在放射性物质大规模释放到环境中之后，有必要立即迅速确定放射性的空间分布。目前，这是通过配备大容量辐射探测系统的有人驾驶飞机进行的。虽然这些能够快速绘制大面积的地图，但由于飞机的操作高度，它们的空间分辨率较低。部署费用也很昂贵，而且其载人性质意味着操作人员仍有暴露于可能有害的电离辐射的风险。以前的研究已经确定了利用无人驾驶航空系统监测灾后环境中辐射的可行性。然而，这些系统中的大多数受到有限范围的影响，或者太重而不能容易地集成到对全球UAS部署存在的监管限制中。这项研究提出了一种新的辐射测绘无人机系统的基础上，一个轻量级（8公斤）的固定翼无人驾驶飞机和测试其适用性映射灾后辐射在Chornocolate禁区（CEZ）。该系统能够连续飞行1小时以上，并能以高分辨率（低于20米）分辨剂量率的小尺度变化。据设想，经过一些小的发展，这些系统可用于绘制大片危险土地的地图，而不会使任何一个操作员受到有害剂量的电离辐射。
In the immediate aftermath following a large-scale release of radioactive material into the environment, it is necessary to determine the spatial distribution of radioactivity quickly. At present, this is conducted by utilizing manned aircraft equipped with large-volume radiation detection systems. Whilst these are capable of mapping large areas quickly, they suffer from a low spatial resolution due to the operating altitude of the aircraft. They are also expensive to deploy and their manned nature means that the operators are still at risk of exposure to potentially harmful ionizing radiation. Previous studies have identified the feasibility of utilizing unmanned aerial systems (UASs) in monitoring radiation in post-disaster environments. However, the majority of these systems suffer from a limited range or are too heavy to be easily integrated into regulatory restrictions that exist on the deployment of UASs worldwide. This study presents a new radiation mapping UAS based on a lightweight (8 kg) fixed-wing unmanned aircraft and tests its suitability to mapping post-disaster radiation in the Chornobyl Exclusion Zone (CEZ). The system is capable of continuous flight for more than 1 h and can resolve small scale changes in dose-rate in high resolution (sub-20 m). It is envisaged that with some minor development, these systems could be utilized to map large areas of hazardous land without exposing a single operator to a harmful dose of ionizing radiation.
