【摘要】 在放射性污染环境治理、长寿命核素核数据测量、高放废物地质处置安全评价、地球成因研究等方面均涉及到长寿命痕量核素的分离、纯化与测试。长寿命痕量核素的分离测试已成为放射化学研究的重要分支,日益引起业界的高度关注。本文系统分析介绍了长寿命痕量核素测试过程中的前处理方法、分离纯化方法以及分析测试方法等研究进展,并就相关基础问题进行了探讨,提出今后研究重点和建议。更多还原

【Abstract】 Ultratrace amounts of long-lived radionuclides are critical nuclides for control of radioactive pollution, data measurement, geological disposal, and origin of the earth studies. The separation and measurement of these nuclides have become an important branch of radiochemistry, which attracts more and more attention in the industry. This paper systematically analyzes the progress on the research of pretreatment, radiochemical separation and purification, as well as the measurement methods. Meanwhile, some interesting technical problems are discussed. At last some suggestions and the key future research directions are given.更多还原
