Development of a Wireless Safety System Based on Multiple Radiation Detector for Nuclear Facilities

In this paper, a system is proposed for a Nuclear facility which is comprised of multiple detectors, controlled from a single receiver end with DHCP Address Reservation Network protocol. The radiation sensor is based on Geiger Muller tube (GMT) which is a reliable detector for the radioactive particulates in the gaseous effluent vented from nuclear facilities. The detectors are interconnected and controlled from a server by a remote operator. A real-time log can be generated from respective data sent by these multiple detectors. The detectors are also implemented such a way that it is able to interact with the operator through a graphical user interface. The generated data have been further used to plot a real-time graph with MATLAB which is integrated into the system. The system is tested under several radioactive sources considering the background radiation. The graphical interpretation of the radiation pattern in terms of count per minutes versus time was obtained from the received data. This proposed system allows the remote operator to record and store the data of different radiation levels emitted from the radioactive in different time which may be used to create a radiation emission curve of a whole year. The system may be used to detect any abnormal radiation level which may be harmful to the environment and associated with the warning system for the early detection during those adverse situations.
