Popis:	In this paper results of scintillation properties measurements of pure and Ce3+-doped strontium fluoride crystals are presented. We measure light output, scintillation decay time profile and temperature stability of light output. X-ray excited luminescence outputs corrected for spectral response of monochromator and photomultiplier for pure SrF2 and SrF2-0.3 mol.% Ce3+ are approximately 95% and 115% of NaI-Tl emission output, respectively. A photopeak with a 10% full width at half maximum is observed at approximately 84% the light output of a NaI-Tl crystal after correction for spectral response of photomultiplier, when sample 10x10 mm of pure SrF2 crystal is excited with 662 KeV photons. Corrected light output of SrF2-0.3 mol.% Ce3+ under 662 KeV photon excitation is found at approximately 64% the light output of the NaI-Tl crystal. Comment: 4 pages, 4 figures and 1 table
