气载放射性监测仪气体管路外泄漏率测量方法改进

Improved Method of Measurement for Outer Leak

气载放射性监测仪都配备气体取样和输运管路,仪表性能检验包括气体管路的密封性和气体泄漏率试验,在ISO2889-2010中明确规定了气体测量仪取样管路气体泄漏率的技术指标,根据核设施辐射监测系统设计和检验的实践经验,提出了一套测量气体管路泄漏率的实用方法。

Pneumatic pipeline is installed for the airborne radioactivity measurement equipment, air tightness and outer leak rate are essential for the testing of the characteristics, both in the national criteria and ISO standards, an improved practical method is available for the measurement of the outer air leak rate based on the engineering experiences for the equipment acceptance and testing procedure.
