This paper describes a prototype of a compact environmental radiation surveillance instrument designed for a Ranger unmanned aerial vehicle. The instrument, which can be used for tracking a radioactive plume, mapping fallout and searching for point sources, consists of three different detector types (GM, NaI(Tl) and CZT) and an air sampling unit. In addition to the standard electronics for data acquisition, the system contains an onboard computer, a GPS receiver and environmental sensors, all enclosed in a single housing manufactured of fiberglass-reinforced composite material. The data collected during the flight is transmitted in real-time to the ground station via a TETRA radio network. The radiation surveillance unit is an independent module and as such can be used in, for example, airplanes, helicopters and cars.
本文描述了一种为“游侠”无人机设计的紧凑型环境辐射监测仪器的原型。该仪器可用于追踪放射性烟羽、绘制沉降物分布图以及搜索点源，它由三种不同的探测器类型（盖革-弥勒计数管、碘化钠（铊）探测器和碲锌镉探测器）以及一个空气采样单元组成。除了用于数据采集的标准电子设备外，该系统还包含一台机载计算机、一个全球定位系统接收器和环境传感器，所有这些都封装在一个由玻璃纤维增强复合材料制成的单一外壳中。飞行过程中收集的数据通过TETRA无线网络实时传输到地面站。辐射监测单元是一个独立模块，因此可用于例如飞机、直升机和汽车等。
