摘要

37Ar是地下核爆确定的、明确的指示剂

目前已经被CTBTO确定为现场视察的核查核素。中国工程物理研究院核物理与化学研究所研制了适合现场视察的37Ar探测系统--移动式37Ar快速探测系统（Movable37Ar Rapid Detection System

MARDS）

该系统采用LLC方法（Low Level Decay Counting）测量37Ar的活度。目前国际上尚无37Ar活度测量的标准装置

因此开展37Ar活度比对测量是一项很有必要的工作。本文介绍了我所（中国工程物理研究院核物理与化学研究所

INPC）与瑞士伯尔尼大学大气与环境物理研究所（KUP）开展的37Ar活度比对测量工作。比对测量的结果说明MARDS测量37Ar活度的方法和结果有很高的可信度

为MARDS系统应用于现场视察提供了技术支持。

Abstract

As a definitive and unambiguous indicator of a nuclear underground explosion

the noble gas of 37Ar is an important nuclide for on-site inspections under the CTBTO (Comprehensive Nuclear-Test-Ban Treaty Organization). The Institute of Nuclear Physics and Chemistry has developed the movable 37Ar rapid detection system (MARDS) for on-site inspections

in which low level decay counting method is employed for 37Ar activity measurement. Because no stand is available for 37Ar activity measurement

comparison of the 37Ar activity measurement is necessary. In this paper

comparison measurement between INPC and Division of Climate and Environmental Physics

Physics Institute

University of Berne (KUP) is reported. The results show that the method used in MARDS is of great reliability in 37Ar activity measurement. This work can enhance the trust of CTBTO for MARDS and support the potential application of MARDS in on-site inspections.
