The radioactive pollution of iron ore imported via Beilun Port was studied by measuring the imported iron ore deposited at Beilun Port. 通过对堆放在北仑港口的进口铁矿石进行放射性水平测量,研究了北仑港口进口铁矿石的放射性污染状况。
This paper has discussed the airborne monitoring of radioactive contamination formed during exploitation and utilization of iron ore and coal ore, analyzed the Gamma Radiant Eminence Map of China, and determined several relatively high radioactivity level regions, thus showing the effects of airborne radioactivity survey. 通过对铁、煤开发利用中形成的放射性热点的成功航空检测,以及对中国辐射照射量率图的分析,确定了几个放射性水平偏高区域,从而阐明了航空放射性测量在环境检测中的作用。
