The RPC muon detector of the CMS experiment at the CERN Large Hadron Collider uses fluorine-based gases in volumes made by bakelite plates, in high-radiation environment. Studies of radiation damage on bakelite are presented. Bakelite samples were taken from gaps irradiated at the GIF. Preliminary results on an analysis campaign based on SEM-EDS, XRD and chemical analyses performed on a high-statistics sample will be discussed.
