Activation of diet samples by epithermal reactor neutrons is a very sensitive method for the determination of iodine. The method was developed and optimized for its determination. However, it turned out that with the same measurement valid results were also obtained for Br, Cl, K, Na, and P. The procedure involves the irradiation of the sample in a boron nitride (BN) container for 1 min, followed by gamma-counting for 20 min after a decay time of 7-15 min. The necessary sample weight is 0.5 g (dry), and no chemical operations have to be performed. The capacity is 15 samples per working day, and results are available immediately.
超热反应堆中子对饮食样本进行活化分析是测定碘的一种非常灵敏的方法。该方法是为碘的测定而开发并优化的。然而，结果表明，使用相同的测量方法，对于溴、氯、钾、钠和磷也能获得有效的结果。该程序包括将样品置于氮化硼（BN）容器中辐照1分钟，然后在7 - 15分钟的衰变时间后进行20分钟的伽马计数。所需样品重量为0.5克（干重），无需进行化学操作。每个工作日可处理15个样品，结果可立即获得。
