摘要

概述了国际放射性核素监测系统中对放射性核素数据在测量过程的安全认证的要求，在推导并模拟铀、针系衰变链中的相应子体和７Ｂｅ等核素从取样至测量过程中放射性活度变化规律以及它们比值的基础上，建立样品取样测量运行及认证模式。在计算机拟合的基础上给出了９７Ｚｒ、１３７Ｃｓ、１４０Ｂａ等与ＣＴＢＴ监测系统要求相关的裂变产物核素的最低检测限度。

Abstract

The radionuclide monitoring data shall follow the safety and verification criteria based on the demand from international Radionuclide Monitoring Station by Comprehensive Test Ban Treaty. It was suggested that the activity and their ratio of

T1 and some other radionuclides could be used for data verification criteria in aerosol sample collection. After using computer simulation

the minimum detectable concentration was given by different measuring time and different sampling flow rate.
