摘　　要：提出了一种海上核应急三维辐射场快速反演方法。利用反距离权重方法,基于测量船上预安装的探测器定时回传的辐射监测值,不断迭代优化反演三维空间辐射场,实现真实场景情况下的光子剂量场与核素活度场耦合。结果表明,该方法能快速反演三维辐射场,满足核应急救援时间紧迫的需要,为核动力舰船等核设施应急提供有力的剂量评估与辐射场反演工具。This paper proposes a method for three-dimensional radiation field rapid inversion of nuclear emergency at sea.It uses inverse distance weight method to continuously invert and optimize the radiation field in three-dimensional space based on the radiation monitoring data of the detectors pre-installed on the ship.The results show that this method can quickly invert the three-dimensional radiation field,meet the urgent need of nuclear emergency rescue time,and provide powerful dose evaluation and radiation field inversion tools for nuclear emergency of nuclear vessels and other nuclear facilities.
