The absence of online radiation-monitoring systems (RMSs) has been observed in the case of the Fukushima nuclear accident. As the tsunami destroyed 23 of the 24 status-monitoring points, almost no relevant radiation dose measurement data were available. Rapid deployment of a mobile radiological unit that can quickly determine the activity and direction of the radioactive cloud spread on the ground or in the air can prevent unnecessary deaths and related financial losses. Although the design of the current generation of nuclear power plants (NPPs) incorporates features that minimize the risk of large radioactive releases outside the reactor, it is still important to focus on the development of systems that can mitigate the consequences of such events. In situations when the level of radiation does not permit the personnel to perform the required measurements, online unmanned RMSs may come into play. For such a purpose, the RMS-00x RMS could be used, which is a modular system covering the functionality of dose rate measurement, air sampling, and radiation map creation without requiring human personnel to be present at the measurement site. The main purpose of the RMS-00x RMS is the rapid deployment of unmanned monitoring devices to reduce the radiation burden on workers and on public. The system can be applied in the vicinity of an NPP or at any location, where the source of ionizing radiation could be present. Before this system is used in real conditions, its components must be thoroughly calibrated, based on certified measurement equipment and the state-of-art simulation tools. This article deals with the description of the RMS-00x sensor modules and demonstrates their functionality in combination with unmanned aerial vehicles (UAVs). In addition, the use of the developed technology was demonstrated as part of the regular emergency planning and preparedness exercise of Jaslovksé Bohunice NPP (EBO NPP) on October 26, 2017.

无人辐射监测系统

在福岛核事故的情况下，已经观察到没有在线辐射监测系统 (RMS)。由于海啸摧毁了 24 个状态监测点中的 23 个，几乎没有相关的辐射剂量测量数据可用。快速部署可以快速确定在地面或空中传播的放射性云的活动和方向的移动放射单元，可以防止不必要的死亡和相关的经济损失。尽管当前这一代核电厂 (NPP) 的设计结合了将反应堆外大量放射性释放风险降至最低的功能，但重点开发可以减轻此类事件后果的系统仍然很重要。在辐射水平不允许人员执行所需测量的情况下，在线无人 RMS 可能会发挥作用。为此，可以使用 RMS-00x RMS，这是一个模块化系统，涵盖了剂量率测量、空气采样和辐射图创建的功能，无需人员在测量现场。RMS-00x RMS 的主要目的是快速部署无人监控设备，以减少工作人员和公众的辐射负担。该系统可应用于核电厂附近或任何可能存在电离辐射源的位置。在实际条件下使用该系统之前，必须根据经过认证的测量设备和最先进的模拟工具对其组件进行彻底校准。本文介绍了 RMS-00x 传感器模块，并展示了它们与无人机 (UAV) 结合使用的功能。此外，在 2017 年 10 月 26 日，Jaslovksé Bohunice NPP (EBO NPP) 定期应急计划和准备演习的一部分展示了使用开发的技术。
