he scintillation detector having crystal with 3.6cm dia2.0 cm thick was provided. The energy and timing characteristics were measured and compared with NaI(Tl) scintillation detectors, which widely used in unclear medicine. In order to measure the energy spectrum, the radioactive sources used were and the source to detector distance was 7cm. For the timing characteristic, NaI(Tl)(1" 1")- and NaI(Tl)(3" 3")- timing coincidence systems were prepared and the used source was emitting 511keV annihilation photons. For the 511keV gamma-ray emitted from , It was revealed that the timing response of the detector was faster than NaI(Tl)(1" 1") and NaI(Tl)(3" 3") detector used in this experimental investigation. The energy characteristics of the detector had a good values for about 500keV energy range.
