摘要: 提出了一种基于低空测量数据的地面放射性污染分布重建算法,该算法可以应用在“脏弹”爆炸后放射性污染分布重建计算中。该算法通过求解探测器响应系数方程组进而重建出地面污染分布,研究显示该算法在探测高度小于50 m时能比较好地重建地面放射性污染的分布。

Abstract: A reconstructing algorithm based upon the data taken by the low altitude measuring system is introduced in this paper. The algorithm reconstructs the radiological contamination distribution through solving the detection response factor equation set (DRFES). The study shows that the reconstructing algorithm performs well when the detection height is lower than 50 meters.

Key words: nuclear terrorisms, emergency monitoring, low altitude measurement, contamination distribution reconstructing
