Sumario:Among the CMS upgrades in preparation for LHC RUN-3 is the installation of 144 new muon detectors based on Gas Electron Multiplier (GEM) technology at Station1 in the endcap region. In each endcap, there are integrated RadMon (active radiation sensor) units that are installed on six GEM detectors to measure the total dose and particle flux. Every RadMon contains Radiation-sensitive Field Effect Transistors (RadFETs) and p-i-n diodes for estimation of the absorbed dose and 1MeV neutron equivalent (neq) fluence respectively. The radiation readout system structure and the analysis of the data collected before the start of LHC RUN-3 are described.
