An experimental study on GSO(Ce) scintillation crystals was made in terms of the light output response to proton in an energy range up to 161 MeV. The experiment was carried out for cubic crystals of 43 mm edge length by using a 392 MeV proton beam. A good linearity was observed between 30 and 161 MeV, and a slight non-linearity below 30 MeV. A relation of dL/dE versus E was determined with stopping protons. A calculation using the relation has agreed with measured pulse heights of protons penetrating the crystal, as well as those of stopping protons. Similar measurements were made for NaI(Tl) crystals of 2 in. cubic. Rather large non-linearity was observed in the proton energy range 0-122 MeV.
