放射性气体37Ar监测方法与系统发展现状概述

Abstract

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
