In the article we consider questions related to the processing of data obtained as a result of the modeling of a portable device for locating point-like sources of radiation. The set of computer programs designed to simulate the passage of radiation through the detector block of the device and programs for data processing is presented. Programs Tank3 and Tank3Analysis are parts of the program complex. The Tank3 is a program for simulation of the passing of gamma rays through the detector block of the device. The Tank3Analysis program uses the results of simulation and is designed for data processing. The Tank3 program was developed in Linux using a C++ programming language and uses the Geant4 toolkit. The Tank3Analysis program is the program for data processing and uses the simulated response of the detectors of the experimental setup as an input data. Calculations were performed with the use of object-oriented programming. These results allow us to conclude the possibility of unambiguous determination of the direction to the point-like source of a radiation in space.
