DEVELOPMENT OF A MOBILE CYBER-PHYSICAL SYSTEM FOR RADIATION MONITORING AND ANALYTICS IN UKRAINE

The article presents the results of a study aimed at developing a mobile cyber-physical system for monitoring and analyzing radiation background, addressing current challenges in environmental safety. The relevance of the topic stems from the need for rapid response to radiation incidents, insufficient coverage of existing stationary monitoring systems, and the necessity to involve the public in environmental control processes. An intelligent system is proposed, built on the architecture model "Collector – Smartphone – Server," which ensures real-time data collection, transmission, processing, and visualization using modern wireless communication and computational analysis technologies. The main components of the system include a sensor device based on the ESP32 microcontroller with the GGreg20_V3 radiation sensor, an Android mobile application for device-server communication, and a server-side component for data processing and analytics using neural networks. To evaluate the effectiveness of the proposed mobile cyber-physical system, two separate simulation environments have been developed. Each environment allows the study of system behavior under conditions closely resembling real-world operation. The main idea behind modeling is to compare the performance of mobile sensor-based detection of radioactive contamination sources against traditional static solutions. The simulation results indicate that mobile sensors detect 7–45 times more instances of radioactive contamination compared to static solutions under identical conditions, highlighting the advantage of a mobile approach in detecting both localized sources and dynamic radioactive spread zones. These findings confirm the feasibility of implementing the developed system as an efficient solution for prompt radiation monitoring. The proposed system is scalable, accessible to a wide range of users, and can be integrated into national environmental monitoring infrastructure, with the potential for volunteer and citizen involvement in radiation safety processes.
