k o at this facility not only produces accurate values, but avoids the additional correction factors needed in other measurement methods. The ko of Sb, Ag and Cr with respect to Sc as monitor have bee...

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...
