The spectrometric characteristics of zinc-selenide-based scintillators under alpha, beta, andgamma excitations have been investigated. The optimal conditions of signal collection for energyresolution measurements have been determined. The resolution of ZnSe(O)-Si-PD (PD =photodiode) for alpha particles (239Pu, E = 5.15 MeV) is 3.1 %; for the beta particles (207Bi, E= 976 keV), it is 3.7 %; and for gamma quanta (137Cs, E = 662 keV), it is 6.3 %. High lightoutput, satisfactory energy resolution, and an /ratio which close to one allow for application ofZnSe-based scintillators for alpha particle, beta particle, and gamma quanta identification.
