INAA has been used for the determination of Na, Mg, Al, Cl, K, Sc, Cr, Mn, Fe, Co, Cu, Zn, As, Se, Br, Rb, Sr, Mo, and W in grains of rice, wheat, and barley, which were collected from different plant fields in Iraq. Samples and standards were irradiated in the IRT-5000 reactor, at neutron fluxes of 2 x 10(13) cm-2.s-1 and 3.2 x 10(11) cm-2.s-1. Interferences of photopeaks with each other were considered, and reaction interferences were calculated and determined experimentally. Accuracy of our method was assessed by the analysis of IAEA standards Wheat Flour and Bovine liver. A good agreement has been achieved between the present results and recommended values. The precision and detection limit were determined for all elements in all types of grain.
仪器中子活化分析已用于测定从伊拉克不同农田采集的大米、小麦和大麦谷物中的钠、镁、铝、氯、钾、钪、铬、锰、铁、钴、铜、锌、砷、硒、溴、铷、锶、钼和钨。样品和标准品在IRT - 5000反应堆中以2×10(13) cm-2.s-1和3.2×10(11) cm-2.s-1的中子通量进行辐照。考虑了光峰之间的相互干扰，并通过实验计算和确定了反应干扰。通过分析国际原子能机构标准小麦粉和牛肝评估了我们方法的准确性。目前的结果与推荐值之间取得了良好的一致性。测定了所有类型谷物中所有元素的精密度和检测限。
