The ATLAS-GaAsPix system is a network of GaAs:Cr-based Timepix pixel detectors installed in various points of the ATLAS detector in the framework of the collaboration between JINR, IEAP CTU, CERN and Tomsk State University. The ATLAS-GaAsPix project provides installation of 10 Timepix detectors (5 singles, 5 twins) with GaAs:Cr sensors nearby Timepix detectors of the ATLAS-TPX system. First three detectors of the system were installed during YETS 2015-2016 and have successfully functioned during the LHC operation in 2016. In this work we present the first results obtained with ATLAS-GaAsPix detectors including the estimation of radiation fluxes in the ATLAS cavern for different particles. This is made possible by the use of developed procedure of the particle identification based on the shape of the particle track and deposited energy. Experimental results are consistent with numerical simulations.
