摘　　要：目的在核与辐射事故情况下快速获取现场辐射场信息并加强属地化应急响应支持。方法采用GM计数管和Na I(Tl)闪烁体相结合的方式,拓展探测单元的γ剂量率测量量程并实时获取现场核素信息,监测数据通过内置冗余的无线传输方式(3G和RF)传至数据处理系统,系统具备气象和地理信息接口,能够实现现场污染趋势的可视化,并可对核事故释放的烟羽源项进行"反演"计算。结果探测单元结构轻便、可靠,能灵活地"散布"在事故现场周围,及时地为应急指挥中心提供决策支持。结论测试表明,本系统能够在核与辐射事故情况下为应急决策提供"一站式"服务。Objective To improve the emergency response capability during a nuclear or radiation accident. Methods The detection units, which assembled the Geige -Muler tubes and NaI（T1） spectrometers, can increase the dose rate measurement range and identify the nuclides real -timely. The monitoring data could be transferred to the monitoring station wirelessly by WCDMA or Radio Frequency module. The meteorological and geographical information could be integrated into the system soft-ware, which can provide the real -time dose rate, the contaminated distribution, and even deducing the release activity. Results The detection unit is light - weight and robust, which can be easily distributed to the accident scene and provide real - time information. Conclusion The experiment results show that the Distributed Emergency Monitoring System （DEMS） is intended to be a one - stop service on nuclear and radiation emergency decision making.
