Abstract：
Using ⁶⁰Co radioactive source, the radiation damage properties of three kinds of plastic scintillators, BC-408, EJ-200 and BC-404 were studied. By the study of the variation of transmission spectra,emission spectra and light yield, it can be found that the scintillators have good irradiation hardness at low dose. When the dose is over 1.44×10 ⁴Gy, the transmission spectrum becomes worse and the light output decrease very much. However, the emission spectrum is unchanged.
