INSTRUMENTAL NEUTRON ACTIVATION ANALYSIS OF MILK SAMPLES USING THE k0-STANDARDIZATION METHOD AT ES-SALAM RESEARCH REACTOR

In recent years, the k 0 -NAA has been applied and developed at Es-Salam research reactor (Algeria). This paper focuses on the application of the k 0 method of instrumental neutron activation analysis in Nutritional and Health-Related Environmental field. Three kinds of powder milk were analyzed using k 0 -NAA method. Concentrations of six elements Br, Ca, K, Na, Rb and Zn have been determined by long irradiation time with a thermal and epithermal flux of 4.7.10 12 n.cm ―2 .s ―1 and 2.29.10 11 n.cm ―2 .s ―1 , respectively. The reactor neutron spectrum and detection efficiency calibration parameters such as α, f and e p have been used for the calculation of elemental concentrations. The accuracy of the measurements was evaluated by analyzing two SRMs Whey powder AIEA-155 and Milk powder AIEA-153. The analysis results showed that the deviations between experimental and certified values were mostly less than 10%.
