摘要/Abstract

摘要： ³⁷Ar属于地下核爆炸特征活化产物,是全面禁止核试验条约组织 (CTBTO)规定的核爆试验现场视察的核查核素,因此对采集的³⁷Ar气体活度浓度进行精准的现场或实验室测量尤为关键。对³⁷Ar的特性、取样纯化技术与活度测量方法进行搜集整理,归纳了国内外现场或实验室测量的先进装置与技术现状,为³⁷Ar活度浓度相关监测等应用领域提供技术支撑。

关键词: ³⁷Ar, 活度浓度, 正比计数器, 现场监测, 实验室测量

Abstract: ³⁷Ar is a characteristic activation product of underground nuclear explosion, and is a verification nuclide of on-site inspection stipulated by the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO). Therefore, accurate field measurement or laboratory measurement of the collected activity concentration of ³⁷Ar are particularly critical. This paper collects and analyzes the characteristics, sampling and purification technology and ³⁷Ar activity measurement methods, summarizes the advanced device and technology status of field or laboratory measurement in the world, with the aim to provide technical support for ³⁷Ar activity concentration-related monitoring and other application fields.

Key words: ³⁷Ar, activity concentration, proportional counter, on-site monitoring, laboratory measurement
