Prompt gamma-ray activation analysis (PGAA) was applied to well homogenized meteorite samples initially prepared for the wet chemical analysis. By comparing the PGAA data with wet chemical analysis data in literatures, it was confirmed that PGAA can be alternative or even advantageous to wet chemical analysis in terms of the data reliability. Because the same sample can be analyzed by INAA followed by PGAA, data obtained by a combination of PGAA and INAA were proved to enable us to discuss the detailed chemical characteristics of meteorite samples represented by eucritic meteorites (eucrites).

PGAA 与湿化学分析法测定真晶陨石中主要元素含量的比较

快速伽马射线活化分析 (PGAA) 被应用于最初为湿化学分析准备的均质良好的陨石样品。通过将PGAA数据与文献中的湿化学分析数据进行比较，证实PGAA在数据可靠性方面可以替代甚至优于湿化学分析。因为同一样品可以先用INAA再用PGAA进行分析，所以证明了结合PGAA和INAA获得的数据使我们能够讨论以eucritic陨石（eucrites）为代表的陨石样品的详细化学特征。
