空气中^(85)Kr的分离与监测技术

Approaches to Separation,Concentration and Monitoring of ^(85)Kr in Air

概述了国际上通用的空气中 85 Kr分离浓集和监测方法。重点比较了各种 85 Kr分离浓集技术的特点 ,表明低温冷冻变温 (或结合变压 )处理方法是目前空气中 85 Kr最好的浓集方式 。

This paper presents an overview of the internationally universal approaches to separation,concentration and monitoring of 85 Kr,focusing on comparison of the characteristics of these methods.The results show that the low temperature refrigeration based(or coupled with pressure variation) method is the best way of concentrating 85 Kr in air,while the liquid scintillation detection is the most sensitive detection mean.
