摘要
经调研,XTG-3000A型无人机辐射测量系统首次采用CeBr_(3)闪烁体阵列探测器,以该系统为例,通过分析该系统组成并建立实验研究条件,对阵列探测器分辨率、能量线性、晶体间的相互屏蔽作用、核电子学温度适应性、系统长途运输稳定性及整机系统高原适航能力进行测试。全面考察了该无人机辐射测量系统的完善程度,认为该自主研发的无人机辐射测量系统可在复杂条件下稳定工作,系统可靠。其采用4条CeBr_(3)闪烁体以X型交叉顺序布局方式对放射源方向探知的优势,对快速识别、准确定位失控放射源,减少搜寻人员所受照剂量具有重要的应用意义。
After investigation,the radiation measurement system of XTG-3000A UAV adopts CeBr_(3)scintillator array detector for the first time.Taking the system as an example,by analyzing the composition of the system and establishing experimental research conditions,the resolution of the array detector,energy linearity,mutual shielding between crystals,nuclear electronics temperature adaptability,long-distance transportation stability of the system and the plateau Airworthiness of the whole system were tested.The perfection of the UAV radiation measurement system is comprehensively investigated.It is considered that the self-developed UAV radiation measurement system can work stably under complex conditions and the system is reliable.It adopts four CeBr_(3)crystals arranged in X-type cross sequence,which has the advantage of detecting the direction of radiation sources,and meets the design expectation.It has important application significance for rapid identification and accurate positioning of uncontrolled radioactive sources and reducing the radiation dose received by searchers.
