Abstract The W-MON project aims to improve and automatize the control of the presence of radioactive material in conventional waste containers at CERN using a distributed network of interconnected low-power radiation sensors. The key development is the integration of a lightweight but sensitive radiation sensor in a powerful network that allows continuous data recording, transfer and storage in a database for alarm triggering and subsequent data analysis. The Chiyoda D-shuttle personal dosimeter was used as proof-of-concept. Extensive tests performed with the commercial version of the D-shuttle showed that its robustness, stability under variable thermal conditions, high sensitivity and hourly dose logging capabilities make it a strong candidate for the project. To comply with the requirements of remote operation and wireless data transmission to a central server, a customized version of the D-shuttle has been developed. Two additional radiation sensors are also currently being considered. The sensors have been coupled to a custom-made communication board allowing for long-range low-power LoRa wireless data transmission. A centralized IoT (Internet of Things) end-to-end data architecture has been developed for real-time monitoring and visualization of the radiation level in waste containers before the final integration into REMUS, the overall CERN Radiation and Environment Monitoring Unified Supervision service.

用于环境放射监测的分布式互连传感器网络

摘要 W-MON 项目旨在使用互连的低功率辐射传感器的分布式网络改进和自动化 CERN 常规废物容器中放射性物质存在的控制。关键的发展是将重量轻但灵敏的辐射传感器集成到一个强大的网络中，该网络允许连续数据记录、传输和存储在数据库中，以用于警报触发和后续数据分析。Chiyoda D-shuttle 个人剂量计被用作概念验证。对商业版 D-shuttle 进行的大量测试表明，其在可变热条件下的稳健性、稳定性、高灵敏度和每小时剂量记录能力使其成为该项目的有力候选者。为了满足远程操作和无线数据传输到中央服务器的要求，开发了定制版本的 D-shuttle。目前还在考虑另外两个辐射传感器。传感器已耦合到定制的通信板，允许远距离低功耗 LoRa 无线数据传输。在最终集成到 REMUS（整个 CERN 辐射和环境监测统一监管服务）之前，已经开发了集中式 IoT（物联网）端到端数据架构，用于实时监测和可视化废物容器中的辐射水平。传感器已耦合到定制的通信板，允许远距离低功耗 LoRa 无线数据传输。在最终集成到 REMUS（欧洲核子研究中心辐射和环境监测统一监管服务）之前，已经开发了集中式 IoT（物联网）端到端数据架构，用于实时监测和可视化废物容器中的辐射水平。传感器已耦合到定制的通信板，允许远距离低功耗 LoRa 无线数据传输。在最终集成到 REMUS（整个 CERN 辐射和环境监测统一监管服务）之前，已经开发了集中式 IoT（物联网）端到端数据架构，用于实时监测和可视化废物容器中的辐射水平。
