摘要
小密封g放射源活度在线测量系统是以计算机为中心的放射性测控设备。该系统可测60Co等g核素和不同规格的放射源,实时在线自动采集、记录和计算空气比释动能率和放射性活度,显示、打印输出测量结果和存储归档等功能。系统测量范围宽、稳定性好,对60Co源等效活度测量结果扩展不确定度<5%。本文介绍了系统的设计特点、组成和性能。运行实践证明,该系统不仅大大提高了放射性活度测量效率,而且提高了测量的准确性和操作的可靠性与安全性。
The system is a computer-based on-line apparatus for measuring gamma activities of sealed sources. Various gamma nuclides and different kinds of sources can be assayed automatically. Real-time and on-line data acquisition of air kerma rates and activities can be accomplished in this system. Meanwhile, the measured results can be displayed, printed and saved automatically. Its expanded uncertainty for measuring equivalent activity of 60Co source is less than 5% with wide range and good stability. This paper discusses the design features of the system, the general construction, and the specifications. It is proved in practice that the measuring efficiency and accuracy is improved, so is the reliability and safety of measuring operation.
