The use of silicon photomultipliers for reading optical information from scintillators was investigated. Measurements were taken with scintillating fibers, tiles, and high-Z scintillators. In experiments with silicon photomultipliers, it was shown that relativistic particles were detected in scintillating fibers with an efficiency of 97-98% and that there were about nine photoelectrons. When information was read out of scintillator tiles via wavelength shifting fibers, the number of photoelectrons was ～15. The energy resolution of detectors based on LSO crystals was ～25% for y rays with energies of 500-600 keV.
