将多次γ射线探测与中子活化分析相结合，发展了一种新的痕量元素定量方法。该方法具有灵敏度高、多元素同时分析等特点。根据统计，定量准确度为3-20%。已成功地应用于火成岩样品、长寿命放射性核素129 I和地质样品的分析。将介绍创新脉冲中子源和新探测器系统的未来前景。
A new trace-element quantification method has been developed by combining multiple gamma-ray detection and neutron activation analysis. This method is characterized by high sensitivity and simultaneous analysis for multielements. The quantification accuracy amounts to 3–20% depending on statistics. It has been successfully applied to the analyses of igneous rock samples, long-lived radionuclide, 129I, and geologic samples. Future perspectives for an innovative pulsed neutron source and a new detector system will be presented.
