Abstract

Channel Bsite2 of Ghana research reactor-1 has been characterized for k₀-INAA application. Cadmium ratio and bare multi-monitor were used to determine flux parameters using 0.1%Au-Al, Fe, and Zr wire as flux monitors. The parameters determined were 18.36±1.91, 0.0479±0.012, 5.12×10¹¹±0.42×10¹¹ncm^-2s^-1, 2.74×10¹⁰±0.14×10¹⁰ncm^-2s^-1, 7.73×10¹⁰±0.16×10¹⁰ncm^-2s^-1 and 16.75±1.58, -0.034±0.0028, 4.28×10¹¹±1.71×10¹¹ncm^-2s^-1, 2.55×10¹⁰±0.15×10¹⁰ncm^-2s^-1 respectively for thermal-to-epithermal flux ratio, alpha, thermal neutron, epithermal neutron and fast neutron flux using cadmium ratio and multi-monitor method accordingly. The k₀-INAA performance assessment based on z-score distributions showed most results within |z| < 2.
