There were studies the radiation resistance of organic plastic scintillators UPS-923A, SCSN-81, SC-301 and SC-307 based on polystyrene, and scintillators BC-408 and EJ-260 based on polyvinyl toluene. There were also studied properties of irradiated Tyvek and ESR reflectors; Paint + TiO2, PMS + TiO2 and Epoxy + TiO2 coatings. The results of this work are aimed at the creating of a radiation-resistant CMS Hadron Endcap Calorimeter at the Large Hadron Collider. The CMS detector is currently being upgraded to study the Higgs boson under the high luminosity conditions.
