We show the possibility of the simultaneous registration of alpha-particles and gamma-quanta by means of separation of the decay kinetics of SCF and crystal parts of such CSs. Namely, the significant differences in the scintillation decay kinetics of LuAG:Pr SCF/LuAG:Ce SC and LuAG:Sc SCF/LuAG:Ce SC CSs under excitation by alpha-particles of Am-241 (5.5 MeV) source and gamma-quanta of Cs-137 (662 keV) source are observed. Thus, such types of CSs can be successfully applied for separation of the signals coming from their film and crystal parts at the registration of the mixed radiation fluxes of alpha-particles and gamma-quanta.
