Abstract :
In order to estimate the number of scintillation photons emitted in NaI(Tl) and plastic scintillators by gamma-rays, the number of photoelectrons from the photomultiplier photocathode was absolutely measured with several combinations of photomultipliers and scintillators. The photomultipliers were used as a vacuum photodiode. The number of scintillation photons was estimated by using the effective quantum efficiency and the collection efficiency of photons by the photocathode
