An IoT System for Detection and Identification of Radioactive Material in Scrap Metal Recycling

Abstract

In this paper, we propose and develop an Internet of Radiation Sensor System (IoRSS) to enhance the use of nuclear detection systems to detect nuclear and other radioactive materials out of regulatory control in scrap metal recycling and production facilities. This is a complete IoT system of stationary and portable radiation detection devices connected to a radiation detection network using LoRa communication. With a robust and flexible network architecture along with advanced data fusion algorithms that combine information from many detectors, the IoRSS provides an advanced search, detection, and identification in the presence of radioactive material across a large coverage area and in difficult operational environments. The IoRSS demonstration has facilitated improved situational awareness and better capabilities to detect, identify, locate, and respond to incidents by integrating data from multiple portable and stationary radiation detectors across distributed sensors.
