秦山核电流出物中锶-90快速测量方法研究

Rapid measurement of strontium-90 in Qinshan Nuclear current emission

用于放射性核素90Sr测量的锶特效固相萃取片技术是最近几年开发的新技术,它的原理是在聚四氟乙烯纤维制成的薄片中嵌入锶特效萃取剂(冠醚)的Si O2颗粒(9um),在片上完成对90Sr的浓集、纯化及测量源的制备。它比传统的放射化学分析法更简便快速。本文主要是应用秦山核电的放射性废液对90Sr快速测量方法进行检验。

The strontium specific solid phase extraction（ SSPE） technique used for the radionuclide 90 Sr measurement is a new technology developed in recent years. Its principle is to embed the Si O2 particles（ 9 um） of the special effective extractant（ crown ether） in the thin film made of polytetrafluoroethylene（ polytetrafluoroethylene） fiber,and complete the concentration, the purity of the 90 Sr and the preparation of the source of the measurement on the sheet. It is simpler and faster than traditional radiochemical analysis. This paper mainly applies the radioactive waste liquid from Qinshan nuclear power to test the rapid measurement method of 90 Sr.
