Compact gamma detector module for radiation monitoring

Modern unmanned technologies make it possible to implement them in almost all industries, including radiation monitoring. Already in 2011, at the Fukushima nuclear power plant accident, the first drones were demonstrated to measure the radiation background of the territories. Improvement of such devices is one of the topical directions. Our research team has proposed the concept of a gamma radiation detector module for unmanned aerial vehicles. The concept is represented by a matrix of modernized silicon photomultipliers based on silicon structures. The new structures have a design of deep pixel photodiodes of the MLPD type. Today experimental samples have superiority in such parameters as high efficiency of registration of ionizing radiation. Also, such parameters as low sensitivity to vibrations and low power consumption of photodiodes make it possible to integrate them into unmanned and small-sized radiation monitoring systems.
