摘　　要：本文介绍了应用我国核应急航空检测系统 ,在北方某地进行天然辐射水平扫面兼顾寻找放射源时 ,成功地捕获了大苑南的152 Eu辐射热点 ,估算总活度约在 4 .2 5× 10 8～ 7.5 3× 10 8Bq(11.5～ 2 0 .4m Ci)之间 ,热点的纵向定位误差不大于 15 m。This paper presents an example of successfully capturing a hotspot of man made radioactive 152 Eu in Dayuan when we carried out airborne survey for radioactivity levels in north China. The hotspot was on the front of the gate of a concrate pipe factory in Dayuan. The activity of the source was estimated roughly 4.25×10 8～7.53×10 8 Bq. The longitudinal positioning error was less than 15 m. (
