Abstract: Plastic scintillators are very often used as detecting media in sampling calorimeters of High Energy Physics (HEP). Many modern HEP experimental installations are already operating or proposed to work at high luminosity. Plastic scintillators are the most sensitive part of such setups in terms of their radiation hardness. Improving the light collection from the most irradiated scintillators will ensure their long-term use at high luminosity. The experimental results of the measurements for different assemblies (scintillator SCSN-81 and the WLS fiber Y-11 electron-irradiated (E~4MeV) were obtained. Calculations of the light yields for different samples based on our experimental results show the possibility of increasing the radiation hardness of plastic scintillators inside the sampling calorimeter up to 20Mrad.
