英格兰康沃尔郡铀矿脉的历史开采导致大量的传统放射学污染物传播到许多长期废弃的采矿地点。包括这些站点的记录不佳和老化状况的因素以及放射性高度局部的性质限制了传统调查方法的成功。一个新开发的无人驾驶空中系统[UAS]携带集成的伽马辐射映射单元用于单个传统采矿地点的放射学表征。使用该仪器生成高空间分辨率图，可以确定放射学污染的土地区域，并迅速识别和量化污染程度及其同位素性质。该仪器被证明是在全球表征类似站点的可行工具。 （c）2015年作者。由Elsevier Ltd.出版。
Historical mining of uranium mineral veins within Cornwall, England, has resulted in a significant amount of legacy radiological contamination spread across numerous long disused mining sites. Factors including the poorly documented and aged condition of these sites as well as the highly localised nature of radioactivity limit the success of traditional survey methods. A newly developed terrain-independent unmanned aerial system [UAS] carrying an integrated gamma radiation mapping unit was used for the radiological characterisation of a single legacy mining site. Using this instrument to produce high-spatial-resolution maps, it was possible to determine the radiologically contaminated land areas and to rapidly identify and quantify the degree of contamination and its isotopic nature. The instrument was demonstrated to be a viable tool for the characterisation of similar sites worldwide. (C) 2015 The Authors. Published by Elsevier Ltd.
