The newly installed multiple prompt gamma-ray analysis (MPGA) system at the Japan Atomic Energy Agency (JAEA) was characterized for nondestructive multi-element analysis of geological and cosmochemical samples. Analysis of the hydrogenous meteorite Orgueil by both MPGA and PGA implies that MPGA can be used for elemental determination with sufficient accuracy. For some elements which cannot be determined by conventional PGA due to the spectral interference or lower sensitivity, it was shown that they could be determined by MPGA.
日本原子能机构（JAEA）新安装的多脉冲伽马射线分析（MPGA）系统用于对地质和宇宙化学样品进行无损多元素分析。通过MPGA和PGA对含氢陨石奥盖尔进行分析表明，MPGA可用于足够精确的元素测定。对于一些由于光谱干扰或灵敏度较低而无法通过传统PGA测定的元素，结果表明它们可以通过MPGA来测定。
