Gd₂SiO₅ (GSO) scintillator has very excellent radiation resistance with fast decay time and large amount of light yield. The radiation hardness of GSO was examined by using Carbon ion beams at Heavy Ion Medical Accelerator in Chiba (HIMAC). Through two nights of irradiation a GSO scintillator was received 7 × 10⁵ Gy of total dose and no decrease of light yield was observed. On the other hand an increase of light yield by 25% was observed. The increase is marginally proportional to the total dose at the rate of 0.025%/Gy and it is saturated at 1 kGy. Recovery to the initial light yield was also observed during the day between two nights. The time scale of recovery is about 15,000 seconds. In case of the LHCf experiment, very forward region (pseudo-rapidity > 8.4) experiment at the LHC, the irradiation rate is expected to about 100Gy for 10nb^-1 of data taking at vs = 14TeV proton-proton collisions. Expected increase of less than a few % will not be a big problem for the LHCf experiment.
