The scintillation light yield quenching of Ce-doped Gd2SiO5 (GSO) single crystals under proton and 241Am α-particle irradiation has been investigated. Pulse height spectra of protons with the deposited energies of 1.5–3.4 MeV were measured at The Wakasa Wan Energy Research Center. In addition, pulse height spectra of 241Am α-particles with the deposited energies of 1.62–5.41 MeV were measured. By comparing the experimental results of scintillation outputs with simulations, the Birks parameter of GSO was estimated to be 0.01 mm/keV.
