保障措置にかかわる環境試料分析では、おもに極微量核物質(ウランやプルトニウム)の同位体比を測定する。その際要求される国際標準レベルの極微量分析におけるQA/QC活動と測定の不確かさ評価について、高度環境分析研究棟(CLEAR)で実施している保障措置環境試料に含まれる極微量核物質(ウランやプルトニウム)の同位体比分析を例に現状と課題を紹介する。

In the analysis of IAEA safeguards environmental samples, isotope ratios of ultra-trace amounts of uranium and plutonium in samples taken from nuclear facilities are determined to detect undeclared nuclear materials and activities. In order to keep and enhance the reliability of the measurement results, validation of analytical methods and estimation of measurement uncertainty in such ultra-trace analysis should be properly done in accordance with worldwide standards. In this paper, the current activities on achievement of QA/QC (quality assurance and quality control) and estimation of measurement uncertainty in the ultra-trace analysis at a clean chemistry laboratory (CLEAR) of JAEA are reported.
