目的研制一套事故后应急环境监测谱仪,具有宽量程、防护等级高、自带无线电传输功能及电池,并可识别人工核素及其剂量率等特点,探测器可在事故后快速在核设施周围组成监测网络。方法通过模块化、专业化、可扩展性等设计理念,依托可靠的质量管理体系,采用成熟的配件,项目成功完成了设计目标。结果研制完成的探测器在周围剂量当量率10 n Sv/h~150μSv/h之间采用Na I(Tl)进行测量,并进行核素识别,在10μSv/h~3 Sv/h之间采用GM管进行测量,通过具有3 G和RF冗余设计的无线传输模块将监测数据发回数据处理中心进行处理及展示。结论研制完成的探测器完成能满足事故后应急监测的需求。
Objective To develop a post-accident emergency environmental monitoring spectrometer with wide range, high protection level, self-contained radio transmission function and battery, and can identify the characteristics of artificial radionuclide and its dose rate, etc. The detector can rapidly detect nuclear after an accident Surrounding facilities form a monitoring network. Methods Through the design concept of modularization, specialization and scalability, the project succeeded in completing the design goal by adopting a reliable quality management system and adopting mature accessories. Results The developed detector was measured with Na I (Tl) at a dose equivalence ratio of 10 nSv / h to 150 μSv / h and a nuclide identification was carried out. A GM was used between 10 μSv / h and 3 Sv / h The tube is measured and sent back to the data processing center for processing and display via a wireless transmission module with 3 G and RF redundancy design. Conclusion The completed detector can meet the needs of emergency monitoring after an accident.
