摘　　要：为满足99Mo-99mTc发生器批量生产的要求,研制了99Mo-99mTc发生器平衡活度测量系统,实现了放射性活度的实时在线测量。本文介绍了该系统的功能特点、系统配置及其性能。实验证明,该系统具有操作简便、测量快速准确等特点,测量的重复性及稳定性均优于0.5%,扩展不确定度<5%。In order to meet the requirement of 99Mo-99mTc generator batch production, the measurement system of 99Mo-99mTc generator equilibrium activities has been developed, which could be measured on line at real-time. Functions and performance of the measurement system are introduced in the paper. Experiments results proved that the system simple operation, fast and accurate measurement. Both the repeatability and stability are less than 0.5%, and expanded uncertainty is less than 5%.
