Abstract

A scalable private LoRaWAN-based monitoring system has been developed for indoor and outdoor radiation monitoring around nuclear facility. The system consists of open hardware-based radiation detection devices, indoor and outdoor LoRaWAN gateways, an open-source LoRaWAN network server and database server for storing measurement data. In addition, a commercial air quality monitoring device has been integrated to the proposed system to ensure its scalability. The aims of the system are to evaluate and validate the feasibility of low-cost open hardware based radiation measurement devices, development of private LoRaWAN based infrastructure for the monitoring data pipeline, and provide testbed of wireless-based security for radiation detection system. The system has been deployed and tested to measure the coverage of LoRaWAN network, and performance measurement of real-time radiation and environmental data collection for indoor and outdoor measurement. The result demonstrates that the maximum coverage distance between gateway and end-device is ~600 m depend on terrain, and the continuous transmission of real-time measurement data i.e. radiation dose rate, environmental and air quality data can be done within a few seconds interval. In the future, security assessment of the proposed system need to be performed to ensure the integrity and reliability of the system when deployed as a measurement system for protecting environment and people from the risk of radiation exposure.
