Development of k0-INAA standardization method by neutron activation with Am–Be source

The k0-standardization method on the 241Am–Be isotopic neutron source has been studied and developed. In this paper, the characteristics of the neutron spectrum in an isotropic neutron field of 241Am–Be isotopic neutron sources was experimentally determined by dual monitor method using measured cadmium ratios of 197Au(n, γ)198Au and 98Mo(n, γ)99Mo(β−)99mTc reactions. Application of the k0-standardization method for the determination of elemental concentrations such as Al, Mn and Na in cement is carried out as well. The obtained results are in agreement with other analyses. - Highlights: ► Development of k0-INAA standardization method for neutron activation using Am–Be source. ► Efficiency of HPGe detector was determined with cylinder and foil samples. ► Characteristic of neutron spectrum of Am–Be source was measured using dual monitor cadmium ratio method of Au and Mo monitor. ► Analyses of concentration of Al, Na and Mn in cement samples was carried out.
