Abstract The radiation damage characteristics of three types of plastic scintillators, BC-408, EJ-200 and BC-404, are experimentally studied. The results show that after irradiation, the light yield and light transmission of these scintillators decrease and the shapes of the excitation and emission spectra remain unchanged. Recovery of light yield is not observed after weak irradiation.
