The pulse height distributions from eleven kinds of scintillators coupled with a photomultiplier(PMT) and with a silicon photodiode were measured for gamma-ray energies between 14 keV and 1836 keV and compared. The numbers of photoelectrons from the PMT photocathode and those of electron-hole pairs in the photodiode were obtained. The intrinsic pulse height broadening was clearly demonstrated in NaI(Tl), CsI(Na), CsI(Tl) and CsI(pure) scintillators.
