特种条件下应急辐射监测系统研制

目的 本文研制的应急监测系统，能够提供特种环境条件下事故现场环境辐射水平监测的能力，为应急决策提供技术支持。方法 用无人机携带探测器并将其抛投布置到事故现场，监测结果通过无线数据传输模块将设备获取的剂量率信息和地理坐标发送到数据管理服务器，通过结构、空气动力学设计等使探测器具有耐受高温、高湿、强震、强辐射等特种条件的能力。结果 探测器通过无人机载带至高度30 m~100 m的空中抛投降落无损坏，探测器防护等级达到IP68，不更换电池持续工作时间大于1个月，在-20℃~80℃的环境温度下正常运行。结论 探测器系统能够在发生重大核事故后，通过无人机快速投掷到现场，并在特种条件下持续工作提供现场的环境辐射水平数据，弥补了技术空白。

Development of emergency radiation monitoring system for special conditions

Objective An Emergency Radiation Monitoring System was developed for special environment conditions. It is helpful for emergency actions.Methods Using UVA carries and throws radiation detectors to the accident area, the detectors transmit radiation and position data to computer by wireless data transmission module. Based on the structure and aerodynamic design, the detector has the ability of resistance of high temperature, high humidity and strong impact.Results After thrown from 30~100 m height, the detector can continually work more than one month. The detector get the protection grade of IP68 and can work well at the temperature of -20℃~85℃.Conclusion It can fulfill the needs of emergency radiation monitoring after severe nuclear accident.
