Screening systems. Technological development has two sides of the same coin: on the one hand the technologic progress is fraught with energy aimed at improving the quality of life of mankind, on the other the energy is used for destruction. Safety is the key state for the development and creation of the future life, especially when it comes to the safety of people. Screening systems installed in places of mass gathering: airports, stations, stadiums are based on the same principle of operation as medical scanners: emission source, receiver and data processing with displaying on the screen or as a signal. CsI(Tl) is the conventional material for screeners. It is relatively cheap material with a certain property set that currently satisfies scanner manufacturers. Fomos-Materials proposes to use GGAG:Ce as a scintillation radiation detector in the new generation devices.
