  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.
